Philippians 4:4-7

4 Rejoice in the Lord always. Again I will say, rejoice!

5 Let your gentleness be known to all men. The Lord is at hand.

6 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.

(NKJV)
