Philippians 4:4-7 (New King James Version)

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.
