Yet James is talking about an empty profession of faith/dead faith that remains alone - "barren of works." So faith in "faith only" here is not genuine faith, but a bare profession of faith. This is what works-salvationists cannot seem to grasp. *Not to be confused with salvation through faith (rightly understood) IN CHRIST ALONE (Ephesians 2:8,9).
In James 2:14, we read of one who says/claims he has faith but has no works (to validate his claim). That is not genuine faith, but a bare profession of faith. So when James asks, "Can that faith save him?" he is saying nothing against genuine faith, but only against an empty profession of faith/dead faith. *So James does not teach that we are saved "by" works. His concern is to show the reality of the faith professed by the individual (James 2:18) and demonstrate that the faith claimed (James 2:14) by the individual is genuine. Simple!
Yet grace is God's part and faith is our part. Ephesians 2:8 (AMPC) - For it is by free grace (God’s unmerited favor) that you are saved delivered from judgment and made partakers of Christ’s salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God.
To be specific, we are saved through faith IN CHRIST ALONE (by trusting in Christ alone for salvation and not in works). Saved through faith, not works. Faith (rightly understood) IN CHRIST ALONE.
We are either saved through faith in Christ alone or through faith in Christ + works. I believe that we are saved through faith in Christ alone. Authentic faith in Christ is not a dead faith that remains alone - "barren of works" because it's a living faith, but nonetheless, we are saved through faith, not works.
