The Brother of Jared Is Taken within the Veil and Shown Things He Is Forbidden to Show to Any Man
Ether 3:18–21
18 And he ministered unto him even as he ministered unto the Nephites; and all this, that this man might know that he was God, because of the many great works which the Lord had showed unto him.
19 And because of the knowledge of this man he could not be kept from beholding within the veil; and he saw the finger of Jesus, which, when he saw, he fell with fear; for he knew that it was the finger of the Lord; and he had faith no longer, for he knew, nothing doubting.
20 Wherefore, having this perfect knowledge of God, he could not be kept from within the veil; therefore he saw Jesus; and he did minister unto him.
21 And it came to pass that the Lord said unto the brother of Jared: Behold, thou shalt not suffer these things which ye have seen and heard to go forth unto the world, until the time cometh that I shall glorify my name in the flesh; wherefore, ye shall treasure up the things which ye have seen and heard, and show it to no man.
Elder Bruce R. McConkie wrote:
“In the eternal sense, because faith is the power of God Himself, it embraces within its fold a knowledge of all things. This measure of faith, the faith by which the worlds are and were created and which sustains and upholds all things, is found only among resurrected persons. It is the faith of saved beings. But mortals are in process, through faith, of gaining eternal salvation. Their faith is based on a knowledge of the truth, within the meaning of Alma’s statement that ‘faith is not to have a perfect knowledge of things.’ . . . Men have faith when they ‘hope for things which are not seen, which are true.’ In this sense faith is both preceded and supplanted by knowledge, and when any person gains a perfect knowledge on any given matter, then, as pertaining to that thing, he has faith no longer; . . . it has been supplanted by pure knowledge.”
