From Hugh Nibley, Of All Things (1993), 14-5
When is a thing proven? When you personally think it’s so, and that’s all you can do. . .
Then you have your testimony, and all you can do is bear your testimony and point to the evidence. That’s all you can do. But you can’t impose your testimony on another. And you can’t make the other person see the evidence as you do. Things that just thrill me through and through in the Book of Mormon leave another person completely cold. And the other way around, too. So we can’t use evidence, and we can’t say, I know this is true, therefore you’d better know it is true. But I know it is true, and I pray our Heavenly Father that we may all come to a knowledge of the truth, each in his own way.
