The great difficulty in the use of the Bible has come from wrenching it from this main purpose. Confusion is sure to arise whenever any volume is employed apart from its primary intent. If one wishes to learn mathematics, and his foolish teacher shall give him a book of music, the result is not edifying. The pages of the book may be properly numbered, and the scales of music may be denoted by the correct fractions; but mathematics represents a thoroughly subordinate purpose, and the volume does not lead easily on to Calculus. The result is even more confusing if the arithmetic be handed to a pupil who wishes to study versification. The multiplication table may look like verses when seen at some distance; still the arithmetic's main intent is not the teaching of poetry. The illustrations of possible confusion could be taken from all fields. The common sense of the race saves it from the blunder of misapplying the most of its books. The Bible, however, has been subjected to misapplication because the theory of its infallibility has often been made to cover a wide, not to say a universal, range. The student who goes to the Bible with a purpose that is mainly historical, or scientific, or geographical, or genealogical, or mathematical, or even poetical and literary, may not find all his wishes gratified. But the student who seeks its pages under a profound sense of God and with an equally profound will to do God's will is certain to find material for all his moral and spiritual ambitions.
