Key words and phrases of the Christian faith — with original Hebrew and Greek meanings, key verses, and scholarly sources.
Atonement
/uh-TONE-ment/SalvationThe act of making things right between God and humanity through sacrifice.
Atonement describes the restoration of relationship between God and humanity broken by sin. The Hebrew kaphar means "to cover" — seen in the Old Testament sacrificial system where animal blood covered sin. The Greek hilasmos means "propitiation" — satisfying the just requirements of God. The word "atonement" itself was coined by the English Bible translator William Tyndale (c. 1526) to express the idea of "at-one-ment" — being made one with God.
"He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world."
— 1 John 2:2
"For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar."
— Leviticus 17:11
Why it matters
Atonement explains why Jesus had to die. It was not arbitrary — it was the only way the debt of sin could be fully and finally paid.
Adoption
/uh-DOP-shun/SalvationBeing brought into God's family as a fully loved, fully entitled child — not a servant, not a guest, a son or daughter.
The Greek huiothesia (from huios — son, and thesis — placing) means the act of placing someone as a son. Paul uses this word five times in the New Testament and it is one of his most distinctive descriptions of what salvation achieves. In the Roman world, adoption was a serious legal act: an adopted child lost all legal ties to their old family and gained full rights in the new one — including the right to inherit. A natural-born child could be disinherited; an adopted child, under Roman law, could not. Paul deploys this legal reality deliberately. Believers are not merely forgiven criminals — they are adopted children, with the full rights and standing of natural-born heirs. The gift of adoption is inseparable from the Holy Spirit: it is the Spirit who brings about adoption and who testifies to its reality by causing believers to cry "Abba, Father" (Romans 8:15–16). John uses different language but the same reality: "to those who received him, to those who believed in his name, he gave the right to become children of God" (John 1:12). The distinction from justification is important: justification changes your legal status before God (from guilty to righteous); adoption changes your relational status (from stranger to child). Both are given simultaneously at conversion, but they are distinct gifts. J.I. Packer famously called adoption "the highest privilege that the gospel offers" — higher even than justification.
"The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, "Abba, Father.""
— Romans 8:15
"But when the set time had fully come, God sent his Son, born of a woman, born under the law, to redeem those under the law, that we might receive adoption to sonship."
— Galatians 4:4–5
"Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God."
— John 1:12
Why it matters
Adoption means God did not merely tolerate you into his presence — he brought you into his family. You are not on probation. You are not a servant earning your keep. You are an heir. The same inheritance that belongs to the Son belongs to you — because you are now, by grace, a child of the same Father.
Abba
/AB-uh/God's CharacterFather — an intimate, familial address for God that Jesus used and invites his followers to use.
Abba is an Aramaic word for father, carrying a tone of familiarity and intimacy. It appears only three times in the New Testament — once on the lips of Jesus in Gethsemane (Mark 14:36), and twice in Paul's letters describing the experience of adopted children of God crying out to God as Father (Romans 8:15; Galatians 4:6). For generations, popular teaching claimed that Abba was equivalent to the English "Daddy" — an informal, childlike term. While this overstates the case (abba was used by adult children of their fathers as well as young children), the core point stands: it is an intimate, relational, familial address — not a formal title. The significance of Jesus using this word in Gethsemane cannot be overstated. He was in agony, facing the cross, and he addressed the God of the universe with the same word a Jewish child used to call their father. This was unprecedented in Jewish prayer — approaching the holy, majestic Creator with familial directness. Paul frames it as a defining marker of adoption: when the Spirit of God indwells a believer, one of the first things that happens is that they cry "Abba, Father" — they discover they have become children of God, not slaves.
""Abba, Father," he said, "everything is possible for you. Take this cup from me. Yet not what I will, but what you will.""
— Mark 14:36
"The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, "Abba, Father.""
— Romans 8:15
"Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, "Abba, Father.""
— Galatians 4:6
Why it matters
Abba is one of the most revolutionary words in the New Testament. The God before whom the seraphim veil their faces and cry "holy, holy, holy" — this same God invites the believer to call him Father. Not from a distance, not through a priest, not with formal religious language. Simply: Father.
Apostle
/uh-POS-ul/ScriptureOne who is sent out — a commissioned representative of Jesus Christ.
The Greek apostolos means "one who is sent" (from apostellō — to send). In the first century, the word was used in ordinary Greek for an envoy or commissioned messenger. Jesus gave it a specific meaning: he chose twelve apostles who were to be his primary witnesses and the founding authorities of the church. The qualifications for the original Twelve were strict: they had to have been with Jesus throughout his ministry and witnessed the resurrection (Acts 1:21–22). Paul, though not one of the Twelve, vigorously defended his apostolic status on the grounds of his direct encounter with the risen Christ on the Damascus road (1 Corinthians 9:1; 15:8–9; Galatians 1:11–17). The apostles' unique authority is reflected in the foundational nature of their teaching — the New Testament itself is largely apostolic testimony, either written by apostles or by their close associates. The church is described as "built on the foundation of the apostles and prophets" (Ephesians 2:20). Christians disagree on whether the apostolic office continues today (cessationist vs. continuationist views) or whether it was unique to the first generation. What is not disputed is the authority of the apostolic writings: the New Testament is the lasting form of apostolic witness.
"These are the names of the twelve apostles: first, Simon (who is called Peter) and his brother Andrew; James son of Zebedee, and his brother John..."
— Matthew 10:2
"Built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone."
— Ephesians 2:20
"Am I not an apostle? Have I not seen Jesus our Lord? Are you not the result of my work in the Lord?"
— 1 Corinthians 9:1
Why it matters
The apostles are the reason we have the New Testament. Their unique eyewitness authority — grounded in resurrection appearances — is what gives the Gospels and letters their weight. When you read Paul or John, you are reading the testimony of someone who encountered the risen Christ and was commissioned to proclaim it.
Ark of the Covenant
/ark of the KUV-uh-nunt/ScriptureA gold-covered chest that housed God's presence among Israel — and pointed forward to Christ.
The Ark of the Covenant was a gold-covered acacia wood chest built according to precise instructions given to Moses on Mount Sinai (Exodus 25:10–22). It contained three objects: the stone tablets of the Ten Commandments (the Word of God), a jar of manna (the bread God provided in the wilderness), and Aaron's rod that had budded (the sign of the true High Priest). A golden lid called the "mercy seat" — flanked by two golden cherubim — covered the Ark. This was the specific location where God promised to meet with Israel and speak to Moses. The cloud of God's glory — the Shekinah — rested upon it. The Hebrew Aron HaBrit literally means "chest of the covenant." It was housed first in the Tabernacle and later in the Holy of Holies within Solomon's Temple — a chamber so sacred that only the High Priest could enter it, and only once a year on Yom Kippur (the Day of Atonement), carrying blood to sprinkle on the mercy seat. The Ark disappeared from history after the Babylonian destruction of Jerusalem in 586 BC and is not mentioned among the items returned after the exile. Its ultimate fate remains unknown. Theologically, the Ark is not merely a relic — it is a type, a shadow of a greater reality. The Greek word for the mercy seat (hilasterion) is used in Romans 3:25 to describe Christ himself as the "propitiation" for sin. The contents of the Ark find their fulfilment in Jesus: the Word made flesh (John 1:14), the true bread from heaven (John 6:35), and the eternal High Priest (Hebrews 4:14). The connection between Mary and the Ark — developed from Luke 1's deliberate parallel with 2 Samuel 6 — is one of the richest pieces of biblical typology in the New Testament.
"There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you and give you all my commands for the Israelites."
— Exodus 25:22
"This ark contained the gold jar of manna, Aaron's staff that had budded, and the stone tablets of the covenant."
— Hebrews 9:4
"God presented Christ as a sacrifice of atonement, through the shedding of his blood — to be received by faith."
— Romans 3:25
Why it matters
The Ark shows that God's presence is not abstract — he condescends to dwell among his people in a specific, tangible way. Every feature of the Ark points to Christ: the Word it contained became flesh in him, the manna prefigures the bread of life, and the mercy seat is a picture of the cross where justice and mercy met. Understanding the Ark unlocks the typological logic running through the whole Bible.
Baptism
/BAP-tih-zum/Christian PracticeAn outward sign of inward faith — immersion in water symbolising death to sin and new life in Christ.
The Greek baptisma comes from baptizo meaning "to immerse" or "to dip." Baptism in the New Testament is closely associated with repentance and faith (Acts 2:38), union with Christ (Romans 6:3–4), and entry into the church. Denominations differ on mode (immersion vs sprinkling) and subjects (believers only vs infants). The Didache (c. 50–120 AD) — one of the earliest Christian documents — gives detailed instructions on baptism practice.
"We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life."
— Romans 6:4
"Peter replied, "Repent and be baptised, every one of you, in the name of Jesus Christ for the forgiveness of your sins.""
— Acts 2:38
Why it matters
Baptism is the public declaration of a private transformation — it says to the world: "I have died with Christ and been raised to new life."
Covenant
/KUV-uh-nunt/TheologyA solemn, binding agreement between God and His people.
A covenant is a formal, binding relationship established between parties with defined commitments and consequences. The Bible is structured around major covenants: Noahic, Abrahamic, Mosaic, Davidic, and the New Covenant in Christ. The Hebrew berit appears over 280 times in the Old Testament. Covenant theology, systematised by theologians like Johannes Cocceius (1603–1669), sees all of Scripture as the unfolding of God's covenant relationship with humanity.
""I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.""
— Jeremiah 31:33
"This cup is the new covenant in my blood, which is poured out for you."
— Luke 22:20
Why it matters
Understanding covenant helps you read the whole Bible as one unified story — God faithfully keeping His promises across thousands of years.
Canon
/KAN-un/ScriptureThe authoritative collection of books recognised as Scripture — the rule by which Christian teaching is measured.
