Does not the gospel establish the Law?

For we hold that one is justified by faith apart from works of the law...Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law. Romans 3:28,31
Is the distinction between Law and Gospel as sharp as some presume or teach?

How about the conclusion to a paper. Should the conclusion be distinct (or contrary) to the body of the paper, or should it strengthen and "fulfill" it?
