In the Christian story God descends . . . he comes down from the heights of absolute being into time and space, down into humanity, down further still . . . to the very roots and sea bed of the nature he has created. But he goes down to come up again and bring the whole ruined creation up with him. One has the picture of a strong man stooping lower and lower to get himself underneath some great complicated burden. He must stoop in order to lift, he must almost disappear under the load before he incredibly straightens his back and marches off with the whole lot swaying on his shoulders.
