Throughout the entire book these and other {26} indications of the presence of a human element may be seen, which the reader cannot afford to overlook if he would estimate rightly the Old Testament Scriptures. But while they are there, they must not blind the eyes of the student to the fourth great truth expressed by the writer of the Epistle to the Hebrews, namely, that God spoke through these men; in other words, that there is also a divine element in the Old Testament. In the words of S. I. Curtis: "While it seems to me that we find abundant evidences of development in the Old Testament from very simple concrete representations of God to those which are profoundly spiritual, I am not able to account for this development on naturalistic principles. In it I see God at all times and everywhere coworking with human instruments until the fullness of time should come"[3]. The presence of this divine element was recognized by Jesus and by all the New Testament writers, and surely it is a significant fact that in the first outburst of Christian enthusiasm, and under the living impression of the unique personality of the Master, no doubt arose concerning the inspiration and permanent value of the Old Testament. With the Christian the testimony of Jesus and his disciples carries great weight. But without appealing to his authority every unbiased reader may convince himself of the nature and character {27} of the Book; it is not necessary to depend upon the testimony of men who lived centuries ago, though they were inspired men. The Book is an open book, ready for examination, and inviting the closest scrutiny on the part of every reader.
