Scripture
Peace
Prayer instead of worry: Philippians 4:6–7 and John 14:27.
Philippians 4:6
Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
Philippians 4:7
And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
John 14:27
Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
