The ascension is the vindication of Jesus and His claims. At His trial before the Jewish council as told in Luke’s gospel, Jesus is asked whether He is the Christ, God’s promised king. He replies: ‘If I tell you, you will not believe me, and if I asked you, you would not answer. But from now on, the Son of Man will be seated at the right hand of the mighty God.’ They all asked, ‘Are you then the Son of God?’ He replied, ‘You say that I am’ (Luke 22:66-71). Jesus is alluding to Daniel 7 and His ascension. The verdict of humanity against Jesus is ‘blasphemy’ (22:71). Humanity rejects the claim of Jesus to be the king of the world and Son of God. Instead we condemn Him. We all do this as we refuse to live our lives under His lordship. We reject His claims and so we reject His rule. The verdict of the Jewish leaders was not an unusually bad day in the history of humanity. It was a typical day. The only difference was they had the Son of God standing before them, seemingly at their mercy. This is where our rebellion ends, with the condemnation of God’s Son.
But, just as Jesus predicted, the verdict of humanity is overturned through the ascension by the heavenly court of appeal. The heavenly scene which Jesus enters on the clouds is a courtroom scene. ‘The court was seated and the books were opened,’ we are told in Daniel 7:10. Humanity rejected the claims of Jesus and condemned Him to death. Now the heavenly court strips the kingdoms of earth of their power and gives that power forever to Jesus. Jesus is vindicated.
