Maybe the words are getting in the way here.
I’m quite familiar with James; it would be my guess that I’ve read James more than I’ve read any other book in the Bible with the possible exception of Romans. I think James speaks primarily about faith and works, what it means to have faith and what relationship faith has to works. As we know, faith without works is dead (btw, I watched part of an old Billy Graham special in black and white last night on the tube…quoting James he was emphatic that a faith consisting of mere intellectual assent was no faith…a faith no better than that held by the demons…). Still, James speaks to faith and works more than to grace.
In contrast, by “grace alone” we believe that nothing we can do, no works, no faith, no good deeds, nothing can save ourselves. We are saved only by the grace of God. Absent the grace of God, we could have the faith of angels and the utmost in good works and neither would not save us.
