IMMUTABILITY is one of the Divine perfections which is not sufficiently pondered. It is one of the excellencies of the Creator which distinguishes Him from all His creatures. God is perpetually the same: subject to no change in His being, attributes, or determinations. Therefore God is compared to a rock (Deut 32:4, etc.) which remains immovable, when the entire ocean surrounding it is continually in a fluctuating state; even so, though all creatures are subject to change, God is immutable. Because God has no beginning and no ending, He can know no change. He is everlastingly “the Father of lights, with whom is no variableness, neither shadow of turning” (James 1:17).
First, GOD IS IMMUTABLE IN HIS ESSENCE.
His nature and being are infinite, and so, subject to no mutations. There never was a time when He was not; there never will come a time when He shall cease to be. God has neither evolved, grown, nor improved. All that He is today, He has ever been, and ever will be. “I am the LORD, I change not” (Mal 3:6) is His own unqualified affirmation. He cannot change for the better, for He is already perfect; and being perfect, He cannot change for the worse. Altogether unaffected by anything out-side Himself, improvement or deterioration is impossible. He is perpetually the same. He only can say, “I AM THAT I AM” (Exo 3:14). He is altogether uninfluenced by the flight of time. There is no wrinkle upon the brow of eternity. Therefore His power can never diminish nor His glory ever fade.
Secondly, GOD IS IMMUTABLE IN HIS ATTRIBUTES.
Whatever the attributes of God were before the universe was called into existence, they are precisely the same now, and will remain so for ever. Necessarily so; for they are the very perfections, the essential qualities of His being. Seniper ideni (always the same) is written across every one of them. His power is unabated, His wisdom undiminished, His holiness unsullied. The attributes of God can no more change than Deity can cease to be. His veracity is immutable, for His Word is “for ever.. settled in heaven” (Psa 119:89). His love is eternal: “I have loved thee with an everlasting love” (Jer 31:3) and “Having loved His own which were in the world, He loved them unto the end” (John 13:1). His mercy ceases not, for it is “everlasting” (Psa 100:5).
Thirdly, GOD IS IMMUTABLE IN HIS COUNSEL.
His will never varies. Perhaps some are ready to object that we ought to read the following: “And it repented the LORD that He had made man” (Gen 6:6). Our first reply is, Then do the Scriptures contradict themselves? No, that cannot be. Numbers 23:19 is plain enough: “God is not a man, that He should lie; neither the son of man, that He should repent.” So also in 1 Samuel 15:29, “The Strength of Israel will not lie nor repent: for He is not a man, that He should repent.” The explanation is very simple. When speaking of Himself, God frequently accommodates His language to our limited capacities. He describes Himself as clothed with bodily members, as eyes, ears, hands, etc. He speaks of Himself as “waking” (Psa 78:65), as “rising up early” (Jer 7:13); yet He neither slumbers nor sleeps. When He institutes a change in His dealings with men, He describes His course of conduct as “repenting.” Yes, God is immutable in His counsel. “The gifts and calling of God are without repentance” (Rom 11:29). It must be so, for “He is in one mind, and who can turn from Him? and what His soul desireth, even that He doeth” (Job 23:13).
