We all agree that someone must have faith in Christ for salvation. Calvinists argue that faith comes as a result of an effectual work in the heart of the man irresistibly producing saving faith in Christ. Non-Cals argue that faith comes as a result of hearing God's words, but not effectually or "irresistibly" so. So, we both affirm faith results from God's work, but one is an effectual work and the other is not. Now, here is the question: Whether faith is produced effectually or not, is it considered a "work?" If not, why not? Isn't it something man still must do, even if its as a result of an effectual working? If so, then do we all believe that men are saved by grace through a work? Or could it be that Paul was showing the difference in the works of the law and faith in the one who fulfilled the law for us?
