This is an old classic whose premise is that the reason Christian fail to succeed spiritual is their failure to pray. It is the authors belief that most Christians have lost the wonder of their faith, that deep down inside they really do not believe we worship an omnipotent God who is capable of given us exceedingly abundantly above all we think and ask. The bottom line is this: do we believe God's Word is true?
The author has unwavering faith in the claims of Scripture. He believes that the scriptural pronouncements concerning prayer are to be taken literally. Our failure to do so is the root of the churches inefficiency and powerlessness in the world. In this, the author has hit the proverbial nail right on the head. The author is to be commended for stating that not only are we to pray, but that our prayers are to have meat on them. Do we really believe in an omnipotent God? Our prayer life betrays us.
Unfortunately, this book is written in a style that is difficult to read, peppered with undocumented illustrations, making it difficult for this reader to complete the book. It was very discouraging to read of these prayer warriors of almost mythical proportions with the authors underlying assumption that we too should be like them. Who were they? What is the documentation? Living in a far more cynical age, these questions need to be answered. Although the author specifically states that prayer is hard work, he seems to assume that if our faith was a great as these nameless missionaries we too would experience mountain moving prayer.
I could not help but contrast this attitude with the humanity portrayed in Bill Hybells books on prayer. With Hybells you see a flawed man discovering the power of prayer, with the Unknown Christian we are confronted with dozens of supersaints whom we must try to emulate.
There are better books out there. It may be a classic, but it is a dated classic.
