The Old Testament makes for itself, implicitly, and explicitly, the claim that it is the witness, in literary form, of the people who knew the one true God. That claim, says the author, the Rev. Dr. Harvey H. Guthrie, Jr., Assistant Professor of Old Testament at the Episcopal Theological Seminary, Cambridge, Mass., is his concern as he asks the questions ""How and where and as whom has God made himself known?"" God is the one who makes himself known in concrete things he has done, and the Old Testament is the story of these acts. That God mas made himself known in world history as the living Lord of history and the world in which history takes place. Moreover, the writers were sure that the one who had revealed himself as God in the events of olden times was also reigning in their times. This book makes excellent reading, and the author relates his subject well to modern thought. Bible students and teachers will find it one of the best current books on the Old Testament.
