Dr. Latourette who has served thirty years as Professor of Missions and Oriental History at Yale is the recognized authority on the history of Christian Missions, being widely known as the author of A HISTORY OF CHRISTIANITY and a seven-volume HISTORY OF THE EXPANSION OF CHRISTIANITY. He does not abandon the role of the historian in the present book, for it is against the background of a review of ""The World of Yesterday"" and the spread of the Gospel that he paints his picture of ""The World of Today"" and the spread of the Gospel in it. In this age of storm, characterized by wars and rumors of war, by the spread of communism and the uprising of long suppressed peoples, Christian leaders are rightly troubled. China is closed to missionary endeavor, there are uprisings in Africa and a new ferment in India. No wonder, Latourette and other leaders of the churches are asking ""What is in store for the church in mission lands?"". The book calls for a re-examination of the philosophy and techniques of the missionary endeavor. Latourette is a well known writer in Protestant circles and the urgency of the subject gives this book special appeal.
