All very logical and as such rather beside the point.
I suppose there are believers out there insisting on the literal truth of The Book of Revelation just as there are atheists using it as a stick to beat Christianity. Mirrors of each other. That's the thing about Clobber Verses: The clobbering can work both ways.
In the literal believer camp I doubt that they give any serious thought to how appalling it would be to live forever.

I'm glad you write this sort of thing, and that I from time to time tell myself, "Paul, you should step outside your bubble and read that." With you I know it will be engagingly written.
