For the short period of time that it lasted, The Welsh Revival was, in many ways, the greatest that the church has ever witnessed. Never has a region been so quickly or radically transformed for righteousness, or the world so impacted. The fire of this revival was so intense that when letters or newspaper stories about it were read in other parts of the world, revival would break out there too. Today, almost a century later, those who just read or hear the story are still moved with conviction, hope and the inevitable question: Will God do it again? Yes! The purpose of this book is to review the events and lessons from one of the greatest moves of God of all time, in order to prepare for one that is even greater.
