The image is of complete enclosure — God behind (the past) and before (the future), with His hand resting on top. There is no direction from which God is absent; we are completely held.
Memory phrase: God surrounds me on every side.
Talk about it: Have you ever been given a hug from behind that surprised you? How is God surrounding us like that?
Prayer: Lord, You are in front of me and behind me. Help me feel Your hand on me today — especially when I am afraid.
