Wow, what a read. Although it was written in the 1970's, the message has not changed. I found it very interesting that the author talks about "new age religion" such as Scientology as a foreboding problem and alas some thirty years later, it has become a main stream religion, leading many people away from Christ. So it was fascinating to learn what concerned Christians then and how it has materialized into a full blown obstruction to the Truth now.
The latter half of the book I read with one hand while holding the Bible in my other. I was amazed at how many scriptures I had overlooked in my reading.
I would definitely buy this book again.
