CS Lewis's "The Great Divorce" has an amazing picture of heaven (new creation). It grasps the world to come with poetry and story, and not simply abstract concepts. Surely this is a good lesson for all our theology!
"I had the sense of being in a larger space, perhaps even a larger sort of space, than I had ever known before: as if the sky were further off and the extent of the green plain wider than they could be on this little ball of earth. I had got 'out' in some sense which made the Solar System itself seem an indoor affair. It gave me a feeling of freedom, but also of exposure, possibly of danger, which continued to accompany me through all that followed." (p.20)
"It was the light, the grass, the trees that were different; made of some different substance, so much solider than things in our country that men were ghosts by comparison..." (p.21)
"...all loneliness, angers, hatreds, envies and itchings that it [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." (p.138)
