In Exodus 3, we read how God announced his name to Moses as “I AM WHO I AM” (v. 14)—a phrase of which “Yahweh” (Jehovah, “the LORD”) is in effect a shortened form (v. 15). This name is not a description of God, but simply a declaration of his self-existence and his eternal changelessness; a reminder to mankind that he has life in himself, and that what he is now, he is eternally.
