All this talk of unity is not meant simply for the immediate body of believers; rather, it extends out to talk about all of our partnerships and how we are to have unity with them. For us at Crossway, that means the unity we have with our sister churches in the SBC, and our missionaries across the world. Paul sees this connected, not just to practical matters in Rome, but to the very purpose of God in the gospel. How are we to live in that purpose?
