four through seven
do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. and the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
ten through thirteen
i rejoice greatly in the Lord that at last you have renewed your concern for me. indeed, you have been concerned, but you had no opportunity to show it. i am not saying this because i am in need, for i have learned to be content whatever the circumstances. i know what it is to be in need, and i know what it is to have plenty, i have learned the secret of being content in any and ever situation, whether well fed or hungry, whether living in plenty or in want. i can do everything through him who gives me strength.
proverbs four twenty three
above all else, guard your heart, for it is the wellspring of life.
