The Aseity of God

Aseity refers to God’s self-existence (a—from, se—oneself). God exists ‘from himself.’ God owes his existence and completeness as God to nothing outside himself. . . .

God’s act of creation was not constrained by anything outside him, nor was the inner impulse to create owing to deficiency or defect. . . . God does not need us or anything else outside himself to be God or to be happy. Creation does not complete God.
