In the first place, attention may be called to the essential unity of the book. There are in the Old World great and magnificent cathedrals, some of which have been centuries in building, yet in all of them may be found unity and harmony. How is this to be explained? Although generation after generation of workmen have labored on the enterprise, back of all the efforts was a single plan, evolved in the mind of one man, which mind controlled all the succeeding generations of workmen. The result is unity and harmony. The Bible has been likened to a magnificent cathedral. The phenomenon to which reference has been made in connection with ancient cathedrals may be seen in the Bible as a whole, as also in the Old Testament considered separately. The latter contains thirty-nine books, by how many authors no one knows, scattered over a period of more than a thousand years, written, at least some of them, independently of one another, in places hundreds of miles apart. And yet there is one thought running through them all--the {30} gradual unfolding of God's plan of redemption for the human race. There must be an explanation of this unity. Is it not natural to find it in the fact that one and the same divine spirit overshadowed the many men who made contributions to the Book? The proof of the presence of a divine element in the Old Testament which is derived from the essential unity of the book, is confirmed by the response of the soul to its message, and the effect which it produces in the lives of those who yield themselves to its teachings. Jesus and his disciples observed that its message rightly applied would awaken a response in the human heart; sometimes, indeed, it produced a sense of indignation, because it carried with it a sentence of condemnation; at other times it led to loving obedience. And they themselves experienced the effects of its teaching upon life and character: it was with truths proclaimed in the Old Testament that Jesus overcame temptation, and the quotations used in the darkest hours of his earthly life are an indication that at all times he found the most refreshing soul food in its pages. The same is true of the early disciples of Jesus. Undoubtedly, the statement in 2 Tim. 3. 15-17 is the expression of a living experience; and ever since these words were written millions of Christians have experienced the uplifting influence of many portions of the {31} Old Testament Scriptures. They may not enjoin the finer graces of Christianity, but they insist most strongly and persistently upon the fundamental virtues which go to make up a sturdy, noble, righteous, uncompromising character. A message which produces such divine results bears witness to itself that it embodies truth which in some sense proceeded from God. This is aptly stated by Coleridge in these words: "Need I say that I have met everywhere more or less copious sources of truth and power and purifying impulses, that
