Obviously, or so it would seem to the uninitiated, there is no place for works in justification in Calvinism.
Justification is completely apart from works.
Recently I re-read parts of a book, Wrongly Dividing the Word of Truth , by the late Dr. John Gerstner, a very staunch Calvinist. I saw something I had not seen in my previous reading of that book. Good works, while a necessary complement of true faith, are never the meritorious grounds of justification, of acceptance before God. From the essential truth that no sinner in himself can merit salvation, the antinomian draws the erroneous conclusion that good works need not even accompany faith in the saint. The question is not whether good works are necessary to salvation, but in what way are they necessary.
