And now Korihor said unto Alma: If thou wilt show me a sign, that I may be convinced that there is a God, yea, show unto me that he hath power, and then will I be convinced of the truth of thy words.

But Alma said unto him: Thou hast had signs enough; will ye tempt your God? Will ye say, Show unto me a sign, when ye have the testimony of all these thy brethren, and also all the holy prophets? The scriptures are laid before thee, yea, and all things denote there is a God; yea, even the earth, and all things that are upon the face of it, yea, and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator.

Alma takes Korihor’s own philosophy and catches him in a trap of his own making. Korihor teaches that we can know only what we can see. (See Alma 30:15.) But when questioned, Korihor categorically denies that he believes there is a God. Alma then asks, “What evidence have ye that there is no God, or that Christ cometh not? I say unto you that ye have none, save it be your word only.” (Alma 30:40.)

It is an inspired insight on Alma’s part. Korihor is not consistent in his own thinking. If we truly can know only those things for which we have empirical evidence, then we cannot teach there is no God unless we have evidence for that belief. And Korihor has no evidence.

Korihor will consider only evidence that can be gathered through the senses. In such a system, it is much easier to prove there is a God than to prove there is not a God. To prove there is a God, all it takes is for one person to see, hear, or otherwise have an experience with God, and thereafter the existence of God cannot be disproved.

When I was preaching in Philadelphia, a Quaker called out for a sign. I told him to be still. After the sermon, he again asked for a sign. I told the congregation the man was an adulterer; that a wicked and adulterous generation seeketh after a sign; and that the Lord had said to me in a revelation, that any man who wanted a sign was an adulterous person. “It is true,” cried one, “for I caught him in the very act,” which the man afterwards confessed when he was baptized. (Feb. 9, 1843.) DHC 5:268.
