This book by David Platt is absolutely a must read for every Christian. I absolutely love the subtitle: Taking Back Your Faith From The American Dream! Not only does it challenge the importance on "stuff" in our lives but it will also challenge you to share your faith, not only with those around you but around the world as well! Part of the challenge presented by the book is also to pray for every country in the world so on top of everything else, your prayer life should be improved and increased after reading this amazing book.
