Jesus answered, “You would have no power over me if it were not given to you from above…”  

This is profound.  Pilate would have no power  over Jesus at all, except that God the Father has allowed it, and Jesus Himself, surrendered to it.  I think it frightened Pilate to hear those words.  If he could have seen with spiritual eyes the 10, 000 angels guarding our Lord, Pilate would have dropped dead of fear on the spot.  But this is an eternal plan.  This is the fulfillment of prophecy, the final act of salvation.  The innocent, sinless, Lamb of God would die for the sins of all mankind and usher in the age of grace and forgiveness.
