Philippians 2:14-16

Do all things without complaining and disputing, that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world, holding fast the word of life, so that I may rejoice in the day of Christ that I have not run in vain or labored in vain.

Philippians 4:6-7

Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God;
and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
