So perhasps you could explain to your peers Rom 4:1-5 does not teach God justifies unbelievers.Paul was the apostle to the Gentiles, not some anonymous Internet poster calling himself "SavedByTheLord".
That is why I read and study Paul's letters so much (of course, not only Paul's letters).
Watch out for deception from "SavedByTheLord's" writings.
See how that works?
