The writer of this book has no difficulty in believing that the Bible contains supernatural elements. He is ready to affirm that other than natural forces have been employed in producing it. It is to these superhuman elements in it that reference and appeal are most frequently made. But the Bible has a natural history also. It is a book among books. It is a phenomenon among phenomena. Its origin and growth in this world can be studied as those of any other natural object can be studied. The old apple-tree growing in my garden is the witness to me of some transcendent truths, the shrine of mysteries that I cannot unravel.
