In the Garden of Gethsemane, Jesus dies before he dies, and thereby readies himself for what awaits him. The next day, when Pilate threatens him with death, Jesus stands in a freedom and courage that can be understood only if we understand what happened to him in the garden. When Pilate says to him: “Don’t you know that I have power over you, power to take your life or to save it?” Jesus answers: “You have no power over me whatsoever. Nobody takes my life; I give it over freely.” Pilate is threatening a man who is already dead. No big threat. Jesus had already undergone the agonia. In great anguish, he had given his life over freely the night before, and so he is ready for whatever awaits him.
