Jesus, speaking to His disciples, taught that "the Comforter, which is the Holy Ghost, whom the Father will send in my name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."[A] This clearly implies that the promised gift is essentially a gift of increased intelligence with the added power that results from a more intelligent action. That this is the Mormon view of the effect of the Gift of the Holy Ghost may be amply demonstrated from the standard works of the Church and from the writings of the leading interpreters of Mormon doctrine. Parley P. Pratt in the Key to Theology says, "It quickens all the intellectual faculties, increases, enlarges, expands and purifies all the natural passions and affection * * * *. It develops and invigorates all the faculties of the physical and intellectual man."[B] The Prophet Joseph Smith declared "This first Comforter or Holy Ghost has no other effect than pure intelligence. It is * * * * powerful in expanding the mind, enlightening the understanding, and storing the intellect with present knowledge."[C] Concisely expressed, therefore, Joseph Smith and the Church he restored, teach that the Gift of the Holy Ghost, is a gift of "intelligence." [Footnote A: John 14:26.] [Footnote B: Key to Theology, 5th ed., pp. 101, 102.] [Footnote C: History of the Church, Vol. III, p. 380.] [Sidenote: Science furnishes an equivalent of the gift of the Holy Ghost.] If the equivalents of faith, repentance and baptism are irrevocable laws for the individual who studies science, the question arises, Is there also, a scientific equivalent for the Gift of the Holy Ghost? Even a superficial view of the matter will reveal such an equivalent. To use again the illustrations employed in the preceding chapter, if the chemist has obeyed natural law in producing hydrogen, that is, has been baptized into the kingdom of hydrogen, he may by the proper use and study of the gas obtained, add much to his knowledge. He may learn that it is extremely light; that it forms an explosive mixture with air; that it will destroy many vegetable colors, and will burn with an almost invisible flame. Thus, the possession of the gas enlarges the knowledge and develops the intelligence of the scientist. Is not this another form of the Gift of the Holy Ghost? The man who is baptized into the kingdom of heavenly bodies by grinding the lenses right, is enabled to learn many new facts concerning the nature and motions of celestial bodies; and thus receives intelligence. He who obediently winds the wire correctly around the iron core, may generate a current of electricity with which many mighty works may be accomplished. Do not these men, as their intelligences are expanded, receive a Gift of the Holy Ghost, as a reward for their obedience to the demands of nature?
