Peter was therefore kept in prison, but constant prayer was offered to God for him by the church. And when Herod was about to bring him out, that night Peter was sleeping, bound with two chains between two soldiers; and the guards before the door were keeping the prison.
Acts 12:5-6

Peter was in jail for his faith in Christ. Even while in a jail cell, Peter was chained to two guards. How’s that for security!? There was no human possibility of escape. And time was running out because the next day Herod was going to “bring him out,” not for release, but for trial and probable execution. I guess the troubles I fret over are nothing compared to Peter’s situation.

Yet Peter was asleep. Though Peter had legitimate reason for anxiety, he had peace enough to sleep. (Not unlike His Savior when Jesus was asleep on the boat in the midst of a life-threatening storm! Mark 4:37-38) It is not God’s will that His children be anxious—no matter how understandable it may be. True, God uses our anxiety to draw us near to Him. His will is that as we draw near to Him, we might experience His perfect peace.

When anxious, prayerfully meditate on these three passages:

John 14:1 & 27 "Let not your heart be troubled; you believe in God, believe also in Me... 27 Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid.

Isaiah 26:3 You will keep him in perfect peace, Whose mind is stayed on You, Because he trusts in You.

Philippians 4:6-7 Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; 7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
