Philippians 4:4-7

4 Rejoice in the Lord always; again I will say, Rejoice.
5 Let your gentleness be known to everyone. The Lord is near.
6 Do not worry about anything, 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 your minds in Christ Jesus.
