The document discusses implementing a five-fold leadership model in churches based on Ephesians 4:11, consisting of apostles, prophets, evangelists, shepherds, and teachers (APEST). It argues that most churches only focus on shepherds and teachers, neglecting the other roles. A mission-oriented church requires all five types of leadership to function at its best. The author's church, Mosaic, is restructuring its leadership team to represent each of the five roles of APEST in order to make the church more effective in its mission.
