The Aseity of God — Exodus 3:14

At the burning bush God names himself in Exod 3:14: "I AM WHO I AM." The divine name discloses God's self-existence — he depends on nothing outside himself for his being.

Thomas Aquinas — Summa Theologiae. Augustine — Confessions. Herman Bavinck — Reformed Dogmatics.

Jesus invokes this very name in John 8:58, "before Abraham was, I am," claiming divine self-existence for himself. The God who simply is stands behind the sovereignty of Eph 1:11.
