A good friend recommended this book to me some time ago, but mentioned it was hard to find, so I was very excited when I came across a copy at a church sale last fall. I consider this one of the best teaching books I've ever read, and one I'm sure I'll keep coming back to in the future. It's a fairly short, but extremely powerful treatise on prayer, a topic absolutely central to the Christian life, but too often sadly neglected.
For starters, I am very impressed that the author chose to remain anonymous. This was quite an unusual choice (almost unheard-of, in fact, as far as I know) but it really contributes to the power of the book. Knowing that it was written, not for the fame, or financial gain of the author, but that the Church might receive the benefit of the teaching, and that God might be glorified, really amplifies the message.
In line with the author's humility in embracing anonymity, is his style of teaching, which I would describe as exceptionally meek and gentle. I have read teaching books where the doctrine was generally quite good, but was presented in a kind of "lecturing" tone, which I can imagine that more sensitive readers would find discouraging. Not so with this book: the author passes up every opportunity to "browbeat" his audience, bringing encouragement, instead of condemnation.
On the whole, I felt that the author did an excellent job of clearly showing us prayer for what it truly is: the conversation of a child with his Father. If only we would learn to come to God in this way, in simple faith, without formulas and preconceived notions, I honestly believe we would find the results to be utterly amazing.
