Yes — Jesus is God the Son, the second person of the Trinity, fully divine and fully human. The biblical evidence: explicit statements (John 1:1, 20:28, Hebrews 1:8), his own 'I AM' claims (identifying himself with the divine name of Exodus 3:14), the worship he accepted, and the divine attributes he demonstrated. C.S. Lewis's trilemma: Lord, liar, or lunatic — and the evidence rules out liar and lunatic. 98/100 Christ-Centered.
John 1:1-3 — "In the beginning was the Word, and the Word was with God, and the Word was God. Through him all things were made." John 1:14 — "The Word became flesh and made his dwelling among us." Jesus is the Word made flesh — God incarnate. John 20:28 — Thomas sees the risen Jesus and declares "My Lord and my God!" Jesus does not correct him. The most explicit affirmation of Jesus's deity in the Gospels, made in his presence with his approval. Hebrews 1:8 — The Father addresses the Son: "Your throne, O God, will last forever." Colossians 2:9 — "In Christ all the fullness of the Deity lives in bodily form."
The "I AM" statements in John deliberately echo the divine name revealed to Moses in Exodus 3:14 ("I AM WHO I AM"). John 8:58 — "Before Abraham was born, I AM!" — the Jews picked up stones to stone him for blasphemy (v.59). John 10:30 — "I and the Father are one." — again attempted stoning (v.31-33). Jesus accepted worship (Matthew 28:9, John 20:28), forgave sins on his own authority (Mark 2:5-7 — the scribes correctly identified this as something only God can do), and claimed authority to judge all humanity.
A man who claimed to be God, to forgive sins, and to judge all humanity at the end of time was either: telling the truth (Lord), a deluded megalomaniac (lunatic), or a deliberate deceiver (liar). The quality of his life and teaching rules out lunatic and liar for any fair-minded observer. Lord is the only remaining option — which is why his contemporaries either worshipped him or executed him, but no one called him merely a good teacher.
