Evangelism represents a clear point of weakness. This isn't to criticize passion in belief. However the moment you need to recruit members to increase size and believe or behave as you do - something has gone off track. I have a hard time believing that making a disciple involves some sort of intentional bbq in my backyard or knocking on someones door with an agenda for a particular conversation that is anything but personal. Discipleship happens when someone is really good and really passionate about what they do - then people follow because what they do is worth following.
