Guarded Inside
"Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus."
— Philippians 4:6-7
Paul wrote this from a Roman prison, chained to a guard. He told anxious people to pray with thanks. Then God's peace would guard their hearts like soldiers at a gate. Paul was not free, yet he found calm inside chains. Peace here means your heart can rest even when the problem stays.
