Jesus is never recorded in the Bible as saying the precise words, “I am God.” That does not mean, however, that He did not proclaim that He is God. Take for example Jesus’ words in John 10:30, “I and the Father are one.” We need only to look at the Jews’ reaction to His statement to know He was claiming to be God. They tried to stone Him for this very reason. “… you, a mere man, claim to be God” (John 10:33). The Jews understood exactly what Jesus was claiming—deity. Notice that Jesus does not deny His claim to be God. When Jesus declared, “I and the Father are one” (John 10:30), He was saying that He and the Father are of one nature and essence. John 8:58 is another example. Jesus declared, “I tell you the truth, before Abraham was born, I am!” The response of the Jews who heard this statement was to take up stones to kill Him for blasphemy, as the Mosaic Law commanded them to do (Leviticus 24:15).
John reiterates the concept of Jesus’ deity: “the Word was God” and “the Word became flesh” (John 1:1, 14). These verses clearly indicate that Jesus is God in the flesh. Acts 20:28 tells us, “Be shepherds of the church of God, which he bought with his own blood.” Who bought the church—the church of God—with His own blood? Jesus Christ. Acts 20:28 declares that God purchased His church with His own blood. Therefore, Jesus is God!
Thomas the disciple declared concerning Jesus, “My Lord and my God” (John 20:28). Jesus does not correct him. Titus 2:13encourages us to wait for the coming of our God and Savior, Jesus Christ (see also 2 Peter 1:1). In Hebrews 1:8, the Father declares of Jesus, “But about the Son He says, ’Your throne, O God, will last forever and ever, and righteousness will be the scepter of your kingdom.’” The Father refers to Jesus as “O God” indicating that Jesus is indeed God.
In Revelation, an angel instructed the apostle John to only worship God (Revelation 19:10). Several times in Scripture Jesus receives worship (Matthew 2:11, 14:33, 28:9, 17; Luke 24:52; John 9:38). He never rebukes people for worshiping Him. If Jesus were not God, He would have told people to not worship Him, just as the angel in Revelation did. There are many other verses and passages of Scripture that argue for Jesus’ deity.
The most important reason that Jesus has to be God is that if He is not God, His death would not have been sufficient to pay the penalty for the sins of the world (1 John 2:2). A created being, which Jesus would be if He were not God, could not pay the infinite penalty required for sin against an infinite God. Only God could pay such an infinite penalty. Only God could take on the sins of the world (2 Corinthians 5:21), die, and be resurrected, proving His victory over sin and death.
