Moses angers the Lord with his multiple excuses as to why he can’t do what God is asking him to do. The bush is burning as Moses resists, but God in his mercy does not cancel the call yet provides a spokesman for Moses, his brother Aaron, who will later give Moses the debacle of the golden calf worship. Moses learns that doing God’s work requires a shift from the ‘super me’ to the Great I AM, and that being on mission for God requires a condition of total obedience to the covenant established with Abraham.
