The resurrection effectively reversed the charges against Jesus and confirmed his mission. We thus see that if he had saved his life at the cost of his proclaiming the divine lordship, he would have actually made himself independent of God and put himself in equality with him. ‘Whoever would save his life will lose it’ (Mark 8:35 par.). This was true of Jesus himself. He could not be the Son of God by an unlimited duration of his finite existence. No finite being can be one with God in infinite reality. Only as he let his creaturely existence be consumed in service to his mission could Jesus as a creature be one with God. As he did not cling to his life but chose to accept the ambivalence that his mission meant for his person, with all its consequences, he showed himself, from the standpoint of he Easter event, to be obedient to his mission (Rom. 5:19, Heb. 5:8). This obedience led him into the situation of extreme separation from God and His immortality, into the dereliction of the cross. The remoteness from God on the cross was the climax of his self-distinction from the Father. Rightly then, we may say that the crucifixion was integral to his earthly existence.
