Philippians 4:6-8

"Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all He has done. If you do this, you will experience God's peace, which is far more wonderful than the human mind can understand. His peace will guard your hearts and minds as you live in Christ Jesus. And now, dear brothers and sisters, let me say one more thing as I close this letter. Fix your thoughts on what is true and honorable and right. Think about things that are pure and lovely and admirable. Think about things that are excellent and worthy of praise."
