God gave his Name, Yahweh (i.e. "I AM"), to Moses, so we know what He did -- created and redeemed us and that we can proclaim His name to all nations. We can personally call on God using His name, "Hallowed by Thy Name", because God is our true Father, we are his true children. Jesus declared his divinity using the seven "I AM" statements in John. We also learn -- the difference between "LORD" and "Lord"; the meaning of Adonai; and "The Angel of the Lord".
