"For a moral being to change it would be necessary that the change be in one of three directions. He must go from better to worse or from worse to better; or, granted that the moral quality remain stable, he must change within himself, as from immature to mature or from one order of being to another. It should be clear that God can move in none of these directions. His perfections forever rule out any such possibility." -A.W. Tozer on the immutability of God
