The Apostle Paul is concerned to see the transforming power of the gospel made obvious in the lives of the Philippians. At the heart of the letter is the command to “conduct your life in a manner worthy of the gospel of Christ” (v. 27). With the sufferings of Christ in view, the Lord’s people are to stand firm in one spirit as one soul. Not only has God graciously given the gift of salvation, but he has also granted on behalf of Christ that his people suffer for Him. Whether anxieties within or threats without, they can know for certain that everything is brought about by God for the good of His people: their sufferings are a sign of their salvation.
