From today's devotional
God's protection of his people is limitless and can take many forms. David characterized God's care with five military symbols. God is like (1) a rock that can't be moved by any who would harm us, (2) a fortress or place of safety where the enemy can't follow, (3) a shield that comes between us and harm, (4) a horn of salvation-a symbol of might and power, and (5) a stronghold high above our enemies. If you need protection, look to God.
