The shelter, or secret place, of the Most High is open to “whoever believes.” God has already done His part. John 3:16 says, “For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life.”
God is light, and in Him is no darkness at all (1 John 1:5). There is no shadow of turning with Him (James 1:17). The shadow referred to here is the force field of God’s presence. Anyone who comes within shadow distance of God is covered by His power. The force field of the Almighty is unmatched.
He is the Alpha and Omega, the beginning and the end, and there is no power that is any match for the might, glory, and majesty of the Creator of all.