The Greek kanōn originally meant a straight rod or measuring stick — hence a rule or standard. Applied to Scripture, "the canon" refers to the list of books recognised as divinely inspired and authoritative for Christian faith and practice. The Protestant Old Testament canon (39 books) follows the Hebrew canon accepted by the Jewish community. The Catholic and Orthodox canons include additional books known as the Deuterocanonicals (or Apocrypha) — Tobit, Judith, 1–2 Maccabees, Wisdom, Sirach, Baruch, and additions to Daniel and Esther — which Protestants do not regard as Scripture though they may have devotional value. The New Testament canon of 27 books was not formally defined at a single council — it developed through a process of recognition across the early church. The criteria used by early church leaders included: apostolicity (written by an apostle or close associate), orthodoxy (consistent with the rule of faith), and catholicity (widespread acceptance across churches). Bishop Athanasius of Alexandria listed all 27 New Testament books in his Easter letter of 367 AD — the earliest complete list matching the modern canon. The Council of Carthage (397 AD) formally ratified this list. It is important to note that the church did not create the canon — it recognised what God had already inspired. The books carried their own authority; the councils acknowledged it.
"All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
— 2 Timothy 3:16
"For prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit."
— 2 Peter 1:21
"He said to them, "This is what I told you while I was still with you: everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms.""
— Luke 24:44
Why it matters
The canon is the question behind all Christian questions: which books do we listen to? The 66 books of the Protestant Bible (or 73 for Catholics) are not there because a council voted them in — they are there because the church, over centuries, recognised in them the voice of God. The canon defines the boundaries of Christian truth.
Conviction
/kun-VIK-shun/TheologyThe Holy Spirit's work of making a person deeply aware of their sin, their need for righteousness, and the reality of judgment.
Conviction, in Christian theology, refers to the inward work of the Holy Spirit that brings a person to a genuine awareness of sin — not merely intellectual knowledge that something is wrong, but a felt weight of guilt and moral accountability before God. Jesus promised this ministry of the Spirit explicitly in John 16:8: "When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment." The Greek word elenchō carries the sense of exposing, reproving, or bringing something into the light — the Spirit essentially holds up the mirror of God's holiness against the human conscience. Conviction is not the same as condemnation. Condemnation is the judicial verdict of guilt; conviction is the Spirit's gracious work that precedes repentance and faith. Romans 8:1 makes clear there is "no condemnation for those who are in Christ Jesus" — but conviction remains the ongoing work of the Spirit in the believer's life, producing repentance and growth. The Reformers distinguished between what they called a "legal" conviction — a fear of punishment — and a "evangelical" conviction — a genuine sorrow over sin because it is an offence against a holy and loving God. The latter, sometimes called godly sorrow, is described in 2 Corinthians 7:10: "Godly sorrow brings repentance that leads to salvation and leaves no regret, but worldly sorrow brings death." Conviction is therefore the beginning of the gospel's work in a person — the door through which repentance enters.
"When he comes, he will prove the world to be in the wrong about sin and righteousness and judgment."
— John 16:8
"Godly sorrow brings repentance that leads to salvation and leaves no regret, but worldly sorrow brings death."
— 2 Corinthians 7:10
"For I know my transgressions, and my sin is always before me."
— Psalm 51:3
Why it matters
Conviction is where the gospel begins its work. Without a genuine sense of sin, there is no real need for a Saviour — only a self-improvement programme. Understanding conviction helps Christians distinguish between the Spirit's gracious work (which leads to repentance and life) and crushing guilt or condemnation (which the gospel removes). It also explains why genuine preaching of the Word produces discomfort before it produces peace.
Divine
/dih-VINE/TheologyOf or belonging to God — possessing the nature, attributes, and perfections of God himself.
The English word "divine" derives from the Latin divinus, meaning "of a god." In the New Testament, the Greek theios describes qualities that belong essentially and exclusively to God — his immortality, power, and moral perfection. The Hebrew El (and its plural Elohim) denotes the supreme Being with absolute authority over creation. Theologians distinguish the "divine nature" (what God essentially is) from his "divine attributes" (the qualities flowing from that nature: omniscience, omnipotence, omnipresence, eternity, and perfect goodness). Herman Bavinck's Reformed Dogmatics (1895–1901) offers the most comprehensive Protestant treatment of the divine nature, arguing that all of God's attributes are expressions of a single, undivided divine essence rather than separate additions to a basic being.
"His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness. Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature."
— 2 Peter 1:3–4
"For since the creation of the world God's invisible qualities — his eternal power and divine nature — have been clearly seen, being understood from what has been made, so that people are without excuse."
— Romans 1:20
Why it matters
Understanding what "divine" means prevents us from reducing God to a super-human or an impersonal force. The divine nature is categorically different from all created things — and the gospel's miracle is that through Christ, finite human beings are invited to "participate in the divine nature" (2 Peter 1:4).
Disciple
/dih-SY-pul/ScriptureA learner and follower — someone committed not just to a teacher's ideas but to his whole way of life.
The Greek mathetes (disciple) comes from manthano — "to learn." But in the ancient world, discipleship was not merely academic. A disciple did not just study a rabbi's teachings; he followed the rabbi, imitated his life, and aimed to become like him. The Hebrew talmid (from the same root as Talmud — teaching) carries the same weight. In Jewish discipleship culture, a student would leave home to live with and serve a rabbi, learning not from lectures alone but from daily proximity. Jesus followed this pattern but with a striking difference: rabbis waited for disciples to come to them; Jesus went and called his disciples (Mark 1:17). "Follow me" was not an invitation to a classroom — it was a summons to a life. Jesus's expectation of his disciples was total: deny yourself, take up your cross, follow me (Matthew 16:24). In the New Testament, "disciple" is the most common term for a Christian — used over 260 times in the Gospels and Acts. The Great Commission (Matthew 28:18–20) commands not just evangelism but disciple-making — "teaching them to obey everything I have commanded." A convert who is not growing in obedience and Christlikeness has not yet become what the New Testament means by a disciple.
""Therefore go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit.""
— Matthew 28:19
"Then he said to them all: "Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me.""
— Luke 9:23
"To the Jews who had believed him, Jesus said, "If you hold to my teaching, you are really my disciples.""
— John 8:31
Why it matters
Discipleship is the shape of the Christian life. Conversion is the beginning, not the destination. The goal is not just to believe the right things about Jesus but to become the kind of person Jesus is — and that happens through the daily, costly, joyful work of following him.
Election
/ih-LEK-shun/SalvationGod's sovereign choice of people for salvation — not based on foreseen merit, but on his own free grace.
Election (from the Greek eklogē — "selection" or "choice") is the doctrine that God sovereignly chooses, before the foundation of the world, those who will be saved. The Hebrew bachar ("to choose" or "to select") is used of God's choice of Israel as his covenant people — a choice grounded not in Israel's size, strength, or righteousness but purely in God's love and faithfulness to his promise (Deuteronomy 7:6–8). The New Testament extends this to individuals within the new covenant: Paul teaches that God "chose us in him before the creation of the world" (Ephesians 1:4) and that election is "not by works but by him who calls" (Romans 9:11). Election is one of the most contested doctrines in Christianity. Calvinist (Reformed) theology holds that election is unconditional — God chooses based on his own sovereign will, not on foreseen faith. Arminian theology holds that election is conditional — God elects those he foreknows will freely choose him. Both traditions affirm the doctrine of election; they disagree on its basis. What is not contested: election is always described in Scripture as a cause for humility and worship, never for pride; it is corporate as well as individual; and it is always in Christ — there is no election apart from union with him.
"For he chose us in him before the creation of the world to be holy and blameless in his sight."
— Ephesians 1:4
"For you are a people holy to the Lord your God. The Lord your God has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession."
— Deuteronomy 7:6
"Yet, before the twins were born or had done anything good or bad — in order that God's purpose in election might stand: not by works but by him who calls."
— Romans 9:11
Why it matters
Election is not a cold decree — it is a love story. Before you existed, before you had done anything right or wrong, God set his love on you. Whatever your view of its mechanics, election means your salvation is not ultimately the result of your choice alone — it is grounded in the unshakeable purpose of God.
Elohim
/el-oh-HEEM/God's CharacterGod — the all-powerful Creator and supreme Being, used from the very first verse of Scripture.
Elohim is the most general Hebrew word for God and the first name for God that appears in Scripture: "In the beginning, God (Elohim) created the heavens and the earth" (Genesis 1:1). It appears over 2,500 times in the Hebrew Bible. Elohim is a plural form of El (the basic Semitic word for a divine being), yet it consistently takes singular verbs when referring to the God of Israel — a grammatical feature that has intrigued scholars for centuries. Some see in this "plural of majesty," emphasising God's greatness; others, including many Christian theologians, see an early hint of the Trinity — a divine fullness that the New Testament would later reveal as Father, Son, and Holy Spirit. The singular El appears in compound divine names: El Shaddai (God Almighty), El Elyon (God Most High), El Roi (the God who sees). Elohim is also used of foreign gods, angels, and even human judges in certain contexts — making clear that the word itself denotes a category of being, while the God of Israel is the one true Elohim who stands above all others. The name emphasises God's power and majesty as Creator and sovereign ruler over all things.
"In the beginning God created the heavens and the earth."
— Genesis 1:1
"Hear, O Israel: The Lord our God, the Lord is one."
— Deuteronomy 6:4
"For you are great and do marvellous deeds; you alone are God."
— Psalm 86:10
Why it matters
Elohim opens the Bible by establishing who is in charge. Before anything else exists — before light, land, life — there is God. He is not a god among gods; he is the uncreated Creator on whom all else depends. Every claim of the Christian faith rests on this foundation.
El Shaddai
/el sha-DY/God's CharacterGod Almighty — the all-sufficient, all-powerful God who sustains and provides beyond natural limits.
