Evil exists in all of us from the very beginning. Enemies of God and man. In Genesis because of evil, God chooses to destroy the world except for Noah, who is considered blameless and his family, David is on the run from Absalom and his followers. In the Luke passage everything changes, Jesus tells us to"love our enemies and do good to those who hate you." He then proceeds to tells us how, to who and the benefits of doing so.
