What is the most potent force shaping the destiny of mankind today? The sense of heritage, replies this noted author. But what heritage shall be selected from yesterday? The answer to that puzzling question is given in this thought-compelling book. The purely forward view has broken down today, and we must look backward for our creative pattern of life. Mankind, Dr. Mackay maintains, can only get a fresh start by a rediscovery of the past. When God, coming in the Great Tribulation, is chosen as the chief heritage of humanity, then men will fulfill their true destiny in personal, cultural, and national life. Here is a timely, yet timeless, Christian appraisal of intense interest for all readers.
