In peace I will both lie down and sleep; for you alone, O Lord, make me dwell in safety. ~ Psalm 4:8 (ESV)
After having gone through a few nights with trouble sleeping, I can attest to the value of peaceful slumber. The Psalmist rested in spite of turmoil and trouble on all sides because the Lord granted him safety. How often we retreat from our haven of rest because we seek safety in our own efforts to predict or control future events. We lay awake at night, turning over various scenarios in our minds, forgetting that only the Lord can give us surety for tomorrow.
