Western society is now a very different, very difficult mission field. In such a situation, the mission of evangelism cannot succeed with an attitude of "business as usual." This volume builds a theology of evangelism that has its focus on the church itself. Darrell Guder shows that the church's missionary calling requires that the theology and practice of evangelism be fundamentally rethought and redirected, focused on the continuing evangelization of the church so that it can carry out its witness faithfully in today's world. In Part 1 Guder explores how, under the influence of reductionism and individualism, the church has historically moved away from a biblical theology of evangelism. Part 2 presents contemporary challenges to the church's evangelical ministry, especially those challenges that illustrate the church's need for continuing conversion. Part 3 discusses what a truly missional theology would mean for the church, including sweeping changes in its institutional structures and practices. Written for teachers, church leaders, and students of evangelism, this volume is vital reading for everyone engaged in mission work.
