Philip Yancey & Prayer: Does it make a difference?

Yip I have completed the book and really enjoyed this devotional and challenging book. The book is birthed from feedback of readers of his previous books that have struggled with this issue of prayer. In fact in this book contains various letters about readers who have wrestled with prayer.
Philip does not set out to be an expert in prayer. In fact probably finds himself in the same boat as the reader. He too struggles with prayer. He doesnt have all the answers. So often we want these straight answers and quick fixes.
I feel that Philip definiely makes us think about these things we dont understand about prayer.
He even talks about unanswered prayerand reminds us that Jesus were seemingly not answered - Jesus had asked that if it be his will the cup be removed from him if it were to be the Fathers will. The biggest impression was that it is okay to be honest or even wrestle in prayer. I didnt just feel like I was reading a dry book on prayer but a book that spoke and gave me a fresh perspective on prayer..
