[Melian]

The Letters of the Apostles are rife with passages indicating that one must live Christ’s words, not just talk about them.

If mere belief was enough for salvation, why would Paul write to various groups of converts cautioning them that they were on the wrong track? Weren’t they “saved” by virtue of being Christians? No. He wrote because they were in jeopardy of losing their salvation by improper beliefs, misunderstandings, and impure acts.

In other words, their actions were not in keeping with belonging to Christ. Paul seemed to think that was pretty serious!

True. However, those same passages don't say anything along the lines of living Christ's words save you. What they say is that a saved person is required to live out Christ's words. There is a difference. One is a belief that salvation comes from your works and the other is that your good works comes about because of your salvation.

Please post the verses which say that people were "in jeapardy of losing their salvation by improper beliefs, misunderstandings and impure acts."
