In the Christian story God descends to reascend. He comes down; down from the heights of absolute being into time and space, down into humanity; down further still, if embryologists are right, to recapitulate in the womb ancient and pre-human phases of life; down to the very roots and seabed of the Nature He has created. But He goes down to come up again and bring the whole ruined world 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 also disappear under the load before he incredibly straightens his back and marches off with the whole mass swaying on his shoulders.
C.S. Lewis (as published in Peace by Stephen J. Nichols, pp. 18-19)
