A third characteristic of God is goodness. If God weren't moral, ethical monotheism would be an oxymoron: A
God who is not good cannot demand goodness. Unlike all other gods believed in prior to monotheism, the biblical God rules by moral standards. Thus, in the Babylonian version of the flood story, the gods, led by Enlil, sent a flood to destroy mankind, saving only Utnapishtim and his wife - because Enlil personally liked Utnapishtim. It is an act of caprice, not morality. In the biblical story, God also sends a flood, saving only Noah and his wife and family. The stories are almost identical except for one overwhelming difference: The entire Hebrew story is animated by ethical/moral concerns. God brings the flood solely because people treat one another, not God, badly, and
God saves Noah solely because he was "the most righteous person in his generation."
