Christianity stands or falls on a single question: who is Jesus of Nazareth? If He is a prophet, a teacher, or a moral example, then Christianity is one religion among many and its central act of worship is idolatry. If He is God in human flesh, then every other question is downstream of that one.

The case for His deity is not built on one or two isolated proof-texts that require special pleading. It is built on the convergence of several independent lines of evidence — claims Jesus made, titles He received, acts only God can perform, worship He accepted without rebuke, and Old Testament passages about YHWH applied directly to Him by inspired apostles. Any one of these could be argued about. Together they form a case that cannot be dismantled by disputing a single verse.

This post lays out those lines of argument. The rest of the series walks the canon from Genesis to Revelation and shows where each one comes from.

The Ego Eimi (I AM) Statements of Jesus

The absolute, predicate-less use of ἐγώ εἰμί (egō eimi, "I AM") by Jesus in the Gospel of John is a sustained, deliberate pattern of divine self-identification. Beyond the seven famous "I AM + predicate" statements (I AM the bread of life, the light of the world, the door, the good shepherd, the resurrection and the life, the way/truth/life, the vine), Jesus uses the absolute form — with no predicate — in contexts that evoke the divine name:

John 18:6 is particularly instructive: when Jesus declared "I AM" to the soldiers who came to arrest Him, "they drew back and fell to the ground." This is a theophanic response — the involuntary falling that characterizes encounters with the divine presence (cf. Ezekiel 1:28; Daniel 8:17; Revelation 1:17). His mere utterance of the divine name caused the power of the Most High to manifest, confirming the nature of the declaration.

Jesus as the Object of Worship

Throughout the NT, Jesus receives the worship that in the OT belonged exclusively to YHWH. In a culture and religious framework (Judaism) where any worship of a creature was the gravest possible sin, the consistent acceptance of worship by Jesus is a decisive indicator of His divine status:

When angels (Revelation 22:8–9; Acts 10:25–26) and righteous men (Peter in Acts 10:25–26) refused worship, Jesus consistently accepted it. This pattern is incoherent unless Jesus is God.

Jesus Forgiving Sins: A Divine Prerogative

Forgiveness of sins in the OT is exclusively YHWH's prerogative:

• Isaiah 43:25: "I, even I, am the one who wipes out your transgressions for My own sake"
• Psalm 103:3: "Who pardons all your iniquities" (YHWH)
• Micah 7:18: "Who is a God like You, who pardons iniquity and passes over the rebellious act"

Jesus directly, authoritatively forgives sins in His own name — not as a conduit or mediator interceding with God, but as One who Himself has the authority to forgive:

• Mark 2:5: "Son, your sins are forgiven"
• Luke 7:48: "Your sins have been forgiven"
• John 8:11: "Neither do I condemn you; go"

The objection of the scribes — "Who can forgive sins but God alone?" (Mark 2:7) — was theologically correct. Their error was not in their understanding of the divine prerogative of forgiveness; their error was in not recognizing that God was standing before them.

Jesus as Universal Judge

In the OT, YHWH is the universal Judge of all mankind:

• Genesis 18:25: "Shall not the Judge of all the earth deal justly?"
• Psalm 96:13: "He is coming to judge the earth; He will judge the world with righteousness"
• Ecclesiastes 12:14: "For God will bring every act to judgment"

The NT transfers this exclusive divine prerogative of universal judgment to Jesus Christ:

• John 5:22: "For not even the Father judges anyone, but He has given all judgment to the Son"
• Acts 17:31: "He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed"
• 2 Timothy 4:1: "Christ Jesus, who is to judge the living and the dead"
• Revelation 20:11–13: The great white throne judgment — presided over by Christ
• Matthew 25:31–46: The Son of Man separates all nations as a shepherd separates sheep from goats

Only God can judge all humanity perfectly, with complete knowledge, absolute justice, and sovereign authority. The NT's consistent assignment of universal judgment to Jesus is a declaration of His divine nature.