El Shaddai is one of the oldest divine names in Scripture, revealed specifically to the patriarchs — Abraham, Isaac, and Jacob — before the name Yahweh was fully disclosed to Moses (Exodus 6:3). God introduces himself to Abraham as El Shaddai at the moment he confirms the covenant and changes Abram's name to Abraham (Genesis 17:1). El means "God" or "mighty one." Shaddai is one of the most debated Hebrew words in biblical scholarship. Ancient translations rendered it "Almighty" (Greek pantokrator; Latin omnipotens), suggesting sovereign power over all things. Some scholars connect it to the Akkadian shadu — "mountain" — suggesting El of the Mountain, a title common in ancient Near Eastern divine names. Others connect it to the Hebrew shad ("breast"), suggesting a nurturing, sustaining God — which would complement the patriarchal context of provision and covenant. Whatever its precise etymology, the name consistently appears in contexts of covenant confirmation, miraculous provision, and divine sufficiency in the face of human impossibility. Job, who faces suffering of the highest order, uses El Shaddai more than any other biblical writer — 31 times — as if the name itself carries the weight of wrestling with a God whose power is not in question even when his purposes are mysterious.
"When Abram was ninety-nine years old, the Lord appeared to him and said, "I am God Almighty; walk before me faithfully and be blameless.""
— Genesis 17:1
""I appeared to Abraham, to Isaac and to Jacob as God Almighty, but by my name the Lord I did not make myself fully known to them.""
— Exodus 6:3
"Whoever dwells in the shelter of the Most High will rest in the shadow of the Almighty."
— Psalm 91:1
Why it matters
El Shaddai was the name God gave himself to people living with impossible promises — a hundred-year-old man, a barren woman, a man sitting on an ash heap. The name says: I am enough. Whatever is lacking in your circumstances, I am sufficient for it. That message does not age.
Emmanuel
/ih-MAN-yoo-el/God's CharacterGod with us — the name that captures the central miracle of the Christian faith.
Emmanuel (or Immanuel) is a Hebrew name composed of three parts: im ("with"), anu ("us"), and El ("God") — literally "God with us." It appears first in Isaiah 7:14, given as a sign to King Ahaz during a political crisis: "Therefore the Lord himself will give you a sign: the virgin will conceive and give birth to a son, and will call him Immanuel." The immediate context refers to events in Isaiah's own generation, but Matthew explicitly quotes this verse as finding its ultimate fulfilment in the birth of Jesus (Matthew 1:23). The name functions as both a title and a theological declaration. It is not primarily about the name Jesus would be called in daily life — it is about what his birth means: the eternal God has entered the created world in human form. God is not watching from a distance. He has come. The Gospel of Matthew opens with "God with us" (1:23) and closes with Jesus's promise "I am with you always, to the very end of the age" (28:20) — a deliberate literary frame. The entire Gospel is bracketed by the presence of God with his people. Emmanuel also connects to the Shekinah theme running through the Old Testament: God's presence in the Tabernacle, the Temple, and now — definitively, personally, permanently — in a person.
"Therefore the Lord himself will give you a sign: the virgin will conceive and give birth to a son, and will call him Immanuel."
— Isaiah 7:14
""The virgin will conceive and give birth to a son, and they will call him Immanuel" (which means "God with us")."
— Matthew 1:23
""And surely I am with you always, to the very end of the age.""
— Matthew 28:20
Why it matters
Emmanuel is the answer to the loneliest question human beings ask: is anyone there? Is God paying attention? The Incarnation answers it not with a philosophy or a feeling but with a fact — God came. He is with us. Not as a concept. In person.
Faith
/fayth/Christian PracticeTrust and reliance on God — not just belief but confident dependence.
Biblical faith is not blind belief or wishful thinking — it is confident trust based on reliable evidence. The Hebrew emunah carries the idea of firmness and faithfulness. The Greek pistis means trust, belief, and loyalty combined. Hebrews 11:1 gives the classic definition. The Westminster Confession of Faith (1647) defines saving faith as "accepting, receiving, and resting upon Christ alone for justification, sanctification, and eternal life."
"Now faith is confidence in what we hope for and assurance about what we do not see."
— Hebrews 11:1
"Faith by itself, if it is not accompanied by action, is dead."
— James 2:17
Why it matters
Faith is the hand that receives the gift of salvation — not the price you pay for it, but the means by which you receive it.
Grace
/grays/SalvationUndeserved favour and kindness from God toward people.
Grace is the free, unmerited favour of God toward humanity. In the New Testament, the Greek word charis appears over 150 times and describes God's disposition to bless people regardless of their merit. Unlike mercy (which withholds deserved punishment), grace gives undeserved blessing. The Protestant Reformation, led by Martin Luther, placed grace at the centre of Christian salvation — summarised in the phrase "sola gratia" (grace alone).
"For it is by grace you have been saved, through faith — and this is not from yourselves, it is the gift of God — not by works, so that no one can boast."
— Ephesians 2:8–9
"All are justified freely by his grace through the redemption that came by Christ Jesus."
— Romans 3:24
Why it matters
Grace is the foundation of Christian salvation. Without it, no one could be saved — it means our standing before God depends entirely on what He has done, not what we do.
Gospel
/GOS-pul/TheologyGood news — specifically the good news about Jesus Christ.
The word gospel comes from the Old English "godspel" meaning "good news" or "good story," translating the Greek euangelion. In the Greco-Roman world, euangelion announced a great victory or the birth of an emperor. The New Testament radically reappropriates this word: the truly good news is not Caesar's reign but Christ's death and resurrection. The gospel is summarised in 1 Corinthians 15:3–4.
"Christ died for our sins according to the Scriptures, he was buried, he was raised on the third day according to the Scriptures."
— 1 Corinthians 15:3–4
"For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes."
— Romans 1:16
Why it matters
The gospel is the central message of the entire Bible — everything in Scripture points to or flows from this good news.
Glorification
/glor-ih-fih-KAY-shun/SalvationThe final stage of salvation — the resurrection and transformation of the believer's body into imperishable glory.
Glorification is the third and final phase of the ordo salutis (order of salvation), following justification (declared righteous) and sanctification (being made holy). It refers to the resurrection and complete transformation of the believer at the return of Christ — when the body that is "sown in dishonour" is "raised in glory" (1 Corinthians 15:43), and the corruption introduced by sin is finally and entirely reversed. The Greek doxazō means "to glorify" or "to honour" — to bring something into a state that reflects its true worth and splendour. In Romans 8:30, Paul uses the past tense for glorification — "those he justified, he also glorified" — even though it is a future event. This is the "prophetic perfect" in Greek: an event so certain in God's purposes that it can be spoken of as already accomplished. Glorification is not the salvation of the soul from the body — a Greek philosophical idea foreign to Scripture. It is the salvation of the whole person: body and soul together transformed and made fit for the new creation. The glorified body of Jesus — which could be touched, could eat, yet could pass through locked doors and ascend into heaven — is described as the "firstfruits" of our own future glorification (1 Corinthians 15:20–23). What happened to him on Easter morning will happen to every believer.
"And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified."
— Romans 8:30
"It is sown in dishonour, it is raised in glory; it is sown in weakness, it is raised in power."
— 1 Corinthians 15:43
"Who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body."
— Philippians 3:21
Why it matters
Glorification means Christianity is not about escaping the physical world — it is about its redemption. Your body matters. The resurrection matters. The future God promises is not an eternal church service in the clouds; it is the renewal of all things, beginning with the resurrection of the dead.
Gentile
/JEN-tyle/ScriptureAnyone who is not Jewish — and the people the gospel was always intended to reach.
Gentile comes from the Latin gentilis (of a nation or clan), translating the Hebrew goy ("nation" or "people") and the Greek ethnos (from which we get "ethnic"). In the Old Testament, goy could refer neutrally to any nation including Israel itself, but came to be used specifically for non-Israelite peoples. The Hebrew Scriptures contain a complex picture: Israel was chosen as a distinct people, yet the prophets consistently envisioned the Gentile nations streaming to Jerusalem and worshipping Israel's God (Isaiah 2:2–3; 60:3; Psalm 86:9). The inclusion of Gentiles in God's covenant purposes was not an afterthought — Abraham was told that "all peoples on earth will be blessed through you" (Genesis 12:3), a verse Paul quotes directly in Galatians 3:8 as "the gospel announced in advance." In Jesus's day, Jewish attitudes toward Gentiles ranged widely, but social separation was common — Jews and Gentiles did not typically eat together. The Jerusalem Council (Acts 15) settled the watershed question of the early church: Gentiles do not need to become Jewish (through circumcision and Torah observance) to be fully included in the people of God. Faith in Christ is the entry point, not ethnicity. Paul's mission to the Gentiles — grounded in his calling on the Damascus road (Acts 9:15) — opened the faith to the majority of humanity and fulfilled the promise made to Abraham.
""All peoples on earth will be blessed through you.""
— Genesis 12:3
"There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus."
— Galatians 3:28
"For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility."
— Ephesians 2:14
Why it matters
The inclusion of the Gentiles is not a New Testament footnote — it is the fulfilment of a promise made to Abraham two thousand years before Christ. The gospel is not a Western religion or a Jewish sect; it is the blessing that was always meant for every nation.
Holy Spirit
/HOH-lee SPIR-it/TheologyThe third person of the Trinity — the presence and power of God living in believers.
The Holy Spirit is not a force or energy but a person — the third member of the Trinity. The Hebrew ruach means "breath" or "wind"; the Greek pneuma carries the same meaning. The Holy Spirit convicts of sin, regenerates (gives new birth), indwells believers, and produces fruit (Galatians 5:22–23). John Owen's Pneumatologia (1674) remains one of the most thorough treatments of the Holy Spirit's person and work.
