Many of us, at one time or another, have either wished for a guardian angel, or have called someone that because they’ve somehow helped save us from disaster. The psalmist who wrote Psalm 57 could certainly have used one, being threatened by people who were pursuing him to kill him. But even in the face of that threat, the psalmist speaks of God’s love and faithfulness as if they were the very emissaries of God, sent for the psalmist’s protection. And because of this, the psalmist sings joyfully, with a song loud enough to awaken the dawn.
