Peace when I sleep, please.

"In peace I will both lie down and sleep; for you alone, O LORD, make me dwell in safety." In psalms we can read, meditate on(consider, and ponder over and over again), pray about it, and believe in the peace and safety that God alone can and will give you, enabling you to actually sleep...have you read it? Meditated on it? prayed about it? Believe His words? Then rest easy, sleep...
