D. Patrick Ramsey regularly writes the most direct and helpful summaries of a view I disagree with. While most discussions on the role of good works quickly devolve into confusion and endless circles and talking passed one another, Ramsey’s posts cut to the chase – which makes dialogue much more meaningful.
In a post over at Meet the Puritans, he explains that when he and others (like Mark Jones) argue against “Antinomianism,” what they are arguing against is the idea that our good works are only a fruit of our faith. The role of the law as a guide in the believer’s life is not the issue. Both sides agree on that. Rather, Ramsey argues “We don’t engage in good works merely because we live or are saved, we are to do them in order to live or to salvation.”
The “narrow way” is not Christ, but your good works (which they would say is Christ’s work in us).
Another common way the puritans articulated this same point was by covenant conditions. Sincere obedience is a consequent condition of justification and an antecedent condition of glorification… Good works, therefore, are more than fruit in that they are necessary for salvation as the way to eternal life and as an antecedent condition of glorification.
You will not merely have fruit when you are glorified, your fruit is a condition of whether or not you will be glorified. He says Tobias Crisp was wrong when he said that true Christians ought and will produce good works, but they are not required to and indeed they shouldn’t pursue holiness in order to avoid damnation and to possess heaven.
I don’t think it can be stated any clearer. Now go study Leviticus 18:5 and decide what you believe. Here are two posts that explain why I agree with Crisp and the “Antinomians”
