But what you ask of earth? Earth, I think, will not be found by anyone to be in the end a very distinct place. I think earth, if chosen instead of Heaven, will turn out to have been, all along, only a region in Hell: and earth, if put second to Heaven, to have been from the beginning a part of Heaven itself.
“‘That is what mortals misunderstand. They say of some temporal suffering, ‘No future bliss can make up for it,’ not knowing that Heaven, once attained, will work backwards and turn even that agony into a glory. And of some sinful pleasure they say ‘Let me have but this and I’ll take the consequences’: little dreaming how damnation will spread back and back into their past and contaminate the pleasure of sin. Both processes begin even before death. The good man’s past begins to change so that his forgiven sins and remembered sorrows take on the quality of Heaven: the bad man’s past already conforms to his badness and is filled only with dreariness. And that is why, at the end of all things, when the sun rises here and the twilight turns to blackness down there, the Blessed will say ‘We have never lived anywhere except Heaven,’ and the Lost, ‘We were always in Hell.’ And both will speak truly.’
‘Is that not very hard Sir?’
‘I mean, that is the real sense of what they will say. In the actual language of the Lost, the words will be different, no doubt. One will say he has always served his country right or wrong; and another that he has sacrificed everything to his Art; and some that they’ve never been taken in, and some that, thank God, they’ve always looked after Number One, and nearly all, that, at least they’ve been true to themselves.’
‘And the Saved?’
‘Ah, the Saved… what happens to them is best described as the opposite of a mirage. What seemed, when they entered it, to be the vale of misery turns out, when they look back, to have been a well; and where present experience saw only salt deserts, memory truthfully records that the pools were full of water.’” -Excerpt from C.S. Lewis’- The Great Divorce
