Written from prison, Paul provides a four-step prescription for anxiety: don't be anxious, pray about everything, request with thanksgiving, and receive God's peace. The Greek word "merimnaō" means "to be pulled in different directions" - exactly how anxiety feels.
Paul contrasts this scattered state with focused prayer that results in divine peace that "guards" (Greek: phroureo, a military term for standing watch) our hearts and minds (BibleHub Commentaries).
