C. S. Lewis' The Great Divorce is a fascinating story about the "Divorce" of Heaven and Hell. In many ways the book is hard to summarize. Basically, a man (Lewis?) is given a glimpse into the afterlife and finds the words of writer John Milton to be true: "The choice of every lost soul can be expressed in the words 'Better to reign in Hell than to serve in Heaven.'"
The story opens with a picture of a dark city (Hell/Purgatory) where people wait in line to board a bus to take them to a world full of light (Heaven). Once they arrive, each of the people finds themselves to be less than a person. They are ghostly figures who cannot even bend the grass of Heaven when they walk. While there, each is approached by a heavenly being (Deceased Christian) who seeks to take them on a journey to the heavenly mountain. Along the journey the ghostly person will be transformed and be able to remain in Heaven. The man wanders around the heavenly place and overhears a number of conversations between the ghostly figures and the heavenly beings. Almost every conversation ends the same way: The ghostly figure, in plain sight of heaven, chooses to return to Hell.
I would highly recommend The Great Divorce to anyone, though with two cautions. First, one should carefully read the preface before starting. There, Lewis makes it clear that the book is not fact, nor is it theology, it is fantasy and should be read as such. Second, don't miss the moral. Sadly, while reading the book, I think that I did exactly the opposite of what Lewis intended for his readers and missed the moral completely. In the ghostly people who were choosing Hell over heaven, I kept seeing people I knew, instead of seeing myself.
Here are a couple of quotes:
If we insist on keeping Hell (or even Earth) we shall not see Heaven; if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell. I believe, to be sure, that any man who reaches Heaven will find that what he has abandoned (even the plucking out of his right eye) has not been lost. . . (Preface, IX)
'[Hell] is closer to such as you than ye think. There have been men before who got so interested in proving the existence of God that they came to care nothing for God himself. . . as if the good Lord had nothing to do but exist! There have been some who were so occupied in spreading Christianity that they never gave a thought to Christ. Man! Ye see it in smaller matters. Did you even know a lover of books that with all his first editions and signed copies had lost the power to read them? Or an organiser of charities that had lost all love for the poor? It is the subtlest of all the snares.' (p. 73-74)
