Kevin Smith "The Great Divorce concept"

The Great Divorce is a book written by Clive Staples Lewis, a prominent christian author. In the book there is a main character who joins a group of people. They are shuttled from a gray, obscure town in a flying bus, to a land that is supposed to be the foothills of heaven. The foothills are a much brighter environment than they are used to. When they get there they all realize that they can't walk on grass and it is actually quite spiky and it hurts their feet. While there they realize they are actually all ghost. They then encounter angels who are friends from their past lives. The book is the main character following each ghost individual and their interactions with their angel friends. The angels actually try to convince the grumpy ghost people to follow them on towards "heaven", but almost every ghost is reluctant and hesitant and scared. It's such an interesting book and I recommend it for anyone. What's interesting is that the ghost could not literally enter heaven without help from the angels. They also couldn't really walk on the grass. Every single part of the environment is hard to them. It's kind of like how we talked about in class how a person may enter a place, but not completely experience it and take it in.
