Query: only for those with very strong Christian beliefs

With all due respect to the author's intended audience, I have to point out that the book seems to be meant for those whose religious beliefs are specifically strong, perhaps even fundamentalist, Christian. I'm posting this review only so others considering buying it can know that, whether it persuades them to buy it or not to buy it.When I read the reviews as I was considering it, I was very interested, but might not have bought it, had I known how deeply Christian its foundation is, since the person I was buying it for is quite spiritual but of a different faith.
