I honestly don't care if you call it part of salvation or not. I know if Peter didn't do it, he was OUT. (In my thinking, that's kind of a salvation-ish thing, but how we catagorize it doesn't really matter)Seeking, learning, Growing Submitting is a part of sanctification process.
Not the salvation process.
I assume you think you can earn your salvation also?? What do you have that you can offer God that would be so great it would prevent him from having to die for your sin?
Also, you'd be wrong in your assumption.
