The following words of Stephen Neill are used to introduce chapter 1: “If everything is mission, nothing is mission.” The chapter wants to introduce the concerns of questions like, What is the mission of the church? Is the mission of the church the same as the mission of God? Should we distinguish between the mission of the church and the responsibilities of individual Christians? Is Jesus’ mission continued by the church? Is it part of the church’s mission to pursue social justice? Is the church to build the kingdom of God? What is meant by modern uses of the word “missional” to describe the church and how should we evaluate them?
