Paul wrote into a real dilemma the Philippians faced before his letter arrived. God’s peace fills the letter itself as well as its content. Ephesians 2 shows that this peace outlasts every circumstance, because it is eternal.
Government and media quietly dictate morality today, much as the Roman moral code shaped Paul’s readers. The qualities Paul lists in 4:8, whatever is true, honorable, and the rest, are Christ’s own qualities, transcendent and heavenly. God’s promised peace makes pursuing them possible.
The story in 2 Kings 6 of Elisha surrounded by an enemy army has its humor as well as its drama. Elisha’s calm already shows the peace of God that passes understanding, the peace Philippians 4:7 names. Paul tells the Philippians that the same peace is theirs in their own predicament.
Earthly peace fades and heavenly peace lasts, and 4:6-7 promises believers the heavenly kind. Forbearance with others belongs to that promised peace. Anxiety can be sinful, and praying for others with thanksgiving answers it.
