Immutability: Meaning

The teaching of Scripture on immutability sounds rather dull to many ears but is actually one of the foundations of a believer’s faith. After a study on immutability, Christianity shines forth with a glory that was not seen previously. This is a beautiful attribute of God that is denounced and denied by many in our day, but in so doing they are denying Christianity. This is a necessary teaching of the Christian faith if the Christian faith is going to remain the same in terms of its foundational doctrines. If the foundational doctrines change, then Christianity has changed from Christianity to something else.

The immutability of God is the attribute of God that signifies His perfection of essence and will. He is perfect in His essence and will and so He does not change and cannot change. For God to change would imply one of a few different things. He would either have to change Himself or another would have to change Him. For another to change Him would require a greater wisdom and a greater power. That simply cannot be as that would mean that God would be a god and not the true God. For God to change Himself would mean that He would either change for the better or for the worse. If for the better, then He is not perfect. If for the worse, then He is not perfect. Therefore, we can know that the perfect God will never change since He can get neither better nor worse.

More importantly, the Scriptures teach this:

1 Samuel 15:29 – “Also the Glory of Israel will not lie or change His mind; for He is not a man that He should change His mind.”

Malachi 3:6 – “For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed.”

Numbers 23:19 – “God is not a man, that He should lie, Nor a son of man, that He should repent; Has He said, and will He not do it? Or has He spoken, and will He not make it good?”

Hebrews 6:18 – “so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us.”

Hebrews 13:8 – “Jesus Christ is the same yesterday and today and forever.”

James 1:17 – “Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow.”

Deuteronomy 32:4 – “The Rock! His work is perfect, For all His ways are just; A God of faithfulness and without injustice, Righteous and upright is He.”

In the last text we see that God is called “The Rock.” Then it tells us that His work is perfect. Both of these show God to be immutable. God is the Rock that cannot be moved. He is the Rock that does not change. But the fact that He is perfect shows clearly that He cannot change. As we have seen from above, if He is perfect then He cannot change for the better or for the worse. Any change at all shows that He is less than perfect. As we can see from the texts of Scripture above, the fact that God is immutable means that He cannot lie. The Word of God cannot fail because the God who spoke them and speaks them cannot change and cannot fail. As a God that cannot lie, He is perfectly faithful to be who He is and to do all that He says.

Because God is immutable we don’t have to worry that the Gospel will change before the day or week is out. The Gospel is founded on His promises which means the Gospel is only as good as the words of God are. God’s words are only as good as He is immutable. But since He is immutable and cannot change, but instead exists in perfect beauty and love, the Gospel will never change. Christianity cannot be anything but the manifestation of the glory of God which is full of truth and grace (John 1:14). The truth of Christianity rests upon the truth of God and of the God who does not change. This is why the Gospel is the eternal Gospel and it will always be the one and only Gospel. God never changes His Word and His Son never changes. Therefore, we are not consumed.
