Be anxious for nothing but in prayer and supplication with thanksgiving let your requests be made known to God and the peace of God, which surpasses all comprehension, shall guard your heart and your mind in Christ Jesus.
Finally, my friends, whatever is true, whatever is honorable, whatever is right, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind dwell on these things.

-Philippians 4:6-8
