Faith vs. Works is truly a very polarizing subject. I have written a few articles about it. Maybe you can start by reading the one HERE for starters if you're interested in my take on what James says. And as with Philippians, and working out your salvation with fear and trembling, I do not believe Paul is talking about eternal salvation here. If he was, then he would be contradicting himself. I would recommend that you read this article about Philippians 2:12. The term salvation does not always refer to eternal salvation. It's kind of like 1 Timothy 2:15 where Paul wrote that women will be saved through childbearing, IF they continue in faith, love and holiness with propriety. Obviously, Paul is not talking about women's eternal salvation here, otherwise it could lead to some pretty dodgy doctrines! Thanks for the comment :]
