Unfortunately, for many churches and Christians, evangelism and missions is an appendix rather than a core component of their task. Such churches tend to be precautious rather than prevailing, busy preserving the faith within, not propagating it without. Precautious churches know little about taking risks and a lot about minimal survival. They exist largely to meet the needs of church members. For them community means the church is a subculture that is closed to outsiders. Lost people are neither pursued evangelistically nor welcomed enthusiastically.
