Boyd K. Packer
"There was a test of faith involved, as the Lord asked: 'Believest thou the words which I shall speak?' (Ether 3:11. Italics added.) Interesting, isn't it, that he was not asked, 'Believest thou the words that I have spoken?' It didn't relate to the past. It related to the future. The brother of Jared was asked to commit himself on something that had not yet happened. He was to confirm his belief in that which the Lord had not yet spoken. . . . Faith, to be faith, must center around something that is not known. Faith, to be faith, must go beyond that for which there is confirming evidence. Faith, to be faith, must go into the unknown. Faith, to be faith, must walk to the edge of the light, and then a few steps into the darkness. If everything has to be known, if everything has to be explained, if everything has to be certified, then there is no need for faith. Indeed, there is no room for it." (quoted in We Talk of Christ, by Neal A. Maxwell, p. 66)
