Biblically anchored, this book traces the historical development of the Christian mission, and discusses the structures and strategies needed to be practically relevant. Graphs, charts and personal illustrations add to the impact of this book. Johnstone identifies the challenges that the church faces in order to reach the world so that the Gospel can be considered by every person.

This volume is an indispensable companion to "Operation World", providing a framework to understand what God is doing in the world, and how you can be a part of that activity.
