No real problem. Some of them are interesting. It's just evangelical Christian theology. Nothing I'm not familiar with.
God is spelt with a capital G.
As a
proper noun (e.g. the Christian deity in specific) your right, but as a
common noun (i.e. a deity of some religion in general) "god" with a lower-case "g" is alright. And since SWE doesn't believe in any specific deity, "god" works fine.
That said, his signature does sound like a threat.
I think that's just evangelical Christianity--or I suppose, Christianity as a whole.
It's a terrifying concept if you think about it.
The concept is that there's this "straight and narrow" path, yet most people don't take that path and end up suffering for eternity. Sure, if you get your ticket you're okay, but many of your friends and family are stuck with maximum possible torment, despair, et al. That's why so many Christians who really think about it are annihilationists (which isn't too much better) or universalists. Or, like me, left it altogether.
It's silly to suggest RFayette's trolling, or is doing it out of self-righteousness. I'll give him the benefit of the doubt. I mean, if you believe in hell, and that it's a really bad place, I don't understand how you could
avoid going crazy evangelizing everywhere, and lose sleep wondering if your friends and family--or just random people--are safe. It would be
brutal.
