Churches committed to following Christ's example want this world changed for the sake of eternity. While the supernatural piece of making that happen goes without saying, how does a body of believers do its part to be in that "sweet spot" where true spiritual transformation occurs? In Transformational Church, best-selling research authors Ed Stetzer and Thom S. Rainer survey fifty thousand churchesthen narrow the scope down to five hundred congregationsfor a qualitative answer. Their book, the most comprehensive study of the modern American church to date, contains a wealth of indispensable new data, nuanced insights, and how-to guidance, all centered on this key finding: "Transformational churches make disciples whose lives are being transformed by the gospel, so that people engage the culture around them for its ultimate transformation."
