Rediscovering the role God designed for the church in mission is a critical issue facing the missions movement today. That role is to glorify God by planting churches among every tongue, tribe, and nation. Planting churches amid unreached peoples is a complex process. It calls forth every ministry gift and the contribution of every believer. Imagine a businessman, a construction worker, a schoolteacher, and an engineer all working together to support the development of a local church amongst an unreached people group in another part of the world. Most Christians will not leave home and go elsewhere to minister. If they are to participate in God's global mission, they must be affirmed, developed and released right where they live, in the context of their local church. This book shows how churches can become centers of mission vision and implementation and so accomplish God's design for the local church.
