Then WHY "ALL" the confusion? Over a little word like "ALL"
You are saying it doesn't mean ALL, but "some"...By definition alone, this is confusion. You take scripture that speaks plain English, translated from PLAIN GREEK, and make it something it isn't. Not some dump outside of Jerusalem, translated in English to mean a fiery lake inferno, where billions of people will be slaughtered by the Holiest of Holies, according to the doctrines of some in this place called "hell".
They don't even know when the book of Revelation was even written, and can at best, guess. But guess only when it suits your brand of doctrines, of course. Don't count those Jews who died in 70AD, and had their bodies burned outside the gates, in the actual Gehenna. Of course it couldn't mean that now, could it? That wouldn't be a judgment, no different than what happened at Sodom, would it? Kinda like the one Jesus TOLD them was going to happen?
Oh well, maybe not. Guess with ALL this confusion, we shall just have to sift out the wheat from the tares....the Truth from the Lies.
Keep searching, it is there
