philippians 4:4-7
4 Rejoice in the Lord always; again I will say, rejoice! 5 Let your gentle spirit be known to all men. The Lord is near. 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 comprehension, will guard your hearts and your minds in Christ Jesus.
