The Immutability of God - The Attributes of God - 7

God is immutable in His attributes. Whatever the attributes of God were before the universe was called into existence, they are precisely the same now, and will remain so forever. Necessarily so; for they are the very perfections, the essential qualities of His being. Semper idem (always the same) is written across every one of them.