Jesus as Creator and Sustainer of All Things

Creation is exclusively God's act in the OT:

• Genesis 1:1: "In the beginning God created the heavens and the earth"
• Isaiah 44:24: "Thus says the LORD, your Redeemer, and the one who formed you from the womb: 'I, the LORD, am the maker of all things, stretching out the heavens by Myself and spreading out the earth all alone'"

The NT attributes creation to Jesus Christ without qualification:

• John 1:3: "All things came into being through Him, and apart from Him not even one thing came into being"
• Colossians 1:16: "For by Him all things were created...all things have been created through Him and for Him"
• Hebrews 1:2: "through whom also He made the world"
• Hebrews 1:10: "YOU, LORD, IN THE BEGINNING LAID THE FOUNDATION OF THE EARTH" (quoting Psalm 102:25, originally addressed to YHWH, now applied to the Son)
• 1 Corinthians 8:6: "one Lord, Jesus Christ, by whom are all things, and we exist through Him"

The sustained, multi-author, consistent NT attribution of the entire act of creation to Jesus is one of the strongest possible affirmations of His full deity.

The Granville Sharp Rule

The Granville Sharp Rule (named after the English abolitionist and Greek scholar Granville Sharp, 1735–1813) is a Greek grammatical rule that states: when two singular personal nouns (not proper names) in the same case are connected by καί (kai, "and") with the article preceding only the first noun, both nouns refer to the same person.

This rule applies in at least two key NT passages affirming the deity of Christ:

Titus 2:13 — "our great God and Savior, Christ Jesus" (τοῦ μεγάλου θεοῦ καὶ σωτῆρος ἡμῶν Χριστοῦ Ἰησοῦ) — One article tou governs both theou (God) and sōtēros (Savior); both refer to Christ Jesus.

2 Peter 1:1 — "our God and Savior, Jesus Christ" (τοῦ θεοῦ ἡμῶν καὶ σωτῆρος Ἰησοῦ Χριστοῦ) — Same construction; both "God" and "Savior" refer to Jesus Christ.

Granville Sharp himself wrote: "The rule is absolute and admits of no exception, when the nouns are of the same case and refer to individuals" (Remarks on the Uses of the Definitive Article in the Greek Text of the New Testament, 1798). Sharp's rule has been confirmed by subsequent Greek grammarians, including A. T. Robertson ^[1], Daniel Wallace ^[2], and others.

YHWH Titles Applied to Jesus

One of the most powerful arguments for the deity of Christ is the systematic application of OT YHWH titles and attributes to Jesus in the NT:

This systematic, multi-author, cross-Testament pattern is not a coincidence — it is the inspired declaration of the full deity of Jesus Christ, woven through the entire canon of Scripture.

Additional Cumulative Evidence

A handful of further data points, while individually more circumstantial than the arguments above, add further weight to the cumulative case:

• Two YHWH figures in a single verse. Genesis 19:24 reads, "Then the LORD [YHWH] rained on Sodom and Gomorrah brimstone and fire from the LORD [YHWH] out of heaven" — one YHWH acting on the earth and another YHWH "out of heaven," a textual pattern also seen in Zechariah 2:8–11 and Amos 4:10–11, where YHWH speaks of another whom He also calls God. Second Temple Jewish literature preserves a "two powers in heaven" tradition reflecting an awareness of this plurality within monotheism, well before it was applied to the risen Jesus and subsequently rejected by rabbinic Judaism ^[3].
• "Most High" applied to Jesus. The title "Most High" (ʿElyôn), used of YHWH over all the earth (Psalm 83:18; 97:9; Isaiah 54:5), is applied to Jesus by the way the New Testament identifies Him with YHWH's exclusive titles and prerogatives throughout the YHWH-titles table above.
• Salvation in no other name. Acts 4:12 states there is salvation in no name but Jesus' — striking, given the Old Testament's insistence that YHWH alone is Savior (Isaiah 43:11; 45:21).
• Jesus as the God who commissioned Paul. On the Damascus road, Paul encountered the risen Jesus, who commissioned him directly (Acts 22:8–10, 14; 26:16) — language elsewhere reserved for direct divine commissioning of a prophet.
