This series of lectures is to be placed among the most important writings of Dr. Saphir. Here he gives us his matured views of the relation of the two great divisions of the Bible. The reader is given an insight in the deep meaning of the symbols and prophecies of the Old Testament, as well as of the narratives of the New. He most clearly proves and strikingly illustrates the unity of teaching in both covenants. Few preachers or writers of our day have such a clear insight into the spirit and connection of the sacred writings.
