As we continue to live out the dictum, "as iron sharpens iron, so does one man sharpen another," on the Antinomian question, here is a gem from Luther's Twenty-First Argument from his Second Disputation Against the Antinomians in Solus Decalogus Est Aeternus: Martin Luther's Complete Antinomian Theses and Disputations.
The law is already mitigated greatly by the justification which we have because of Christ; and it thus ought not to terrify the justified. Yet meanwhile Satan himself comes along and makes it often overly harsh among the justified. This is why it happens that those are often terrified who ought not to be, by the fault of the devil.
This is how we are to preach the law according to Luther: " . . . so as to admonish to good. . . . by way of exhortation . . . ." The law is not just for the lawless, to terrify. It is to be preached to the pious so as to admonish to good.
