46. Doctrine of God - Aseity

The aseity of God is His attribute of independent self-existence. God is the uncaused Cause, the uncreated Creator. He is the source of all things, the One who originated everything and who sustains everything that exists. The aseity of God means that He is the One in whom all other things find their source, existence, and continuance. He is the ever-present Power that sustains all life. There is no other source of life and none other like Him: “For I am God, and there is no other; I am God, and there is none like Me” (Isaiah 46:9).
God is the eternally self-existent Being who always was and always will be. The aseity of God is related to His complete independence. God has no need. He is complete in and of Himself and always has been. God did not create man because He was lonely or because He needed to create. He is and always has been complete and self-sufficient in and of Himself.
He did not have a beginning. He has always been. God is unchangeable (Malachi 3:6; James 1:17), always the same yesterday, today, and forever. He will be what He is forever. All of God’s attributes—His love, power, wisdom, etc.—are eternal and unchanging. They are as they have always been and will never be any different.
God’s aseity assures us that His autonomy is absolute. He alone decides what to do, and nothing can ever thwart His purpose to keep His promises. What He promises to do, He will do. What He predicts will come to pass. God is outside time, space and matter.
