How can the deity of Jesus be proven? All four gospel writers have an answer to this question, but let us ask just one of them — Matthew — to answer.
Matthew proved Jesus is the divine Messiah by showing the Lord’s self-sacrificial love and service to others. Matthew said representatives of John, who baptized Jesus in the Jordan, came asking, “Are you the expected one, or should we look for someone else?” (Matthew 11:3 NASB). Jesus did not tell them of his power. He did not announce his divinity as others have done. Jesus proved his deity through examples of sacrifice and service.
Jesus said, “Go and report to John what you hear and see: the blind receive sight and the lame walk, the lepers are cleansed and the deaf hear, the dead are raised up, and the poor have the gospel preached to them; ‘And blessed is he who does not take offense at me’” (Matthew 11:4-6).
Jesus provided evidence of his divinity. What Jesus told John’s representatives was recorded in the Old Testament as Isaiah proclaimed the coming Messiah, “Say to those with anxious heart, ‘Take courage, fear not. Behold, your God will come with vengeance; the recompense of God will come, but He will save you.’ Then the eyes of the blind will be opened and the ears of the deaf will be unstopped. Then the lame will leap like a deer, and the tongue of the mute will shout for joy. For waters will break forth in the wilderness and streams in the Arabah” (Isaiah 35:4-6).
Matthew addressed Jesus as “Immanuel” numerous times in his gospel, thus proving the deity of Jesus. In Matthew 1:23; 2:11; 8:2; and 9:18, Matthew proved Jesus divine by not only calling him by this divine name, but also by showing how Jesus accepted worship and how people bowed before him. Jews were expressly forbidden to bow or worship anyone except God (Exodus 20:5).
Matthew proved Jesus was the son of God by showing how people made the confession of faith admitting that divinity. Peter told Jesus and the disciples that the Lord was the son of God (Matthew 16:16). In Matthew 28:19, Jesus himself told his disciples he was the son of God when he commanded them, “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit.”
Therefore, in at least these three ways in only one of the gospels Jesus was proved to be the Christ, the son of God. If you have not believed the proof, you should believe and obey Jesus today (Matthew 28:18-20).
