Sleep in heavenly peace. Is that even possible? It really is. I know, I had to learn to rest in His love and receive His peace.
In peace will I lie down and sleep for you alone O Lord, make to dwell in safety. Psalm 4:8
When you lie down you will not be afraid, when you lie down your sleep will be sweet. Proverbs 3:24
He will keep you in perfect peace if your mind is stayed ( focused ) on Him. Isaiah 26:3
