South Ridge Worship provide a useful study guide through C.S. Lewis’ book the Great Divorce. The Great Divorce is a novel, in a similar vein to The Screwtape Letters which is probably my favourite C.S. Lewis book.
As well as a short introduction there is a selection of question sheet for the chapters, and also links to the sermons that were preached alongside the study of the book. If you enjoy The Great Divorce, then this could be a great way to dig even deeper into it.
If you enjoy this you may also be interested in other free C.S. Lewis resources.
Thank you to Langdon Palmer for suggesting the link!
