Discover how the church brings together what the world has separated, transcending the boundaries that divide--national partitions, racial barriers, class distinctions, and political partisanship. Paul writes these letters from prison, as "an ambassador in chains" for preaching the gospel, demonstrating how struggle and resistance can unite believers and enhance their witness to Christ. This unity of the church--forming one body and one Spirit, joined in one hope, one Lord, one faith, and one baptism--is God's gift as well as a goal to be achieved through the transforming power of the gospel.
