⁴ Rejoice in the Lord always. I will say it again: Rejoice! ⁵ Let your gentleness be evident to all. The Lord is near. ⁶ Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. ⁷ And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.

 ⁸ Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. ⁹ Whatever you have learned or received or heard from me, or seen in me—put it into practice. And the God of peace will be with you. 

Philippians 4:4-9
