Philippians 4:6; Philippians 4:8-9

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