Since God exists eternally He is unchanging. He is not growing, progressing, evolving, or in any way moving from a state of imperfection to a state of perfection. This is the teaching of the Scriptures. Indeed, the very fact that God is unchangingly faithful to His promises to Israel is based upon the understanding that Yahweh himself does not change with time: “For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed” (Malachi 3:6).
