Another great deal!!

We're on a roll here! Desiring God Ministries is offering John Piper's new book The Future of Justification: A Response to N.T. Wright for $5!! Over the last several months, I've seen lots of blurbs (positive) on this book. If you're into theological issues in the church, this book is a must have. However, in a recent 9Marks interview British scholars, Simon Gathercole and Peter Williams, when pressed by Mark Dever admitted that if you are a pastor unaware (or dispassionate) of the New Perspective on Paul controversy, there really is no need to start studying it (unless, of course, it starts becoming an issue in your church). White Horse Inn had a broadcast about a few weeks ago on Current Controversies over Justification. Do you guys have any thoughts on the NPP?
