The doctrine of immutability means that God does not change. He is the same in His nature, character, and purposes at all times. The word “immutable” simply means unchanging. The Bible clearly teaches this. Malachi 3:6 says, “For I am the LORD, I change not.” James 1:17 says there is no “shadow of turning” with God. Hebrews 6:17–18 also shows that God’s counsel is unchangeable and that it is impossible for Him to lie. This means God cannot become better or worse—He is already perfect and complete in all His ways.
However, some parts of the Bible seem to show God changing His mind. For example, in Exodus 32:10–14, God said He would destroy Israel because of their sin. But after Moses prayed, God “relented” and did not carry out the judgment. Also, in Jonah 3:10, God planned to destroy Nineveh, but when the people repented, He did not do it. Another example is found in 2 Kings 20:1–6, where King Hezekiah was told he would die, but after he prayed, God added fifteen years to his life. These examples can make it look like God changes.

To understand this, we must know that immutability does not mean God is inactive. God is living and relates with people. People change, and because of that, God’s actions toward them may also change. But this does not mean His nature has changed.

In Exodus 32, Moses prayed and asked God to remember His covenant with Abraham (Genesis 12:1–3). God showed mercy, which is part of His nature. So, God did not change—He acted according to who He has always been. In Jonah 3:10, the people repented, and God forgave them. This also agrees with God’s character, because He is merciful and willing to forgive (Psalm 86:5). In the case of Hezekiah, God responded to sincere prayer, showing that He listens and responds to His people.

The Bible explains this clearly in Jeremiah 18:7–10. God says that if He speaks judgment and people repent, He will not bring the judgment. But if He promises blessing and people turn to evil, He may remove the blessing. This shows that God’s actions depend on how people respond, but His character stays the same.

We also see that God’s plans do not change. Numbers 23:19 says God is not a man that He should lie or repent. 1 Samuel 15:29 says the Strength of Israel will not lie or change His mind like a man. Psalm 102:27 says, “Thou art the same.” These verses confirm that God remains constant.

So how do we reconcile this? The answer is simple:
God does not change in who He is, but He may change in how He deals with people because they change.
God is always holy, just, and merciful. When people sin, He judges. When they repent, He forgives. His response may look different, but it is always based on the same unchanging nature.

In conclusion, there is no contradiction. The Bible shows both that God does not change and that He responds to people. These do not oppose each other but work together. God is always consistent in His character and faithful to His Word. This gives believers confidence, knowing that God is reliable, trustworthy, and will always remain the same.
