Philippians 4:7 note 1 (RcV)

Philippians 4:7
And the ¹peace of God, which surpasses every man’s understanding, will guard your hearts and your thoughts in Christ Jesus.

7¹ The result of practicing fellowship with God in prayer is that we enjoy the peace of God. The peace of God is actually God as peace (v. 9) infused into us through our fellowship with Him by prayer, as the counterpoise to troubles and the antidote to anxiety (John 16:33).
