This digital-only e-book provides foundational material on adaptive leadership for the church. It is for seminary students, people training for ministry in other settings, and local church leaders who are striving to understand the biblical and theological underpinnings of adaptive ecclesiology. These readers will also gain knowledge about how this approach has worked historically, and how it is used inside and outside the Church today. The authors' main book on the topic, Gardens in the Desert: How the Adaptive Church Can Lead a Whole New Life, is more practical in its focus, helping pastors and other leaders know how to begin shifting toward adaptive ecclesiology in their own local churches. The Adaptive Ecclesiology digital-only e-book is a deeper look at the foundations of the topic.