""I will ask the Father, and he will give you another advocate to help you and be with you forever — the Spirit of truth.""
— John 14:16–17
"But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control."
— Galatians 5:22–23
Why it matters
The Holy Spirit is not a bonus feature of the Christian life — He is the very life of it. Without Him, transformation is impossible.
Holy
/HOH-lee/God's CharacterSet apart, morally perfect, and utterly distinct from everything sinful or created.
Holiness is the most fundamental attribute of God — the one attribute Scripture emphasises by repetition above all others. Isaiah 6:3 records the seraphim crying "Holy, holy, holy" — not "love, love, love" or "power, power, power." The Hebrew qadosh means "to cut" or "to separate": holiness is God's radical otherness, his complete separateness from everything sinful, finite, or created. The Greek hagios carries the same meaning — set apart, consecrated, sacred. Rudolf Otto's landmark study The Idea of the Holy (1917) described this quality as the mysterium tremendum et fascinans — the overwhelming mystery that simultaneously terrifies and attracts. John Webster's Holiness (2003) develops the theological framework: God's holiness is not merely moral purity but the self-giving perfection of his being, from which both his judgment of sin and his grace toward sinners flow. Applied to believers, holiness (sanctification) means being set apart for God — progressively conformed to the character of the One who called them.
"And they were calling to one another: "Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory.""
— Isaiah 6:3
""Be holy, because I am holy." For it is written: "Be holy, because I am holy.""
— 1 Peter 1:15–16
Why it matters
Holiness is the lens through which every other attribute of God must be read. His love is holy love — not indulgent sentiment. His justice is holy justice — not mere rule enforcement. And the call to holiness in 1 Peter 1:15–16 is not a burden but an invitation: to reflect the very character of God in whom believers now live and move.
Heresy
/HER-uh-see/TheologyA teaching that contradicts the essential doctrines of the Christian faith — not a minor disagreement, but a departure from the gospel itself.
The Greek hairesis originally meant simply a "choice" or "sect" — a group that had chosen to follow a particular set of teachings. It appears in Acts to describe the Pharisees (Acts 15:5) and early Christians (Acts 24:5) without negative connotation. But by the New Testament letters, the word had taken on a darker shade: Paul warns of "destructive heresies" (2 Peter 2:1) and commands Titus to reject a divisive person after a first and second warning (Titus 3:10). In the early church, heresy came to mean specifically a teaching that contradicts the essential content of the gospel and the apostolic faith — particularly regarding the nature of God and the person of Christ. The great heresies of the first five centuries include: Arianism (Jesus is a created being, not fully divine — condemned at Nicaea, 325 AD), Docetism (Jesus only appeared to have a physical body), Nestorianism (Jesus is two separate persons — condemned at Ephesus, 431 AD), Eutychianism (Jesus's two natures merged into one — condemned at Chalcedon, 451 AD), Pelagianism (humans can achieve salvation through their own will without grace — condemned at Carthage, 418 AD). An important distinction: heresy concerns the core doctrines on which salvation depends — the Trinity, the Incarnation, the Atonement, Justification by faith. Disagreements on secondary matters (mode of baptism, forms of church government, eschatological timelines) are not heresies; they are denominational differences. Not every theological error is heresy — but some errors are serious enough to place a person outside the bounds of the historic Christian faith.
"But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them."
— 2 Peter 2:1
"But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God's curse!"
— Galatians 1:8
"I felt compelled to write and urge you to contend for the faith that was once for all entrusted to God's holy people."
— Jude 3
Why it matters
Knowing what heresy is protects you from two errors: calling everything you disagree with heresy (making the word meaningless), and being so reluctant to use the word that genuine departures from the gospel go unchallenged. The early church paid a high price in councils, controversy, and exile to define what Christianity actually is. That clarity was worth the cost.
High Priest
/hy preest/ScriptureThe chief priest of Israel — the one mediator between God and the people, who entered the Holy of Holies once a year to make atonement.
The High Priest (Kohen Gadol — literally "great priest") occupied the highest religious office in ancient Israel. Established through the Aaronic line (Aaron, the brother of Moses, was the first), the office was hereditary and held for life. The High Priest's unique functions included presiding over the Temple worship, pronouncing the divine name (YHWH) on Yom Kippur, and most critically, entering the Holy of Holies — the innermost chamber of the Tabernacle and later the Temple — once a year on the Day of Atonement to sprinkle sacrificial blood on the mercy seat and make atonement for Israel's sins. No other person could enter the Holy of Holies at any time. The High Priest wore distinctive garments including the ephod (a jewelled apron), a breastplate with twelve stones representing the twelve tribes, and a turban bearing a gold plate inscribed "Holy to the Lord" (Exodus 28). By the time of Jesus, the office had become deeply political — Caiaphas, who presided over Jesus's trial, held the position through Roman appointment. It was Caiaphas who declared it "better that one man die for the people" (John 11:50) — a statement John presents as unwitting prophecy. The letter to the Hebrews develops the High Priest typology more fully than any other New Testament document: Jesus is "a high priest who has passed through the heavens" (Hebrews 4:14), who offered not the blood of animals but his own blood, entering the true Holy of Holies — heaven itself — once for all (Hebrews 9:11–12). Aaron's rod that budded — a sign of his priestly appointment — was kept in the Ark alongside the manna and the tablets of the law.
"Therefore, since we have a great high priest who has ascended into heaven, Jesus the Son of God, let us hold firmly to the faith we profess."
— Hebrews 4:14
"He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, thus obtaining eternal redemption."
— Hebrews 9:12
"This is to be a lasting ordinance for you: atonement is to be made once a year for all the sins of the Israelites."
— Leviticus 16:34
Why it matters
Every time a High Priest entered the Holy of Holies, it was a picture of what Jesus would one day do perfectly and permanently. The old covenant required an annual repeat — because animal blood could never finally deal with sin. Christ's once-for-all entry into the heavenly sanctuary ended the need for repetition.
Incarnation
/in-kar-NAY-shun/TheologyGod becoming human in the person of Jesus Christ.
The Cambridge Dictionary defines incarnation as "the act of God coming to earth in the form of a human being, Jesus Christ." Theologically, the Incarnation is the doctrine that the eternal Son of God took on human flesh and became fully human while remaining fully divine. The term comes from the Latin in carne meaning "in flesh." The Council of Chalcedon (451 AD) defined this as two natures — human and divine — united in one person without confusion or separation. Athanasius of Alexandria (296–373 AD) defended this doctrine against the Arian heresy in his landmark work On the Incarnation, arguing that only a fully divine Christ could rescue a fully human race.
"The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth."
— John 1:14
"Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant."
— Philippians 2:6–7
Why it matters
The Incarnation means God knows what it feels like to be human — to suffer, to grieve, to be tempted. Jesus is not a distant deity but Emmanuel, God with us.
Intercession
/in-ter-SESH-un/Christian PracticePraying on behalf of someone else — standing in the gap between them and God.
Intercession is the act of pleading or petitioning God on behalf of another person or group. The Hebrew paga carries the sense of "meeting," "falling upon," or "coming between" — picturing the intercessor placing themselves between God and the one in need. The Greek entynchanō means to "meet with" or "approach on behalf of" someone. Intercession is not merely prayer for others — it is a specific posture of advocacy before God, modelled first by Abraham (Genesis 18), Moses (Exodus 32:11–14), and ultimately by Jesus himself, who "always lives to intercede" for believers (Hebrews 7:25). The New Testament adds a remarkable dimension: the Holy Spirit also intercedes, praying for believers "through wordless groans" when they cannot find words (Romans 8:26–27). Intercessory prayer is one of the primary ministries of the church and a reflection of the love of neighbour commanded in Scripture.
"Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them."
— Hebrews 7:25
"The Spirit himself intercedes for us through wordless groans."
— Romans 8:26
"I urge, then, first of all, that petitions, prayers, intercession and thanksgiving be made for all people."
— 1 Timothy 2:1
Why it matters
Intercession means no one prays alone. Jesus intercedes at the right hand of the Father, the Spirit intercedes within every believer, and Christians are called to intercede for one another. Prayer for others is not a minor spiritual discipline — it is the work of the church.
Inerrancy
/in-ER-un-see/ScriptureThe teaching that the Bible, in its original manuscripts, is without error in all that it affirms.
Inerrancy is the doctrine that the Bible, as originally written (in its autographs), is without error in everything it teaches or affirms — whether in matters of theology, history, ethics, or any other subject it addresses. The term derives from the Latin inerrans — "not wandering" or "not erring." It is grounded in the doctrine of inspiration: if the Holy Spirit superintended the human authors to produce exactly what God intended, and if God cannot lie (Titus 1:2; Hebrews 6:18), then the product of that inspiration cannot contain falsehood. The classic text is 2 Timothy 3:16 — "all Scripture is God-breathed" (theopneustos — literally "breathed out by God"). It is important to distinguish inerrancy from several things it is not: it does not claim that every translation is inerrant, only the original manuscripts; it does not require wooden literalism — biblical authors used phenomenological language, approximation, hyperbole, poetry, and metaphor without error; it does not claim that all parts of Scripture are equally important. The Chicago Statement on Biblical Inerrancy (1978), signed by over 300 evangelical scholars, remains the most carefully articulated definition. Infallibility is a related but slightly softer term — meaning the Bible will not lead you astray in matters of faith and practice, without necessarily making claims about every historical or scientific statement. Many Christians hold infallibility without full inerrancy; classical evangelicals hold both.
"All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
— 2 Timothy 3:16
""Sanctify them by the truth; your word is truth.""
— John 17:17
"All your words are true; all your righteous laws are eternal."
