Interest in small group experience has greatly increased in and out of the churches in recent years. It has been characterized by a wide expansion of various sorts of group activities in the churches and by the rapid accumulation of a specialist literature dealing with research and theory about group dynamics. A vacuum has come into being, however, in the area of literature intended for the novice and amateur group member. Dr. Reid's book provides a concise, clear introduction to the basic principles underlying group experience and to some of the practical procedures by which groups can carry on. The theoretical statements are soundly based in the advanced literature in the field and the practical applications clearly and engagingly illustrated by cases and by the author's own experience as a group participant and leader. The contract between group members, the dynamics of group behavior, the role of the leader and of the individual member, and common problems confronting groups are among the topics discussed. This book should attract a wide readership among pastors as well as lay people interested in groups. It should help make both phrases in the title come alive.
