If you saw a missional church, what would it look like? What patterns of behavior and practice would you find there? Building on the ground laid by the book Missional Church (Darrell Guder et al.), this volume centers on case studies of nine missional congregations from across North America that are diverse in their denominational affiliations, worship styles, political stances, and socioeconomic backgrounds. Treasure in Clay Jars explores eight concrete 'patterns' common to these churches. Although the patterns may be different in each setting, they can be recognized in any congregation seeking to participate in God's mission in the world. The congregations studied here are 'clay jars,' but each carries in its respective witness a remarkable treasure that points to God's power and purposes.
