Despite being chained between two Roman soldiers and facing the possibility of execution the next day, Peter was asleep. (He probably was the only Christian who slept that night.) In fact, it seems that Peter was in such a deep slumber that it took a whack from an angel to wake him up: "Suddenly, there was a bright light in the cell, and an angel of the Lord stood before Peter. The angel struck him on the side to awaken him and said, 'Quick! Get up!' And the chains fell off his wrists" (verse 7).
What gave Peter such confidence and peace? He knew that people were praying for him. In the Psalms David said, "In peace I will lie down and sleep, for you alone, O LORD, will keep me safe" (4:8). And David's son Solomon wrote, "God gives rest to his loved ones" (127:2).
I know that people are praying for me when we hold our Harvest Crusades. I simply feel prayed for. It is comforting to know that others are praying for you.
Most of us know what it's like to wake up in the middle of the night with things on our minds. When this happens, I will pray. I will say, "Lord, it's 3:00 a.m. There's nothing I can do about these things. I'm going back to sleep, so you worry about this." Philippians 4:6–7 tells us, "Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God's peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus" (verse 7).
Do you sleep in peace? It is a great thing to go to sleep with a clean conscience.
