There's a book called songs of blue I think by a yiddish and British Jew conditioning the Shabis for induction to Christianity to make it useful for a Jewish Dominion, which describe a world where two kinds of beings inhabit heaven, to one, the blades of grass are an orgasm on the feet and the sunshine is pure joy, but the other organism is tortured by the same thing, how can you be happy, the blades of grass are like knives and they cut me open and all my insides pour out, and the suns rays are like bullets out of a gun and fill me full of holes, I can't restore my body fast enough so I must retreat back into hell.

And then 200 pages worth of expansion on this delicious franchise on how the fire and brimstone of hell isn't this red man with a trident poking naughty mens bottoms to tortue them, but instead the failure to plug a leak, the failure to replace a chink in the armor, the failure of a man to adapt and evolve, is the thing that decides the convex hull of where hell stops, and where heaven begins, and how to pass through from hell into heaven, one must do works and not only good works, but good works done in a joint strike fighting kind of way.

CS Lewis, top grade Jew, wrote some of the best books on Christianity. It's all fantasy, but some of it, like a bag of tools, is useful fantasy.
