“And yet all loneliness, angers, hatreds, envies, and itchings that (Hell) contains, if rolled into one single experience and put into the scale against the least moment of the joy that is felt by the least in Heaven, would have no weight that could be registered at all. Bad cannot succeed even in being bad as truly as good is good.”
― C.S. Lewis, The Great Divorce

“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 to exist. There have been some who were so preoccupied with spreading Christianity that they never gave a thought to Christ.”

“Son,'he said,' ye cannot in your present state understand eternity...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 the 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...the Blessed will say "We have never lived anywhere except in Heaven, : and the Lost, "We were always in Hell." And both will speak truly.”

“Hell is a state of mind - ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind - is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself. All that is fully real is Heavenly. For all that can be shaken will be shaken and only the unshakeable remains.”
