I never said a person wasn't justified upon hearing with faith--faith is accounted as righteousness, so there is a basis for God justifying--but, thereafter, the believer is to not merely hold faith, but also walk in faith, and that walking in faith, as seen in Ro 14:5,23, and Ja 2 (just two examples--there are more), determine ongoing justification.
The thing is that I recognize NOT ONLY justification by the righteousness of faith, but also "ongoing justification" (Ro 14:23; Ja 2), and "final justification" (eg, Ro 2:6-16) by the righteousness of faith completed by also walking in faith. I'm endeavoring to believe it ALL, not just a sliver of it.
