John Stott's aim is to examine the biblical meaning of some of the great key words which are at the center of the contemporary debate about Christian mission. In that debate, the interpretation of mission which is popular in some circles within the ecumenical movement differs acutely from that which has been held traditionally by many evangelicals. The way forward is for the two sides to meet together in joint study of the Scripture, and to correct and enrich their own and others' understanding of mission by a deeper understanding of the biblical missionary theme and a fuller submission to it. Four adjectives describe this book: biblical, clear, fair, constructive. - Foreword.