— Psalm 119:160
Why it matters
Inerrancy is not about defending a book — it is about trusting a God who speaks. If Scripture contains errors, the question immediately becomes: which parts? And who decides? Inerrancy draws a clear line: the Bible is what it claims to be — the word of God, trustworthy in all it affirms. That does not make interpretation easy, but it makes the text reliable.
Inspiration
/in-spuh-RAY-shun/ScriptureThe Holy Spirit's work in and through human authors to produce Scripture that is genuinely God's word.
Biblical inspiration refers to the supernatural work of the Holy Spirit in guiding the human authors of Scripture so that what they wrote was exactly what God intended — making the resulting text the very word of God. The foundational text is 2 Timothy 3:16: "all Scripture is theopneustos" — literally "God-breathed." The metaphor is not of God breathing into the text (as if the words were lifeless and required animation) but of God breathing out the text — Scripture is the product of divine exhalation, the word that proceeds from God. Peter adds the complementary image: "men spoke from God as they were carried along by the Holy Spirit" (2 Peter 1:21) — the Greek pheromenoi ("carried along") is used of a sailing ship driven by the wind. The human authors were not passive stenographers; their personalities, vocabularies, styles, and circumstances are all visible in the text. But neither were they merely expressing their own religious insights. The Holy Spirit worked through their humanity to produce a text that is simultaneously fully human and fully divine. This is known as the "organic" view of inspiration. Theories of inspiration vary: verbal plenary inspiration holds that the Spirit superintended the very words chosen; dynamic inspiration focuses on the ideas and thoughts rather than the precise words; neo-orthodox views regard Scripture as becoming the word of God when it encounters the reader. Classical Christianity has consistently held to verbal plenary inspiration — the entire text, down to the words, is inspired.
"All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
— 2 Timothy 3:16
"For prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit."
— 2 Peter 1:21
""For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.""
— Matthew 5:18
Why it matters
Inspiration is the reason the Bible is not merely an ancient library of religious reflection — it is the reason it speaks with authority. If the Holy Spirit truly produced these texts through human authors, then reading Scripture is not just historical research; it is hearing from God. That changes everything about how you approach the text.
Imputation
/im-pyoo-TAY-shun/SalvationThe crediting of righteousness to a person's account — God reckoning Christ's perfect record as yours.
Imputation is the theological term for the act of crediting something to someone's account — as in a financial ledger. The Greek logizomai means "to reckon," "to count," or "to credit." It appears 41 times in the New Testament and is central to Paul's argument in Romans. The doctrine of imputation has two dimensions: first, the imputation of Adam's sin to all humanity (Romans 5:12–19) — all bear the guilt and consequence of the first sin; second, and more gloriously, the double imputation of the gospel: our sin is imputed to Christ (he bore what we deserved — Isaiah 53:6; 2 Corinthians 5:21), and Christ's righteousness is imputed to us (we receive what he earned — Romans 4:22–24; Philippians 3:9). This is what Luther called the "great exchange" — the most unequal trade in history. Martin Luther's rediscovery of imputed righteousness was the theological engine of the Reformation. He found it in Romans 4:3 — "Abraham believed God, and it was credited (logizomai) to him as righteousness" — and understood that righteousness before God is not achieved by moral effort but received by faith. The alternative to imputed righteousness is infused righteousness — the Catholic view that righteousness is gradually worked into the believer through the sacraments. The difference is profound: imputed righteousness is complete and instantaneous at justification; infused righteousness is progressive and may remain incomplete at death.
"However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness."
— Romans 4:5
"God made him who had no sin to be sin for us, so that in him we might become the righteousness of God."
— 2 Corinthians 5:21
"For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous."
— Romans 5:19
Why it matters
Imputation means your standing before God does not depend on the quality of your obedience — it depends on the quality of Christ's. On your worst day, if you are in Christ, you stand before God clothed in a righteousness that is perfect, permanent, and not your own. That is the gospel.
I AM
/eye am/God's CharacterThe self-existent name of God — and Jesus's most direct claim to divinity.
When Moses asked God his name at the burning bush, God replied: "I AM WHO I AM" — in Hebrew, Ehyeh Asher Ehyeh (Exodus 3:14). This is the self-definition of a being who derives existence from nothing outside himself. He does not say "I was" or "I will be" but "I AM" — absolute, eternal, unconditioned presence. This name is the basis of the Tetragrammaton (YHWH), connecting God's personal name directly to the claim of pure, self-existent being. In the Gospel of John, Jesus makes seven famous "I am" statements with a predicate: "I am the bread of life," "the light of the world," "the good shepherd," "the resurrection and the life," "the way, the truth, and the life," "the true vine." But the most explosive use comes in John 8:58, when Jesus says without any predicate: "Before Abraham was, I am" (ego eimi). The crowd immediately attempted to stone him — because they understood exactly what he was claiming. He was not saying "I existed before Abraham." He was applying the divine name — the I AM of Exodus 3 — to himself. This is either the most audacious blasphemy in history, or the most important statement ever made. The Septuagint (Greek Old Testament) translates Ehyeh as ego eimi — the exact phrase John places on Jesus's lips. John's Gospel is structured to make this connection unmissable.
"God said to Moses, "I AM WHO I AM. This is what you are to say to the Israelites: 'I AM has sent me to you.'""
— Exodus 3:14
""Very truly I tell you," Jesus answered, "before Abraham was born, I am!""
— John 8:58
"Then Jesus declared, "I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.""
— John 6:35
Why it matters
The I AM statements are not poetic metaphors — they are claims. When Jesus says "I am the resurrection and the life," he is not offering an analogy. He is identifying himself with the God of the burning bush. Every time John records ego eimi on Jesus's lips, he is asking the reader: do you see who this is?
Justification
/jus-tih-fih-KAY-shun/SalvationBeing declared "not guilty" and righteous before God.
Justification is a legal term describing God's act of declaring a sinner righteous on the basis of faith in Christ. The Greek root dikaios means "righteous" or "just." Martin Luther's rediscovery of this doctrine — that justification is by faith alone (sola fide), not by works — sparked the Protestant Reformation in 1517. Luther described it as "the article by which the church stands or falls."
"Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ."
— Romans 5:1
"For we maintain that a person is justified by faith apart from the works of the law."
— Romans 3:28
Why it matters
Justification means your standing before God is secure — not based on your performance but on Christ's perfect record credited to you.
Kingdom of God
/KIN-dum of God/TheologyThe reign and rule of God — both a present reality and a future promise.
The Kingdom of God was the central theme of Jesus' teaching. The Greek basileia means "reign" or "rule" — not primarily a place but a dynamic reality of God's sovereign authority. Scholars debate whether it is "already" (present in Jesus' ministry) or "not yet" (fully arriving at His return). George Eldon Ladd's The Gospel of the Kingdom (1959) popularised the "already/not yet" framework that most evangelical scholars now accept.
""The time has come," Jesus said. "The kingdom of God has come near. Repent and believe the good news!""
— Mark 1:15
"Nor will people say, "Here it is," or "There it is," because the kingdom of God is in your midst."
— Luke 17:21
Why it matters
Understanding the Kingdom reframes the Christian life — you are not just waiting to escape to heaven but participating in God's renewal of all things right now.
Messiah
/meh-SY-uh/God's CharacterThe Anointed One — the promised deliverer sent by God.
Messiah comes from the Hebrew mashiach meaning "anointed one." In ancient Israel, kings, priests, and prophets were anointed with oil as a sign of divine appointment. The Jewish people expected a future Messiah who would restore Israel and establish God's kingdom. Jesus of Nazareth claimed to be this Messiah — a claim confirmed, Christians believe, by His resurrection. The Greek translation Christos gives us the title "Christ."
""I know that Messiah is coming," the woman said. Jesus declared, "I, the one speaking to you — I am he.""
— John 4:25–26
"The Spirit of the Sovereign LORD is on me, because the LORD has anointed me to proclaim good news to the poor."
— Isaiah 61:1
Why it matters
Understanding Messiah connects the entire Old Testament to Jesus — He is not a new idea but the fulfilment of centuries of promise.
Mercy
/MUR-see/God's CharacterNot giving people the punishment they deserve.
Mercy is the withholding of deserved judgment. The Hebrew hesed is one of the richest words in the Old Testament — often translated "steadfast love," "lovingkindness," or "mercy" — describing God's loyal, covenant love. The Greek eleos carries a similar meaning. Mercy differs from grace: mercy does not give what is deserved (punishment); grace gives what is not deserved (blessing). Katharine Doob Sakenfeld's The Meaning of Hesed (1978) is the definitive study of this word.
"Because of the LORD's great love we are not consumed, for his compassions never fail. They are new every morning; great is your faithfulness."
— Lamentations 3:22–23
"Blessed are the merciful, for they will be shown mercy."
— Matthew 5:7
Why it matters
Mercy is the reason any of us can stand before God. The cross is the ultimate act of mercy — justice was satisfied so that judgment could be withheld.
Manna
/MAN-uh/ScriptureThe miraculous bread God provided daily for Israel in the wilderness — and a type of Christ.
Manna was the supernatural food God provided to the Israelites during their forty years in the wilderness after the Exodus from Egypt (Exodus 16). Each morning, a fine flake-like substance appeared on the ground that could be ground, baked, or boiled. It tasted like wafers made with honey (Exodus 16:31). The Hebrew man is likely derived from the question the Israelites asked when they first saw it: "What is it?" (man hu). God gave strict instructions: gather only what you need for the day — no hoarding, no leftovers, except on the day before the Sabbath when a double portion was given. The purpose was explicit: "to humble and test you in order to know what was in your heart, whether or not you would keep his commands" (Deuteronomy 8:2–3). Manna ceased the moment Israel entered Canaan and could eat from the land (Joshua 5:12). A jar of manna was placed inside the Ark of the Covenant as a permanent memorial (Exodus 16:33–34; Hebrews 9:4). Jesus drew a direct line from the manna to himself in John 6 — declaring himself "the true bread from heaven" that gives eternal life, not merely sustained physical life. Where the manna kept Israel alive but could not prevent death, the bread of life overcomes it.
