This book is definitely a difficult read. You need to have a wide knowledge of theology, philosophy, and history to keep up with Chesterton! It has taken me a long time to read it little bit by bit, but it has been worth it! The content is so deep and inspiring that you need time in between chapters just to digest everything you've read. There were many things I did not understand, but I just kept going and cherished the amazing sections that I did understand. There are some wonderful quotes in this book, and Chesterton's writing is never boring!
I do not recommend it for new Christians, but anyone who has read C.S. Lewis might enjoy Chesterton too; although, Lewis wrote for the common man, and Chesterton writes for the scholar.
