The Immutability of God

The Immutability of God is a necessary concomitant of His aseity. It is that perfection of God by which He is devoid of all change, not only in His Being, but also in His perfections, and in His purposes and promises. In virtue of this attribute He is exalted above all becoming, and is free from all accession or diminution and from all growth or decay in His Being or perfections. His knowledge and plans, His moral principles and volitions remain forever the same. Even reason teaches us that no change is possible in God, since a change is either for better or for worse. But in God, as the absolute Perfection, improvement and deterioration are both equally impossible. This immutability of God is clearly taught in such passages of Scripture as Exodus 3:14; Psalm 102:26-28; Isaiah 41:4; 48:12; Malachi 3:6; Romans 1:23; Hebrews 1:11, 12; James 1:17. At the same time there are many passages of Scripture which seem to ascribe change to God. Did not He who dwelleth in eternity pass on to the creation of the world, become incarnate in Christ, and in the Holy Spirit take up His abode in the Church? Is He not represented as revealing and hiding Himself, as coming and going, as repenting and changing His intention, and as dealing differently with man before and after conversion? Cf. Exodus 32:10-14; Jonah 3:10; Proverbs 11:20; 12:22; Psalm 18:26, 27.

The objection here implied is based to a certain extent on misunderstanding. The divine immutability should not be understood as implying immobility, as if there were no movement in God. It is even customary in theology to speak of God as actus purus, a God who is always in action. The Bible teaches us that God enters into manifold relations with man and, as it were, lives their life with them. There is change round about Him, change in the relations of men to Him, but there is no change in His Being, His attributes, His purpose, His motives of action, or His promises. The purpose to create was eternal with Him, and there was no change in Him when this purpose was realized by a single eternal act of His will. The incarnation brought no change in the Being or perfections of God, nor in His purpose, for it was His eternal good pleasure to send the Son of His love into the world. And if Scripture speaks of His repenting, changing His intention, and altering His relation to sinners when they repent, we should remember that this is only an anthropopathic way of speaking. In reality the change is not in God, but in man and in man's relations to God. It is important to maintain the immutability of God over against the Pelagian and Arminian doctrine that God is subject to change, not indeed in His Being, but in His knowledge and will, so that His decisions are to a great extent dependent on the actions of man; over against the pantheistic notion that God is an eternal becoming rather than an absolute Being, and that the unconscious Absolute is gradually developing into conscious personality in man; and over against the present tendency of some to speak of a finite, struggling, and gradually growing God.
