Philippians 4:6-8

6Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.

7And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. 8Finally, 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.
