Jesus responded to the Jews rejection of him as their Messiah by first letting them know that they would be jusged for their choice (John 5:22) and then, explained to them that there would come a day when everyone would be resurrected from the dead, but rather than entering into the presence of God and living with him for eternity, those who rejected Jesus would spend eternity in hell (John 5:29). Jesus intentionally made a point of declaring the truth about God’s judgment early in his ministry, and also talked about it often, so that no one could say, I didn’t know about that. Comparing God’s judgment to a legal case in which each person would be charged with some offence, Jesus said, “Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom you trust” (John 5:45). Jesus said this because his “listeners prided themselves on their attachment to Moses, the great lawgiver. So it was an unexpected thrust for Jesus to say Moses himself would accuse them before God” (note on John 5:45).
Thinking about the evidence required to convict someone of a crime in a court of law, Jesus identified four witnesses that could testify that he was in fact the Jews’ Messiah. The first witness Jesus called to their minds was John the Baptist (John 5:33). The Jews were familiar with John’s message and many saw him baptize Jesus in the Jordan river (Matthew 3:16). During his first encounter with Jesus, John stated, “Behold the Lamb of God, which taketh away the sin of the world” (John 1:29). Jesus told the Jews, “But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me” (John 5:36). Jesus was referring to his works of salvation. The Messiah’s mission was to save God’s people and Jesus intended to finish that assignment through his death and resurrection. Ultimately, there was no better way for Jesus to prove he was who he said was than to resurrect himself from the dead. If that wasn’t enough, Jesus added that God himself had testified to his identity (Matthew 3:17) and the Scriptures also testified of him (John 5:39).
