"After the knowledge of God had been universally lost or obscured, one man from the whole earth (Abraham) is picked out. He is separated (miserably enough, we may suppose) from his natural surroundings, sent into a strange country, and made the ancestor of a nation who are to carry the knowledge of the true God. Within this nation there is further selection: some die in the desert, some remain behind in Babylon. There is further selection still. The process grows narrower and narrower, sharpens at last into one small bright point like the head of a spear. It is a Jewish girl at her prayers. All humanity (so far as concerns its redemption) has narrowed to that." - C.S. Lewis
