Even if the dialogue (between God and Abraham in Genesis 18:22-33) is ultimately an example of divine pedagogy, must we rule out the possibility that human communicative act make a difference to God? I Think not. For what Abraham learns is "the kind of response expected fro YHWH's elect so that the divine blessing may be mediated to the nations." Abraham does not argue and win, but argues and learns: about God and how to participate rightly in the drama of redemption. It is not that God needs humans to do what is right. It is rather that God has decided not to execute his plan apart from human participation in it, just as he has decided not to be God without humanity.

A final detail in Jesus' death scene deserves comment. Just before he "breathed his last" (exepneusen), he cried out in a "great voice" (megalen phonen). The content of Jesus' utterance is not mentioned, but that is because it is beside the point: only one who still had life and energy could shout so vigorously. Jesus does not submit to death but permits it. Truly, no one takes Jesus' life from him (Jn. 10:18). Perhaps this is why the centurion, when he saw "that he thus breathed his last," confessed Jesus as the Son of God.
