Staff members are held accountable for growth resulting in new people, as well as meeting the needs of those already involved in their particular ministry. The more pagan our culture becomes the less open people are to visiting our church on Sunday morning. In many churches Sunday morning is no longer the main door through which visitors come. Instead it may be a small group, a ministry team, a sports team, a recovery group, building a home in the community, etc. Churches create varieties of ways for unchurched people to connect with churched people in order to develop relationships.
People come and stay because of the relationships.
Most churches stay small because they start and then remain as a single cell organization. This single cell may become stretched but it eventually closes and new people do not feel welcome. Visiting many small churches is like attending the family reunion of a friend. Churches must intentionally work at incorporating new individuals. It is not something that happens automatically.
