This book is poorly, at times incoherently, written. It is often difficult to understand what the author is trying to say. It appears to be the ramblings of a confused mind. One wonders if English is his native language since he uses it so ineptly.
While it is difficult to make sense of much of what he is writing, he seems to be denying many basic Christian beliefs with cherry-picking and long-discredited arguments.
To say that the book is poorly reasoned would be to praise it too highly. There is no logic in it whatsoever.
I strongly recommend bypassing this book. Reading it would be a total waste of time.
