Philippians 4:4-9 New King James Version (NKJV)
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.
8 Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things. 9 The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you.
