I guess you can't have a proper debate on the subject without must first nail down the definitions of the words "grace" "faith" and "works."
Regardless of the whole faith, grace, and works business, I suspect that anyone who dies knowing God and truly loving Him will be saved. (When you realize who He is and what He has done/suffered for you, then it is hard not to love Him back). That seems to be the key. I would propose to you that it is impossible to be saved without loving God, but you have to know who He is before you can truly begin to do that. You can't love what you don't know.
Yes, you are quite correct. It is difficult to discuss the Biblical terms, ‘grace,’ ‘faith’ and ‘belief’ with someone not familiar with the Biblical understanding of those words.
The poster I was responding to in that post seemed not to be familiar with those Biblical concepts so I limited my discussion to the difference between belief (even the demons believe) and faith.
