If we read the Bible, there is no doubt that it tells us that Jesus Christ is God.  He has many titles, abilities, and duties, but we must recognize Him as not only the Son of God, but God the Son, the second person of the trinity (the triune Godhead).  Know these verses and be able to refer to them or quote them when people challenge Jesus' deity.

John 1:1 and 14  "In the beginning was the Word, and the Word was with God, and the Word was God . . . . And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth."

John 20:26-28  "And after eight days His disciples were again inside, and Thomas with them.  Jesus came, the doors being shut, and stood in the midst, and said, 'Peace to you!'  Then He said to Thomas, 'Reach your finger here, and look at My hands; and reach your hand here, and put it into My side.  Do not be unbelieving, but believing.'  And Thomas answered and said to Him, 'My Lord and my God!'"

Matthew 4:5-7  ""Then the devil took Him up into the holy city, set Him on the pinnacle of the temple, and said to Him, 'If You are the Son of God, throw Yourself down.  For it is written: ‘He shall give His angels charge over you,’ and, ‘In their hands they shall bear you up, Lest you dash your foot against a stone.’  Jesus said to him, 'It is written again, ‘You shall not tempt the LORD your God.’"

Acts 20:28  "Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood."

Romans 9:3-5  "For I could wish that I myself were accursed from Christ for my brethren, my countrymen according to the flesh, who are Israelites, to whom pertain the adoption, the glory, the covenants, the giving of the law, the service of God, and the promises; of whom are the fathers and from whom, according to the flesh, Christ came, who is over all, the eternally blessed God. Amen."

Titus 2:11-14  "For the grace of God that brings salvation has appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age, looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ, who gave Himself for us, that He might redeem us from every lawless deed and purify for Himself His own special people, zealous for good works."

Hebrews 1:8  "But to the Son He says: 'Your throne, O God, is forever and ever; A scepter of righteousness is the scepter of Your kingdom.'"

1 John 5:20  "And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life."
