There is a distinct break in the train of thought at this point. The theological exposition, centering around the problem as to how sinful man can be put right with God, is over.

But there is more to be said, because when man is made right with his Maker, he needs to know what difference this makes in his relations with his fellowmen. He needs to know what is expected of him and how to apply his new resources to all the situations confronting him.

This last main section of the letter is designed to meet these needs (cp.12) Eph 4:1). The first part (Rom 1-11) is information designed for belief, while the last part (Rom 12-16) is exhortation designed for action. The first part stresses right relations with God, and the last part stresses right relations with other people — in short, and simply put, loving the Lord your God, and loving your brother, and neighbor, as yourself (Luke 10:27; Matt 22:37-40; Mark 12:30,31).

Romans chapters 1-11 describes, in the broadest terms, our fellowship with the Father and the Son. Then the final chapters of Romans describe, in the same way, our fellowship with one another.
