Beside Still Waters is a nonfiction book by Gregg Easterbrook. In it he defends religion against its critics. He expounds a theory of religion and Christianity based on his reading of the Old and New Testaments, in which God is not an omnipotent omniscient being, but rather a limited and perhaps awesomely powerful being who learns and grows over time. In this way, Easterbrook seeks to explain the ravages and evil of the Old Testament God and to bring back Jesus's original teachings of charity and of love for God and for fellow humans.
