Is Jesus God? — His followers declared Him to be God.
John reiterates the concept of Jesus’ deity: “The Word [Jesus] 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 with His own blood? Jesus Christ. And this same verse 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 2:13 encourages 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 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. Beyond these, there are many other passages of Scripture that argue for Jesus being God.
Is Jesus God? — The reason Jesus must be God.
The most important reason that Jesus must 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.
Is Jesus God? Yes. Jesus declared Himself to be God. His followers believed Him to be God. The provision of salvation only works if Jesus is God. Jesus is God incarnate, the eternal Alpha and Omega (Revelation 1:8; 22:13), and God our Savior (2 Peter 1:1).
