Okay, I'm tackling this one now. Sort of kept it on the back burner (ha ha) for a while, but I can't anymore. So I'm reading this article by Steve Scianni. I also bought a book by Greg Boyd on this topic. I need to find good works by the other side.
This may take a while to sort out. But this morning I was struck by how few Scripture verses (at least according to my Thompson Chain Reference NIV) there were to support the everlasting torment theory, and they seemed sort of flimsy, at least more flimsy than should be required to develop a whole doctrine out of.
Sola Scriptura, and let the chips fall where they may!
