Episode 017 The Book of Ether: "The Trial of Faith"
“Now, as I said concerning faith—that it was not a perfect knowledge—even so it is with my words. Ye cannot know of their surety at first, unto perfection, any more than faith is a perfect knowledge.
But behold, if ye will awake and arouse your faculties, even to an experiment upon my words, and exercise a particle of faith, yea, even if ye can no more than desire to believe, let this desire work in you, even until ye believe in a manner that ye can give place for a portion of my words.
Now, we will compare the word unto a seed. Now, if ye give place, that a seed may be planted in your heart, behold, if it be a true seed, or a good seed, if ye do not cast it out by your unbelief, that ye will resist the Spirit of the Lord, behold, it will begin to swell within your breasts; and when you feel these swelling motions, ye will begin to say within yourselves—It must needs be that this is a good seed, or that the word is good, for it beginneth to enlarge my soul; yea, it beginneth to enlighten my understanding, yea, it beginneth to be delicious to me.”
Alma 32:26-28
And now, I, Moroni, would speak somewhat concerning these things; I would show unto the world that faith is things which are hoped for and not seen; wherefore, dispute not because ye see not, for ye receive no witness until after the trial of your faith.
For it was by faith that Christ showed himself unto our fathers, after he had risen from the dead; and he showed not himself unto them until after they had faith in him; wherefore, it must needs be that some had faith in him, for he showed himself not unto the world.
But because of the faith of men he has shown himself unto the world, and glorified the name of the Father, and prepared a way that thereby others might be partakers of the heavenly gift, that they might hope for those things which they have not seen.
Wherefore, ye may also have hope, and be partakers of the gift, if ye will but have faith.
Behold it was by faith that they of old were called after the holy order of God.
Wherefore, by faith was the law of Moses given. But in the gift of his Son hath God prepared a more excellent way; and it is by faith that it hath been fulfilled.
For if there be no faith among the children of men God can do no miracle among them; wherefore, he showed not himself until after their faith…”
Ether 12:6-12
