[Peace] is the very essence of His nature, one of His attributes. God is at all times at perfect peace, without any discord within Himself. He is never under stress, worried, anxious, fearful, unsure, or threatened. He is always perfectly calm, tranquil, and content. There are no surprises for His omniscience, no changes for His immutability, no threats to His sovereignty, no doubts to cloud His wisdom, no sin to stain His holiness. Even His wrath is clear, controlled, calm, and confident.
