John 14:27 (KJV) Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
The peace left and given to us is the Lord’s peace itself. There is no greater peace than that. There’s not a moment when the Lord’s ever worried or scared; it’s understandable why we too are not troubled or afraid.