"Then the Lord said to Moses, "I will rain down bread from heaven for you.""
— Exodus 16:4
"Then Jesus declared, "I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.""
— John 6:35
"He humbled you, causing you to hunger and then feeding you with manna... to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord."
— Deuteronomy 8:3
Why it matters
Manna is one of the clearest Old Testament types of Christ. It came from heaven, not from earth. It was given freely, not earned. It sustained life daily. And it pointed to the one who would come down from heaven to give life that never ends.
Mercy Seat
/MUR-see seat/ScriptureThe golden lid of the Ark of the Covenant — the place where God met Israel and where atonement was made.
The mercy seat (kapporeth, from kaphar — "to cover" or "to atone") was the pure gold lid that covered the Ark of the Covenant, flanked by two golden cherubim with wings outstretched toward each other (Exodus 25:17–22). It was here that God promised to meet with Moses and speak to Israel: "There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you" (Exodus 25:22). Once a year, on Yom Kippur (the Day of Atonement), the High Priest entered the Holy of Holies and sprinkled the blood of a sacrificial animal on the mercy seat — making atonement for the sins of Israel for the year. The Greek Septuagint translates kapporeth as hilasterion — the same word Paul uses in Romans 3:25 to describe Christ: "God presented Christ as a hilasterion through the shedding of his blood." The mercy seat was not merely a lid. It was the place where the justice of God (the broken law contained within the Ark) and the mercy of God (the atoning blood applied above it) met. Paul is saying that what the mercy seat was in type, Christ is in reality — the place where divine wrath and divine love converge, where justice is satisfied and mercy is poured out.
"There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you."
— Exodus 25:22
"God presented Christ as a sacrifice of atonement, through the shedding of his blood — to be received by faith."
— Romans 3:25
"He shall then slaughter the goat for the sin offering for the people and take its blood behind the curtain and do with it as he did with the bull's blood: he shall sprinkle it on the atonement cover."
— Leviticus 16:15
Why it matters
The mercy seat is where justice and mercy met in the old covenant — and the cross is where they meet in the new. Paul's use of hilasterion in Romans 3:25 is not incidental. He is saying: what you looked at in the Holy of Holies, terrified and in awe, you now see in the person of Jesus Christ.
Original Sin
/uh-RIJ-uh-nul sin/TheologyThe inherited corruption and guilt that entered humanity through Adam's fall — the condition of sinfulness every person is born into.
Original sin refers to two related realities: the original guilt shared by all humanity as a result of Adam's sin (original guilt), and the inherited corruption of human nature that produces ongoing sinful desires and acts (original corruption). The term was coined and developed by Augustine of Hippo (354–430 AD), particularly in his controversies with Pelagius, who taught that humans are born morally neutral and sin only by imitation. Augustine argued from Romans 5:12–19 that Adam's sin was not merely an example to be avoided but an event that fundamentally altered human nature — introducing spiritual death, disordered desires, and moral inability that is passed down to every subsequent human being. The doctrine does not teach that sex or birth is sinful — it teaches that human nature itself is fallen and that no person arrives in the world in a morally neutral state. The Reformers sharpened this further with the doctrine of "total depravity" — not that humans are as bad as they could be, but that sin has corrupted every aspect of human nature: intellect, will, emotions, and desires. All major Christian traditions affirm some form of original sin, though they differ on its precise transmission, extent, and the status of unbaptised infants. The doctrine is not pessimistic — it is realistic. It explains why every society in history has produced injustice, cruelty, and self-destruction, and why the solution had to come from outside human nature altogether.
"Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned."
— Romans 5:12
"Surely I was sinful at birth, sinful from the time my mother conceived me."
— Psalm 51:5
"For all have sinned and fall short of the glory of God."
— Romans 3:23
Why it matters
Original sin is the honest diagnosis without which the gospel makes no sense. If humans are basically good and just need education or better environments, Christ's death is unnecessary. The doctrine insists the problem runs deeper — and therefore the solution must too. The cross is God's answer to a problem we could not solve ourselves.
Propitiation
/pruh-pish-ee-AY-shun/SalvationThe satisfying of God's righteous wrath through sacrifice.
Propitiation refers specifically to the appeasement of divine wrath. It is distinct from expiation (which removes guilt) — propitiation turns away God's righteous anger against sin. The Greek hilasterion is used in Romans 3:25 and also refers to the "mercy seat" on the Ark of the Covenant in the Septuagint (the Greek Old Testament). Leon Morris and John Stott defended this translation against those who preferred the softer "expiation."
"God presented Christ as a sacrifice of atonement, through the shedding of his blood — to be received by faith."
— Romans 3:25
"This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins."
— 1 John 4:10
Why it matters
Propitiation shows that the cross was not just about our forgiveness — it was about satisfying the justice of a holy God who cannot simply overlook sin.
Predestination
/pree-des-tih-NAY-shun/SalvationGod's eternal decision to appoint certain people to salvation in Christ before the foundation of the world.
Predestination (from the Greek proorizō — "to mark out beforehand" or "to decide in advance") is the doctrine that God, in eternity past, determined the destiny of his people. Paul uses the word in Romans 8:29–30 and Ephesians 1:5, 11. The word does not mean God foreordains everything that happens (that is the broader doctrine of providence); it refers specifically to God's advance appointment of people to be conformed to Christ and to receive salvation. Predestination has been one of the most debated doctrines in Christian history — sharply dividing Calvinists and Arminians since the Reformation. Calvinist (Reformed) theology teaches "double predestination": God elects some to salvation and passes over others (reprobation). Arminian theology teaches that predestination is based on God's foreknowledge of who will freely choose him — sometimes called "conditional election." The Lutheran tradition affirms predestination to salvation but rejects the Calvinist doctrine of reprobation. What all agree on is this: the word is used in Scripture as a comfort to believers, not a threat. Paul introduces predestination in Romans 8 in the context of assurance — "those he predestined, he also called; those he called, he also justified; those he justified, he also glorified" (8:30). The chain is unbroken. If you are in Christ, your future is settled.
"For those God foreknew he also predestined to be conformed to the image of his Son... And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified."
— Romans 8:29–30
"He predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will."
— Ephesians 1:5
"When the Gentiles heard this, they were glad and honoured the word of the Lord; and all who were appointed for eternal life believed."
— Acts 13:48
Why it matters
Predestination is not primarily a philosophical puzzle — it is a pastoral anchor. It means your salvation does not ultimately rest on the fragility of your own will or the consistency of your own faith. It rests on the eternal, unchanging purpose of God. Whatever you believe about its mechanics, that is a foundation worth standing on.
Prophet
/PROF-it/ScriptureSomeone called by God to speak his word — not primarily a predictor of the future, but a spokesperson for God.
The Hebrew navi likely derives from a root meaning "to call" or "to announce" — a prophet is one called by God to announce his word. The Greek prophetes similarly means "one who speaks forth" (pro = forth, phemi = to speak) rather than primarily "one who foretells." The popular image of a prophet as a future-predictor is correct but secondary — Old Testament prophets primarily confronted the present with the word of God, calling Israel to repentance, justice, and faithfulness to the covenant. Prediction of the future was often part of this — but as confirmation of divine authority, not as the core function. The prophetic office in Israel sat alongside the priestly and kingly offices. The great writing prophets — Isaiah, Jeremiah, Ezekiel, Daniel, and the twelve Minor Prophets — produced the bulk of the Old Testament. Moses is called the greatest prophet of the old covenant (Deuteronomy 34:10), and Deuteronomy 18:15 contains his promise that God would raise up a prophet like him — understood by the New Testament as fulfilled in Jesus (Acts 3:22). Jesus himself was recognised as a prophet (Matthew 21:11) and explicitly claimed more than prophetic status. In the New Testament, the gift of prophecy continues in the church (1 Corinthians 12:10; 14:1–5), though its nature and continuance is debated between cessationists and continuationists.
""I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth.""
— Deuteronomy 18:18
"In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son."
— Hebrews 1:1–2
"Surely the Sovereign Lord does nothing without revealing his plan to his servants the prophets."
— Amos 3:7
Why it matters
Understanding what a prophet actually was — a spokesperson, not just a predictor — transforms how you read the Old Testament. The prophets were not writing cryptic codes about future events; they were confronting their generation with the word of God. And the greatest of all prophets is the Word himself.
Pharisee
/FAIR-ih-see/ScriptureA Jewish religious sect in Jesus's time known for strict observance of the Law — and for whom outward religion had eclipsed the heart.
The Pharisees (from the Hebrew Perushim — "separated ones") were a major Jewish religious and political movement that emerged in the second century BC during the Maccabean period. They were deeply committed to the Torah — the written Law of Moses — and to the "oral Torah," an elaborate body of interpretation and tradition designed to build a fence around the Law and prevent accidental violations. Unlike the Sadducees (who controlled the Temple and denied the resurrection), the Pharisees believed in angels, the resurrection of the dead, and divine providence — putting them theologically closer to Jesus on several points. They were also the movement that survived the destruction of Jerusalem in AD 70 and gave rise to Rabbinic Judaism. In the Gospels, Jesus's harshest criticism is directed at the Pharisees — not because law-keeping is wrong, but because they had allowed meticulous external observance to mask internal corruption: "You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead" (Matthew 23:27). However, it would be historically simplistic to caricature all Pharisees as hypocrites — Nicodemus (John 3) came to Jesus sincerely, Joseph of Arimathea may have been sympathetic, and Paul was a Pharisee who became the greatest apostle (Philippians 3:5). The danger the Pharisees represent is not unique to them — it is the universal human tendency to substitute religious performance for genuine relationship with God.
""Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead.""
— Matthew 23:27
"Circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee... as for righteousness based on the law, faultless."
— Philippians 3:5–6
"Now there was a Pharisee, a man named Nicodemus who was a member of the Jewish ruling council."
— John 3:1
Why it matters
The Pharisees are not merely historical villains — they are a mirror. Anyone who has used religious discipline to build a sense of superiority, or kept the rules while hardening their heart, is in Pharisee territory. Jesus's confrontation with them is not a Jewish problem — it is a human problem.
Redemption
/rih-DEMP-shun/SalvationBeing bought back or set free from bondage to sin.
Redemption is the act of paying a price to liberate someone from slavery or bondage. In the Old Testament, the kinsman-redeemer (go'el) would buy back a family member sold into slavery. This imagery is fulfilled in Christ, who paid the ultimate price — His life — to free humanity from sin and death. The Greek apolytrosis literally means "release by payment of a ransom."
"In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace."
— Ephesians 1:7
"The women said to Naomi: "Praise be to the LORD, who this day has not left you without a kinsman-redeemer.""
— Ruth 4:14
Why it matters
Redemption means you are not just forgiven — you have been bought out of slavery to sin and brought into God's family.
Repentance
/rih-PEN-tuns/Christian PracticeA genuine turning away from sin and toward God.
Repentance is more than feeling sorry — it is a change of mind (Greek metanoia: meta = change, noia = mind) that leads to a change of direction. The Hebrew teshuvah means "to return" — to turn back to God. Martin Luther's very first of his 95 Theses (1517) states: "When our Lord and Master Jesus Christ said 'Repent' (Matthew 4:17), he willed the entire life of believers to be one of repentance."
"Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord."
— Acts 3:19
"Godly sorrow brings repentance that leads to salvation and leaves no regret, but worldly sorrow brings death."
— 2 Corinthians 7:10
Why it matters
Repentance is not a one-time event — it is the ongoing posture of a Christian life, continually turning from sin toward God.
Resurrection
/rez-uh-REK-shun/TheologyRising from the dead to a new, glorified bodily life.
Resurrection is not resuscitation (returning to the same mortal body) but transformation into a new, glorified, imperishable body. The Greek anastasis means "a standing up again." Jesus' resurrection is the cornerstone of Christian faith — Paul writes that without it, faith is futile (1 Corinthians 15:17). The historian N.T. Wright's The Resurrection of the Son of God (2003) is considered the most comprehensive scholarly defence of the historical resurrection.
"But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep."
— 1 Corinthians 15:20
"Jesus said to her, "I am the resurrection and the life. The one who believes in me will live, even though they die.""
— John 11:25
Why it matters
The resurrection is not just a miracle — it is the proof that Jesus' death actually accomplished something, and the guarantee of our own future resurrection.
Righteousness
/RY-chus-ness/TheologyBeing right with God — morally perfect and in proper relationship with Him.
Righteousness in Scripture has both a relational and moral dimension. The Hebrew tsedaqah describes conformity to a covenant standard — being "right" in relationship. The Greek dikaiosyne carries the same weight. A key debate in the Reformation was whether righteousness is "infused" (Catholics) or "imputed" (Protestants) — Martin Luther argued that Christ's righteousness is credited (imputed) to believers through faith, not earned through works.
"This righteousness is given through faith in Jesus Christ to all who believe."
— Romans 3:22
"Blessed are those who hunger and thirst for righteousness, for they will be filled."
— Matthew 5:6
Why it matters
Righteousness is not a standard you achieve — it is a gift you receive. The whole gospel hinges on this.
Regeneration
/reh-jen-er-AY-shun/SalvationBeing born again — the supernatural act of God giving a person new spiritual life.
Regeneration is the divine act by which the Holy Spirit imparts new spiritual life to a person who is spiritually dead in sin (Ephesians 2:1). The Greek palingenesia (palin — again, genesis — birth or origin) means "new birth" or "new creation." The more common New Testament term is anagennaō ("to beget again" or "to bear again"), used by Peter (1 Peter 1:3, 23) and closely related to the language Jesus uses with Nicodemus: "You must be born again" (or "born from above" — the Greek anothen can mean both) in John 3:3–8. Jesus compares regeneration to the wind — you cannot see it or control it, but you can see its effects. It is entirely the work of God, not a human decision or act. Regeneration precedes and enables repentance and faith — the Reformed view — or it accompanies them — the Arminian view — but all agree that it is supernatural, not natural. The result of regeneration is a new set of desires, a new capacity to respond to God, a new nature alongside the old. Paul calls it being "a new creation" (2 Corinthians 5:17) and a "new self" (Ephesians 4:24). The theologian John Murray described regeneration as "the implanting of the seed of God in the human heart" — the beginning of a life that will ultimately be completed in glorification.
"Jesus replied, "Very truly I tell you, no one can see the kingdom of God unless they are born again.""
— John 3:3
"Therefore, if anyone is in Christ, the new creation has come: the old has gone, the new is here!"
— 2 Corinthians 5:17
"For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God."
— 1 Peter 1:23
Why it matters
Regeneration means conversion is not self-improvement — it is resurrection. You cannot make yourself spiritually alive any more than a corpse can will itself back to life. What happens in the new birth is an act of God as radical as creation itself. This is why Jesus says you must be born again, not just try harder.
Sanctification
/sank-tih-fih-KAY-shun/SalvationThe ongoing process of being made holy.
Sanctification is the work of the Holy Spirit transforming a believer's character over time to reflect Christ more fully. It is distinct from justification (which is instantaneous and legal) — sanctification is progressive and experiential. The root word hagios means "holy" or "set apart." John Wesley's theology of sanctification, developed in the 18th century, emphasised the possibility of entire sanctification in this life.
"It is God's will that you should be sanctified: that you should avoid sexual immorality."
— 1 Thessalonians 4:3
"And we all, who with unveiled faces contemplate the Lord's glory, are being transformed into his image with ever-increasing glory."
— 2 Corinthians 3:18
Why it matters
Sanctification means salvation is not just about where you go when you die — it changes who you are right now.
Salvation
/sal-VAY-shun/SalvationBeing rescued from sin and its consequences — restored to right relationship with God.
Salvation is the comprehensive term for God's rescue of humanity from sin, death, and judgment. The Hebrew yeshua is also the name of Jesus (Yeshua) — meaning "God saves." The Greek soteria covers past (justification), present (sanctification), and future (glorification) dimensions. The ordo salutis (order of salvation) was systematised by Reformed theologians including Francis Turretin (1623–1687) to describe the logical sequence of salvation's application.
"Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved."
— Acts 4:12
"If you declare with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved."
— Romans 10:9
Why it matters
Salvation is not just about avoiding hell — it is about being restored to the relationship with God that humanity was always designed for.
Sin
/sin/TheologyMissing the mark — falling short of God's perfect standard.
The primary Greek word for sin, hamartia, is an archery term meaning "to miss the mark." The Hebrew chattath similarly means "to miss" or "to go wrong." Sin is not just moral failure — it is a fundamental rupture in the relationship between humanity and God. Augustine of Hippo (354–430 AD) developed the doctrine of original sin, arguing that Adam's sin corrupted all humanity. His Confessions (397 AD) remains one of the most honest explorations of sin's power ever written.
"For all have sinned and fall short of the glory of God."
— Romans 3:23
"If we claim to be without sin, we deceive ourselves and the truth is not in us."
— 1 John 1:8
Why it matters
Understanding sin is essential for understanding grace. The depth of the problem reveals the magnitude of the solution.
Shekinah
/shuh-KY-nah/ScriptureThe visible, glorious presence of God dwelling among his people.
Shekinah (from the Hebrew shakan — "to dwell") is a term used in later Jewish literature to describe the glorious, visible presence of God. Interestingly, the word itself does not appear in the Hebrew Bible, but it is widely used in the Targums (Aramaic paraphrases of Scripture) and rabbinic writings to describe what the Old Testament records in other terms: the cloud and fire that led Israel through the wilderness (Exodus 13:21), the glory that filled the Tabernacle (Exodus 40:34–35), the cloud that settled on Sinai (Exodus 24:16), and the glory that filled Solomon's Temple at its dedication (1 Kings 8:10–11). The Shekinah was so overwhelming that even Moses could not enter the Tabernacle when it descended, and the priests could not stand to minister in the Temple when it filled the house. The Shekinah's departure from the Temple — described in stages in Ezekiel 10–11 — signalled God's abandonment of Jerusalem before the Babylonian conquest. Its anticipated return was a key part of messianic expectation. The New Testament presents Jesus as the return of the Shekinah: John 1:14 says "we have seen his glory" — the Greek word for glory (doxa) consistently translates the Hebrew kabod, used for God's visible glory. The Transfiguration (Matthew 17:1–5), in which Jesus's face shone like the sun and the disciples fell on their faces, is a direct Shekinah event.
"Then the cloud covered the tent of meeting, and the glory of the Lord filled the tabernacle."
— Exodus 40:34
"The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth."
— John 1:14
"There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light."
— Matthew 17:2
Why it matters
The Shekinah is the Bible's answer to the question of where God is. He is not a distant deity to be searched for — he chose to come near, to fill a tent in the desert, and ultimately to take on human flesh. Every appearance of the Shekinah in the Old Testament is a preparation for the Incarnation.
Sabbath
/SAB-uth/ScriptureThe seventh day of rest — a sign of God's covenant with Israel and a picture of the rest found in Christ.
