We have already seen the foundation of Paul’s argument in the book of Romans (the person and work of Jesus the Christ), and the goal(s) of his argument (gospel unity and the obedience of faith, particularly as it relates to proclaiming the good news about Jesus), but what is the main point of Paul’s argument? What is it he is arguing, that rests on Jesus, that results in obedient proclamation of the gospel to all? Why did Paul write? And what benefit is it to Christians today? In a word, it is the gospel itself.
