Phil. 4:6-7

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.

If you were in service Sunday Pastor Bill talked about developing above your trouble, and not letting your heart be troubled. This verse makes doing those things very easy. When anxiety or trouble tries to enter your heart guard it with all diligence (Prov. 4:23) and simply trust God.
