God is Immutable (Never Changes)

Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning. (James 1:17)

For I am the LORD, I change not; therefore ye sons of Jacob are not consumed. (Malachi 3:6)

Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath: That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us: (Hebrews 6:17-18)

He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he. (Deuteronomy 32:4)
