12 - Book of Revelation
This book of the Bible is the most challenging - it may seem absurd to the material mind, but to the spiritual which does not rely on a materialistic view, this book is awesome - depicting the ultimate war of the flesh against the spirit, the steps required, the utter destructon of the unGodlike, and the ultimate victory, or realization of reality - "a new heaven and a new earth." Listening to the entire book is a powerful experience.
Bible Storytelling
