When a strong Christian reads PDL, there is not doubt that they will find it weak and less than spiritually nurishing. But, when one who is weak in the faith or with out Christ reads the book, it is a stimulus to spiritual growth. I have heard too many stories from reliable sources (i.e. people I trust) about the use of the book to cause people to realize their need for Christ and receiving Him as saviour. Also, I have seen weak in the faith Christians started down the road to moving to the meat of the Word because the book helped them jump start their stagnent growth process. In all, it is a good book and worthy of the use that it is getting. If you don't like it, don't use it. But don't throw rocks at those who do like it.
