In recent years, the mission of the church has been defined in two almost exclusive ways. On the one hand are those who say the church must focus on evangelism and discipleship alone. On the other hand are those who advocate concentrating almost solely on societal reform. In this classic book, John Stott shows that Christian mission must encompass both evangelism and social action. He begins with careful definitions of five key terms: mission, evangelism, dialogue, salvation, and conversion. Then, through a thorough biblical exploration of these concepts, Stott provides a model for ministry to people's spiritual and physical needs alike. Ultimately, Stott points to the example of Jesus, who modeled both the Great Commission of proclamation and the Great Commandment of love and service. This balanced, holistic approach to mission points the way forward for the work of the church in the world.
