(1) In Zechariah 12:10, God speaks of the future return of Christ and says, ". . . They shall look upon me whom they have pierced, and they shall mourne for him, as one mourneth for his only son . . . ." This is spoken again in Revelation 1:7, which is clearly a reference to Christ Himself, but in Zechariah 12:10 GOD said, ". . . They shall look upon me whom they have pierced . . . ." The One that they pierced was Jesus Christ! So, in Zechariah 12:10, God is saying that He is Jesus Christ.
(2) In John 1:1, John 1:14, 1 John 1:1, and in 1 John 5:7, Jesus is called "the Word," and John 1:1 says that "the Word was God."
(3) Thomas referred to Jesus as "My Lord and my God" in John 20:28, and Jesus did not see the need to correct him.
(4) Isaiah 7:14 gives us the prophecy of the Virgin Birth of Christ and states that His name would be "Immanuel." Matthew 1:23 tells us that this word means "God with us."
(5) In Isaiah 9:6, Jesus is called "Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace." The Bible certainly would not say this about anyone less than God.
(6) In John 10:30, Jesus says, "I and my Father are one." Jesus is not a lesser god; He is ONE with the Father.
(7) Micah 5:2 tells us that Jesus is "from everlasting."
(8) In John 8:58, Jesus tells the Pharisees, "Before Abraham was, I am." He claimed to be the "I AM" of Exodus 3:14, which is God Almighty.
(9) Jesus allowed others to worship Him (John 9:38; Matt. 14:33; and Luke 24:52), which was forbidden, unless He was God (Rev. 22:9).
(10) Jesus forgave sins (Mark 2:5), which only God can do (Mark 2:7).
(11) The Lord Jesus Christ is omnipresent (Matt. 18:20; 28:20; II Cor. 13:14; I John 5:7). We know He is God because He is capable of being everywhere at once.
(12) Jesus is omniscient (Mark 11:2-6; Matt. 12:40). He is God because He knows all things.
(13) The Lord Jesus is also omnipotent (Rev. 19:6; Matt. 28:18). He has all power.
(14) According to John 1, 1 John 1, Colossians 1, and Hebrews 1, Jesus Christ is the Creator of Genesis 1!
(15) Jesus never sinned! Romans 3:23 says that ALL HAVE SINNED and come short of the glory of God, but Jesus did not sin (2 Cor. 5:21; 1 Peter 3:18). So Jesus had to be God.
Jesus also states "Neither be ye called masters, for ONE is your master, Christ"... Then God is referred to as the one master "You cannot serve two masters, you either love or hate the other... You cannot serve both God and mammon" meaning Jesus IS God, the ONE master (no humans or things).
JESUS IS GOD!
But God showed Himself in Jesus, who was in the flesh. "God is the word and the word became flesh" John.
John 1:1 - In the beginning was the Word, and the Word was with God, and the Word was God... 1:14 - And the Word became flesh and dwelt among us,
Isaiah 44:6 - (God is the Redeemer)
2 Peter 1:1 (Jesus is the Redeemer) - To those who have obtained like precious faith with us by the righteousness of our God and Savior Jesus Christ
Titus 2:13 - looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ
