Ephesians 1
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. Aquinas built his metaphysics on this text, naming God ipsum esse subsistens, being itself. Augustine contrasted God's unchanging 'I AM' with the mutable creature that merely becomes. Bavinck made aseity the root of all the incommunicable attributes. 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.
The Sovereignty of God in Election — Ephesians 1:3-14
Eph 1:3-14 is one long sentence of praise: God "chose us in him before the foundation of the world," "predestined us for adoption," and works "all things according to the counsel of his will." Election is "to the praise of his glory." Calvin read this doxology as the warrant for the doctrine of predestination, and Augustine grounded adoption in unmerited grace. Barth reoriented the whole around election in Christ, 'in him' being the key phrase. The phrase "the counsel of his will" connects to the potter's freedom in Rom 9:18-21 and to the calling of Rom 8:29-30. Sovereign grace and assured glory are two ends of one purpose.
