The triteness of the title of this little book should not dissuade the potential reader from proceeding further. In short compass, the widely known Australian Methodist missioner has put together a cogent picture of the urgency of the evangelical task of the churches today, and some of the possible means that might be employed in its pursuit. He is thoroughly conversant with the mass, impersonal character of contemporary society, and his call to evangelism is something different from what the traditional implications of this term might suggest. Among indicative chapter headings are these: The Winning of Mass Man, The Primacy of Proclamation, Faith for the Teenager, The Atomic Power of the Laity, The Mass Communication of a Personal Gospel, and others. A stimulating addition to current literature on the renewal of the Church and of its mission.
