Bible says that God never changes. This concept is expressed in several verses across both the Old and New Testaments. Here are a few key examples:

Old Testament

For I am the Lord, I do not change; Therefore you are not consumed, O sons of Jacob. — Malachi 3:6, NKJV (Note: This is the most direct verse affirming God’s immutability. He does not change.)

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? — Numbers 23:19, NKJV (Note: This shows that unlike humans, God does not lie or change His mind.)

New Testament

Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning. — James 1:17, NKJV (This means that God does not change like shifting shadows. His nature is constant.)

Theological Summary

In Christian theology, this concept is called “immutability”. God’s nature, character, and will do not change over time. He is eternal, perfect, and consistent.
