During the past generation the Old Testament has commanded equally with the New the enthusiastic and devoted study of the great body of biblical scholars throughout the world. Two out of every three graduate students in our universities who specialize in the general field of biblical literature choose the Old as the special centre of their work. At the same time the tendency of the rank and file of the Christian church within the past decade has undoubtedly been to neglect the older Testament. Preachers as a rule select less than a fourth of their texts from it; the prevailing courses of Bible study devote proportionately less time to it; and teachers and scholars in the great majority of cases turn to the Old Testament with much less enthusiasm than they do to the New. Why are these two great currents setting in opposite directions, and what are the causes of the present popular neglect of the Old Testament? If the Old Testament should be relegated to a second place in our working canon of the Bible, let us frankly and carefully define our reasons. If, on the other hand, the prevailing apathy and neglect are due to ignorance of the real character and value of the Old Testament, let as lose no time in setting ourselves right. The present volume has been suggested by repeated calls from ministerial bodies, popular assemblies, and groups of college students for addresses on the themes here treated. The aim has been to give in concise, popular form answers to some of the many questions thus raised, with the conviction that they are in the mind of every thoughtful man and woman to day, and especially on the lips of earnest pastors, missionaries, and Sunday school teachers.
