As Daredevel7 said about compassion, "Evidence that it can come from within?"
Yep, mental problems can come from within. That's why I don't trust philosophical models that rely purely on solipsism (yours doesn't, that was just a random comment).
I don't know. Did the person who continues to sin even profess that he was a born-again Christian to begin with?
There are a great many who have and do. I see nothing contradictory with someone believing that Jesus is their savior and all of that (yes, oversimplifying), and "continuing to sin". That includes ignoring the fact that naturally all believers who don't convert and then immediately die "continue to sin". You can claim that someone who "truly believes would not do so" and thus anyone who does continue to sin never was a "true believer", but then that's merely because that's how you've defined "true believer" to be, rather than actually having anything to do with a result of belief.
Legalism is the belief that salvation is acquired by following a set of rules; that is, salvation by works. Salvation by grace is not the same as legalism.
No, no. I mean, that might be one form of legalism. I'm using it in the broader moral sense of what is right and wrong. Salvation doesn't come into play since I think that's make-believe.
But seriously, I'm using it more in the sense of extrinsic vs intrinsic decision theory. Legalism (as I'm using it) is the system whereby you are handed a set of rules (stone tablets, if you will) and told that those are defined as "right and wrong". The inherent problem with legalism of this sort is easily seen in the following situation:
1) God is mysterious to humans, and we cannot predict his actions.
2) God is superior to humans, which is why we must obey his commands.
3) God hands you a stone tablet, containing the 11th commandment: Thou Shalt Rape The Virgins.
If situations one and two are acceptable to you, but situation three is not, then you are not truly following the edicts of an external entity; you are applying an intrinsic model of right and wrong, and when the source for your (what I'm calling legalistic) model conflicts with your intrinsic estimation of what the external source says should be true, you contradict either situations one or two.
If the third situation is acceptable to you... then in terms applicable to you, "may God have mercy on your soul", lol.
My moral framework is provided by an all-knowing, all-loving, eternal, unchanging, omniscient God.
I'm not going to say what the moral framework is for others. If you or anyone wants to say what your or their moral framework is, that's fine.
If the above situation seems unfathomable or impossible to you, then you've either modified that moral framework so that it extends beyond that (in which case it is now subject to your personal control), or you're trying to limit your supposedly omniscient and all-powerful (you left that one out, but I'll assume it was meant to be included) God to merely human feelings, thoughts and emotions.
