"For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart." (Heb. 4:12)

By the aid of a new scientific instrument, the ophthalmoscope, with its condensing mirror and myriad of little lenses, the ophthalmologist can look into a person's eye and not only determine approximately the necessary strength of glass required to give perfect vision, but also the existence of tumors pressing on the brain tissue, the conditions of the general nervous system, the presence of disease in various organs, and the richness of the blood current as the are clearly traced on the sensitive plate of natures's camera. (From Illustrations of Bible Truths, p. 10)

What the ophthalmoscope is to the ophthalmologist, the word of God is much more to our higher nature. The word of God has the vitality and power to determine and repair our spiritual health. Let us study and meditate on it daily because it has the ability and power to mold us into what we ought to be.
