"There is a reason so many movements in the Western church have failed in the past century: They are a car without an engine. A missional church or a missional community or a missional small group is the new car that everyone is talking about right now, but no matter how beautiful or shiny the vehicle, without an engine, it won’t go anywhere. So what is the engine of the church? Discipleship. I’ve said it many times: If you make disciples, you will always get the church. But if you try to build the church, you will rarely get disciples."
