“He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.” Acts 17:31
Usually in church we are called to believe in our hearts something that we can’t see with our eyes. But there is one case where God encourages us to examine something we can see with the logic of our minds – the resurrection. God has “furnished proof” that Jesus is the judge of all mankind by raising Him from the dead.
In John 2 Jesus clears the temple and the religious leaders ask, “What sign do you show us as your authority for doing these things?” (John 2:18) The only person on earth that might have authority to move temple furniture around was the high priest. Outside of him, only God himself would have that kind of authority. “Who do you think you are?” is what they’re asking. Jesus answered, “Destroy this temple, and in three days I will raise it up.” (John 2:19) The sign He gave of His authority was the resurrection. In Matthew 12 again He is asked for a sign but replies that no sign will be given except the sign of His death and resurrection as prefigured in the story of Jonah. (Matthew 12:39-40)
Paul says that all of Christianity hinges on the actual, historical resurrection of Jesus. “If Christ has not been raised, your faith is futile; you are still in your sins… if only for this life we have hope in Christ, we are to be pitied more than all men.” (1Corinthians 15:17-19) I’ve heard people say that they’d be a Christian “even if it wasn’t true.” Paul wouldn’t be. He’s only in if it’s true and to him it’s true because of a historical proof that God gave. Paul didn’t believe in Jesus because he was afraid he’d go to hell if he didn’t, and he didn’t ultimately believe because of the subjective encounter he had on the road to Damascus. He believed because it was the truth; not just his truth, but everyone’s. The evidence is the resurrection.
