The key to a biblically successful church is not how many people you can gather together, argues J.D Greear; the key is how many you can send out on mission. In his new book Gaining by Losing Why the Future Belongs to Churches that Send (Zondervan), Greear offers counsel to church leaders in reorienting their churches toward a focus on training disciples and sending them out to serve. This book will help readers recognize the symbol of church success is not seating capacity but sending capacity.
