The one to start with.
In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus. Philippians 4:6-7
In the multitude of my thoughts within me, your comforts delight my soul. Psalm 94:19
Lord, my mind won’t stop. I’m bringing every anxious thought to You. I can’t fix them all, but You can hold them. Give me the peace that doesn’t make sense, and let it guard my heart and my thoughts. Be the comfort in the middle of my worry. In Jesus’ name, amen.
