Philippians 4:6-7
King James Version
“Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.”
New International Version
“Do not be anxious about anything, but in every situation, 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.”
Commentary
This is arguably the Bible's most direct and practical teaching on anxiety. Paul writes not from a place of comfort but from a Roman prison cell — which makes his instruction all the more remarkable. The command is total ("anything"), the method is specific (prayer + petition + thanksgiving), and the promise is stunning: peace that exceeds human comprehension will act as a military guard ("keep") over your inner life. The word translated "careful" (KJV) or "anxious" (NIV) is the Greek merimnaō, which means to be divided — pulled in multiple directions. Paul's solution is to redirect that divided attention to God.
