THE substance of these chapters has been given in various Bible Readings. Their object is not so much to attempt an explanation of the individual types, on which so many volumes have already been written, as to arouse interest in the study as a whole, and to emphasize the importance of comparing one with another. Not only does this method seem the surest way of arriving at the meaning of the separate types, but it is valuable as affording evidence of the presence of one Spirit inspiring the whole.