The Sabbath (Shabbat, from shavat — "to rest" or "to cease") is the seventh day of the week, set apart by God as holy from the very beginning of creation (Genesis 2:2–3). God himself rested on the seventh day — not from exhaustion, but as a completion, a ceasing from the work of creation. The Sabbath was enshrined in the Ten Commandments as the fourth commandment (Exodus 20:8–11) and given as a sign of the covenant between God and Israel (Exodus 31:13–17). In Israel, Sabbath observance was comprehensive: no work, no fire kindled, no commerce. It was a weekly reminder that Israel existed by grace, not productivity — that their identity rested in who God was, not what they could produce. The Sabbath year (every seventh year) allowed the land to rest, and the Year of Jubilee (every fiftieth year) returned land and liberated debts. Jesus famously clashed with the Pharisees over Sabbath regulations, declaring himself "Lord of the Sabbath" (Mark 2:28) and performing healings on the Sabbath day. Hebrews 4 develops the theology of Sabbath rest most fully: there remains a "Sabbath-rest for the people of God" — an entering into God's rest through faith in Christ. The Sabbath was the shadow; Christ is the substance (Colossians 2:16–17). Christians disagree on whether Sunday worship fulfils, replaces, or exists alongside the Sabbath — but all agree that the rest it pointed to is found in Christ.
"Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done."
— Genesis 2:3
""The Sabbath was made for man, not man for the Sabbath. So the Son of Man is Lord even of the Sabbath.""
— Mark 2:27–28
"There remains, then, a Sabbath-rest for the people of God; for anyone who enters God's rest also rests from their works, just as God did from his."
— Hebrews 4:9–10
Why it matters
The Sabbath is not primarily a rule about which day to observe — it is a statement about where human beings find their rest. The Pharisees turned it into a burden; Jesus revealed it as a gift. In him, the rest the Sabbath promised is finally and fully available.
Trinity
/TRIN-ih-tee/TheologyOne God existing as three distinct persons — Father, Son, and Holy Spirit.
The doctrine of the Trinity holds that God is one being in three co-equal, co-eternal persons. The word "Trinity" does not appear in the Bible but was coined by Tertullian of Carthage (c. 160–220 AD) in his work Against Praxeas. The doctrine was formally defined at the Council of Nicaea (325 AD) and expanded at the Council of Constantinople (381 AD), producing the Nicene Creed.
"Go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit."
— Matthew 28:19
"May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all."
— 2 Corinthians 13:14
Why it matters
The Trinity is not a puzzle to solve but a person to know. God is not a solitary being — He is eternally relational, and we are invited into that relationship.
Typology
/ty-POL-uh-jee/ScriptureThe way Old Testament people, events, and institutions foreshadow and find their fulfilment in Christ.
Typology is a method of biblical interpretation that identifies how Old Testament persons, events, institutions, and objects (called "types") prefigure or foreshadow their greater fulfilment in the New Testament (called "antitypes"). The Greek typos means "impression" or "stamp" — as a seal leaves its imprint in wax, the type leaves its pattern in the antitype. The New Testament authors use typological interpretation extensively and self-consciously. Paul calls Adam "a pattern (typos) of the one to come" (Romans 5:14) — Adam is the type, Christ is the antitype. He describes the wilderness experiences of Israel as "examples (typoi) written down for our instruction" (1 Corinthians 10:11). Peter connects Noah's flood to baptism (1 Peter 3:20–21). The entire letter to the Hebrews is an extended typological argument: the Levitical priesthood, the Tabernacle, the sacrificial system, and the Day of Atonement are all shadows (skia) of the heavenly realities fulfilled in Christ. Typology differs from allegory: allegory replaces the literal historical meaning of a text with a spiritual meaning (the Alexandrian school used this extensively); typology affirms the full historical reality of the type while also recognising its prospective, prophetic dimension. A type is a real historical event or person that God intentionally designed to point forward. This is why typology is not merely a reading strategy — it reveals the unity and intentionality of the whole Bible as the product of one divine author.
"Nevertheless, death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam, who is a pattern of the one to come."
— Romans 5:14
"The law is only a shadow of the good things that are coming — not the realities themselves."
— Hebrews 10:1
"These things happened to them as examples and were written down as warnings for us, on whom the culmination of the ages has come."
— 1 Corinthians 10:11
Why it matters
Typology is the interpretive key that unlocks the Old Testament. Without it, Leviticus is an ancient ritual manual. With it, Leviticus is a detailed portrait of the cross. The Ark of the Covenant, the manna, the Passover lamb, the mercy seat, the High Priest — every major Old Testament institution is a carefully designed preview of what Christ would accomplish. The Bible is one book with one story, and typology is how you see the connections.
Tabernacle
/TAB-er-nak-ul/ScriptureThe portable dwelling place of God among Israel in the wilderness — a physical picture of God living with his people.
The Tabernacle (mishkan, meaning "dwelling place" or "tent of meeting") was the portable sanctuary God commanded Moses to build in the wilderness after the Exodus (Exodus 25–40). It was an ornate tent structure divided into two sections: the Holy Place (containing the menorah, the table of showbread, and the altar of incense) and the Holy of Holies (containing the Ark of the Covenant), separated by a thick curtain. The entire structure was surrounded by a courtyard containing the bronze altar for burnt offerings and the bronze laver for washing. The Tabernacle was designed according to a heavenly pattern revealed to Moses on Sinai (Exodus 25:40; Hebrews 8:5) — every detail carried symbolic weight. God's glory — the Shekinah cloud — filled the Tabernacle when it was completed (Exodus 40:34). The Hebrew mishkan is closely related to the verb shakan — "to dwell." This same root appears in the Greek Septuagint as the basis for the word used in John 1:14: "the Word became flesh and dwelt (eskēnōsen — literally, 'tabernacled') among us." The Tabernacle was the physical anticipation of what the Incarnation fulfilled: God truly dwelling among his people. The New Testament letter to the Hebrews develops the Tabernacle typology in detail, showing that every element was a shadow of Christ's priestly ministry.
""Then have them make a sanctuary for me, and I will dwell among them.""
— Exodus 25:8
"The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth."
— John 1:14
"They serve at a sanctuary that is a copy and shadow of what is in heaven."
— Hebrews 8:5
Why it matters
The Tabernacle answers the deepest question in the Bible: can a holy God live with sinful people? Every detail — the sacrifices, the curtain, the priestly rituals — was God's way of saying "yes, but here is what it costs." Christ is the answer to what the Tabernacle was pointing toward all along.
Wrath of God
/rath of God/God's CharacterGod's holy, settled anger against sin — not a loss of control, but the consistent opposition of a perfectly good God to everything that destroys what he loves.
The wrath of God is one of the most misunderstood doctrines in Christianity — dismissed by some as a primitive projection onto God, and distorted by others into an image of divine rage indistinguishable from human anger at its worst. The biblical picture is neither. The Hebrew aph literally means "nose" or "nostril" — the flaring of the nose in anger — but when applied to God it describes a settled, consistent, holy reaction to sin and evil. The Greek orgē similarly describes a disposition rather than an outburst: not a sudden eruption but an abiding state. God's wrath is the necessary corollary of his love. A God who was indifferent to injustice, cruelty, and the destruction of his image-bearers would not be good — he would be negligent. The wrath of God in the Bible is always presented as the wrath of a holy, loving God who refuses to be neutral about evil. Romans 1:18 states that "the wrath of God is being revealed from heaven against all the godlessness and wickedness of people." John Stott, in The Cross of Christ (1986), argued that the primary problem the cross solves is the wrath of God — not because God needed to be appeased like a pagan deity, but because his own nature demands that sin be dealt with justly. The good news of the gospel is precisely that God himself, in Christ, bore the wrath that his own justice demanded — so that those who are in Christ stand not under wrath but under grace.
"The wrath of God is being revealed from heaven against all the godlessness and wickedness of people who suppress the truth by their wickedness."
— Romans 1:18
"Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on them."
— John 3:36
"Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him!"
— Romans 5:9
Why it matters
Remove the wrath of God and the cross becomes sentimental. If sin does not matter to God, if there is no consequence, no judgment, no holy opposition to evil — then why did Jesus have to die? The cross is only good news against the backdrop of what it rescued us from. The wrath is what makes the grace so radical.
Yahweh
/YAH-way/God's CharacterThe personal name of God — "I AM WHO I AM" — the self-existent, eternal one who keeps his covenant.
Yahweh is the personal name of the God of Israel, represented in Hebrew by four consonants: Yod, He, Waw, He (יהוה) — known as the Tetragrammaton. It appears over 6,800 times in the Hebrew Bible, making it by far the most common name for God in Scripture. The name was revealed to Moses at the burning bush: when Moses asked God his name, God replied "I AM WHO I AM" (Ehyeh asher ehyeh) and said "Say to the Israelites: YHWH has sent me to you" (Exodus 3:14–15). The name is derived from the Hebrew verb hayah — "to be" — and carries the sense of absolute, self-existent being: God does not derive his existence from anything outside himself. He simply is. Jewish tradition held the name so sacred that it was not pronounced aloud — readers would substitute Adonai ("Lord") when they came to it in the text. This is why most English Bibles print LORD in small capitals wherever YHWH appears. The actual pronunciation of YHWH was largely lost, though scholarly consensus favours "Yahweh." The name is not merely a label but a revelation of character: the God who is, who was, and who will be — the God who makes and keeps promises across generations. Every covenant God makes in Scripture is made under this name.
"God said to Moses, "I AM WHO I AM. This is what you are to say to the Israelites: 'I AM has sent me to you.'""
— Exodus 3:14
"Let them know that you, whose name is the Lord — that you alone are the Most High over all the earth."
— Psalm 83:18
"And he passed in front of Moses, proclaiming, "The Lord, the Lord, the compassionate and gracious God, slow to anger, abounding in love and faithfulness...""
— Exodus 34:6–7
Why it matters
When God reveals his personal name, he is not giving information — he is entering relationship. To know someone's name in the ancient world was to have access to them. God gave Israel his name so they could call on him. And in John 8:58, when Jesus says "before Abraham was, I AM," he is claiming that name for himself.
