Book excerpt: Thousands of Protestant churches are perplexed by plateaued or declining attendance, while other congregations nearby thrive. Is there a way for them to combine forces, drawing on both their strengths, in ways that also increase their missional impact? Church merger consultant Jim Tomberlin, with co-writer Warren Bird, makes the case that mergers today work best not with two struggling churches but with a vital, momentum-filled lead church partnering with a joining church. In this new book, they provide a complete, practical, hands-on guide for church leaders of both struggling and vibrant churches so that they can understand the issues, develop strategies, and execute a variety of forms of merger for church expansion and renewal to reinvigorate declining churches and give them a "second life."
