Since the world mission of the church is a divine imperative, a review of the situation is in order from time to time, but at such a time as this, when the world has grown so small with inevitable conflict between western and primitive cultures intensified, an objective review and evaluation is demanded. Eugene L. Smith, the General Secretary, Division of World Missions of the Board of Missions of the Methodist Church, is well qualified to make such a study, and his review of God's mission and ours is both historically and theologically satisfying. He answers such questions as ""Are missions essential to the life of the Church? What is the real source of power in the Christian Mission? What problems must be faced owing to the conflicts that exist between western and primitive cultures?"", etc. Protestant ministers, students and earnest Christian laymen will find this a valuable resource book for mission study.
