What happens when churches from diverse denominations come together with a vision to join forces to reach the fourth-largest U.S. city? In this insightful book, Bruce Wesley, founder of the Houston Church Planting Network, shares how collaboration has meant everything to this effort to multiply churches throughout the Greater Houston area. Wesley offers invaluable lessons about working together to reach a city. Key takeaways include: understanding the tensions between addition (growing your church) and multiplication (planting churches); five essentials of collaboration; the importance of story over strategy; sharing the mic with other leaders; why “showing up” is vital. HCPN also started the HCPN Church Planting Residency, a yearlong finishing school for planters that is the collaborative work of a dozen diverse churches in Houston.
