It is greater than the First and Second Great Awakening and every revival in our country combined...but in the opposite direction.” This is the conclusion of the largest and most comprehensive study of dechurching in America by sociologists Ryan Burge and Paul Djupe. In The Great DeChurching, pastors Jim Davis and Michael Graham unpack why and how over the past twenty-five years, forty million of those who formerly attended church no longer do so.
