Book excerpt: ÒIt is one of the principle tasks of the theologian in each generation to bring the preaching of the church to the bar of the word of God and to test its adequacy as a faithful presentation of the message and teaching of the New Testament . . . If this book can help evangelists to rethink the content of their proclamation in order to let the Word of God have free course in their ministry . . . it will amply serve the purpose of its publication.Ó - From the author's Preface
