What is the church's work of missions, and how should we carry it out? In this thorough study, Eric Wright roots missions solidly in the biblical text while giving modern, real-life examples of how missionary principles can be applied practically. He covers subjects such as missions and God's kingdom, the validity of mission boards, the role of providence, the necessary spiritual gifts, the multi-ethnic nature of ideal churches, how to avoid dependency, the priority of church planting versus humanitarian ministries, and short-term versus life-long missionary commitment. This book reverses the drift away from theology into pragmatics, without denying the importance of a dynamic methodology that responds to changing conditions. Regular snapshots of missionary life as it is being or has been played out in real situations ground the whole book in reality.
