This leads to growth. Healthy small churches grow. Growth can affect the relationship networks within the church, and because of that, some members may resist growth. They do not want new people taking the pastor's time away from them. They do not want new people taking ministry roles away from them.
Growth means change, and some people have a low tolerance for change.
Change means conflict. But a refusal to change means slow death. If we want our church to survive, we must be willing to change. It is generally through personal relationships, through members inviting friends and relatives to church. People may be invited for special programs, or simply for a weekly worship service, but the invitation begins with a relationship.
