When I entered high school I didn't need glasses. With each passing year, I found the chalkboards getting dustier. I had to keep moving closer, and it was annoying. At some point, after ~3 years, I complained. Someone suggested I needed glasses. One reason this had never crossed my mind was that I had eye checks as part of an annual physical that had not revealed degrading eyesight. The main reason I did not know I needed glasses was that I didn't comprehend what it would be like to not need glasses. I didn't know what perfect eyesight was like, so I couldn't realize what I was missing by wearing glasses.
Years later, I faced an alert order for deployment in the military. Knowing how hard it is to shoot accurately with glasses on, and knowing how pointless it is to try to shoot with a gas mask on when you require glasses, I thought it would be worthwhile to get laser eye surgery in spite of the cost and what I considered to be the cosmetic nature of the procedure. The procedure was very fast. The cover of my eyeball was opened, my vision got even blurrier than normal, some lights flashed, the doctor put an eye drop in my eye and put the flap back. Instantly, I saw perfectly clearly. Significantly more clearly than I ever had even with glasses. I actually cried because I was so astonished with how much better I could see. It was like being born again. I saw the world anew. Every morning I realized what it was like to be able to see right when I woke up. I had no idea how much clearer my perspective would be. I had no idea what I had been missing out on. If I did, I would have had the operation much sooner, and I would have been willing to pay a lot more than I did (at the time I think it cost me $8,000).
It is easy to preach Jesus to those who are broken and know it. It is very hard to preach Jesus to those who are already obeying that inner voice that tells them to do right. From their perspective, they can see the board fine. From their perspective, they already have their vision corrected.
Faith is to consider that there is something beyond your experience. It is to hear a description of it and believe sufficiently to experiment upon it.
26 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.
27 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.
28 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.
29 Now behold, would not this increase your faith? I say unto you, Yea; nevertheless it hath not grown up to a perfect knowledge.
30 But behold, as the seed swelleth, and sprouteth, and beginneth to grow, then you must needs say that the seed is good; for behold it swelleth, and sprouteth, and beginneth to grow. And now, behold, will not this strengthen your faith? Yea, it will strengthen your faith: for ye will say I know that this is a good seed; for behold it sprouteth and beginneth to grow.
31 And now, behold, are ye sure that this is a good seed? I say unto you, Yea; for every seed bringeth forth unto its own likeness.
32 Therefore, if a seed groweth it is good, but if it groweth not, behold it is not good, therefore it is cast away.
33 And now, behold, because ye have tried the experiment, and planted the seed, and it swelleth and sprouteth, and beginneth to grow, ye must needs know that the seed is good.
34 And now, behold, is your knowledge perfect? Yea, your knowledge is perfect in that thing, and your faith is dormant; and this because you know, for ye know that the word hath swelled your souls, and ye also know that it hath sprouted up, that your understanding doth begin to be enlightened, and your mind doth begin to expand.
35 O then, is not this real? I say unto you, Yea, because it is light; and whatsoever is light, is good, because it is discernible, therefore ye must know that it is good... (Alma 32)
The Lord said:
16 ...My doctrine is not mine, but his that sent me.Those who experiment upon his word will find it is true, and they will wonder how it is that they had never heard it/experimented upon it before. They will marvel at their improved comprehension of all that is beautiful in this world. They will be born anew.
17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. (John 7)
