This book is indeed interesting, some of the time. There are long stretches of paragraphs that are a bit of a struggle to read through, particularly the sections on psychology and postmodernism.
The most interesting passages are about the other major religions,how they came to be, and the influence they have on Christianity.
Now back to the reason I claim this book to be inconsistent. There are sections that expound on a "faith only" salvation, and how fundamentalist "cults" believe too much in a literal translation of the bible and salvation through "works." While these authors go to great lengths to show that faith is the only need for salvation, the second half of the book discusses declining morality in the world. If works are not necessary to Christianity, then why should morality be promoted? Wouldn't living a moral life be a "work?" I find it foolish to say that all you must do to be saved is believe and have faith. Why would the bible exist with all of those "rules and regulations", if faith alone was enough to save?
This book is otherwise a fine discourse on upholding your belief in an almighty God and His plans for His creation.
