In the Gospels, we see Jesus consistently reversing what should be absolutely irreversible. He heals lepers. He restores sight to the blind. He commands a dead guy to come out of a tomb...and the guy obeys him! Jesus even restore the cut-off ear of the servant of the high priest on the night he was arrested. Despite all of that, his followers struggled with doubt and skepticism that he had actually risen from the dead. But once they were convinced...once they saw him with their own eyes (and ate with him); they became evangelists and together, with the Holy Spirit, turned the world upside down. The resurrection is that important.
