Around Abraham's rackety grandson Jacob are woven several engaging tales of outrageous cheating and deceit, and they culminate in an all-night wrestling match with a mysterious stranger who overcomes Jacob and is able to give him another name, Israel, meaning 'He who strives with God'. Out of that fight in the darkness, with one who revealed the power of God and was God, began the generations of the Children of Israel. Few peoples united by a religion have proclaimed by their very name that they struggle against the one whom they worship. The relationship of God with Israel is intense, personal, conflicted. Those who follow Israel and the religions which spring from his wrestling match that night are being told that even through their harshest and most wretched experiences of fighting with those they love most deeply, they are being given some glimpse of how they relate to God.
