The past two decades in Christendom have brought forth a proliferation of books about church planting. One denomination (Southern Baptist) has even set a goal to start fifty thousand new churches over the next twenty year period. But what's missing toward that end is a solid resource that specifically defines how one established church can successfully sponsor or parent a new church into sustainable existence. Spin-Off Churches aims to meet that need with contributions from a team of veteran missional church planters whose access to current church sponsorship data through the North American Mission Board is second to none. Their experience and teaching will guide readers through the church sponsorship process from its biblical basis to the nuts, bolts, and resource basics of implementation and follow through.
