Inaccuracies may be due to the revision and editing, and not to the translators, for every good translation must be fluent and idiomatic, to secure which is the most difficult task. Pastor Gohdes also rendered valuable help in the final revision of parts. The translation of the analyses is by the undersigned. The few last pages of the first edition of volume one we revised and reprint in this volume in order to make the pages of each volume of our edition to correspond with the German and Latin volumes of the Erlangen edition. The paragraphs are numbered and the analyses given according to the old Walch edition. _Luther and World-Evangelization_. In translating Luther into practical English in practical America, and in this age that is growing more and more practical, we need to be reminded that this work is for practical use and purposes. Luther was radical along Bible lines in applying the truth personally and to the world. It is a year since the last volume of the "American Luther" appeared. The delay was caused by an effort to raise the work to a higher standard and by the publication of a book on "The True Place of Germans and Scandinavians in the Evangelization of the World", not a revision of, but a new companion volume to "Lutherans In All Lands" that appeared seventeen years ago. By comparing these two books one has the best evidence of the marvelous progress of God's Kingdom in recent years, and the growing world-significance of Luther's evangelistic writings. Evangelization at home and abroad is the popular religious theme today in the German fatherland and in the whole Protestant world. The word "world" is becoming so common its full meaning is not appreciated. When world-evangelization is discussed, it is too often from the standpoint of the nation discussing it. Each nation is so active in its own work that it fails to appreciate what others are doing. For example how little the world missionary conferences in English lands have to say of the German and Scandinavian missions and the Reformed Churches of the Lutheran work. Hence the fruits of Luther's evangelical writings are underestimated by the English people. It is opportune to translate not only Luther but also the best fruits of those writings in various languages during the past 400 years, especially since the memorable date of 1917 is soon to be celebrated by universal Protestantism. Luther in all languages and Lutherans in all lands go together. We ought to consider most carefully the great Reformer in his relation to the modern world and modern world-evangelization. The known world in his day was not so large. He had, however, a clear view of it all in his writings, which is due to his faithful study of the Scriptures. The Bible gave him a knowledge of the world, including all lands and all times. His commentary of eleven volumes on Genesis illustrates this. The first volume on Genesis treats of the first part of the ancient world; the
