says that the change in a congregation's size has more of an impact on their sub-culture than denominational distinctives. As the church grows there is less of a close-knit everyone pitching in family style feeling. The middle stage, where most evangelical churches are, is one that requires structures and routines that in a small gathering would seem artificial and out of place. The larger churches, says Keller, that require more staff or multiple services, change the culture of the congregation yet again. SOUL has just changed from being a small tightly knit church plant into a growing sapling with lots of people coming and going. So that I can concentrate on preaching, prayer, training and strategy we adopted the "person" model of ministry, also described as the overseer model. Instead of centrally managed rosters, we empower people who are passionate about a particular area of ministry, for example welcoming or music, to build up a team and be responsible for that area of SOUL church. The difficulties will be in finding people for less glamorous ministries (for example setup and packup) and being relaxed about things occasionally falling down (for example the person responsible forgets to lock the building). Another challenge is finding the right people, they need to both responsible and motived enough to recruit a team and eventually a replacement.
