The first detailed exegetical treatment of Paul's letters from the emerging discipline of missional hermeneutics, this book argues that Paul's letters invite Christian communities both then and now to not merely believe the gospel but to become the gospel and, in doing so, to participate in the life and mission of God. Showing that Pauline churches were active public participants in and witnesses to the gospel, the author reveals the missional significance of various themes in Paul's letters. He also identifies select contemporary examples of mission in the spirit of Paul, inviting all Christians to practice Paul-inspired imagination in their own contexts.
