Rending the Veil of Unbelief -- A related quote from Elder Jeffrey R. Holland

Ether 4:14-15 has quickly become one of my favorite verses in all the scriptures:

14 Come unto me, O ye house of Israel, and it shall be made manifest unto you how great things the Father hath laid up for you, from the foundation of the world; and it hath not come unto you, because of unbelief.
15 Behold, when ye shall rend that veil of unbelief which doth cause you to remain in your awful state of wickedness, and hardness of heart, and blindness of mind, then shall the great and marvelous things which have been hid up from the foundation of the world from you—yea, when ye shall call upon the Father in my name, with a broken heart and a contrite spirit, then shall ye know that the Father hath remembered the covenant which he made unto your fathers, O house of Israel.

Elder Holland gave an address at the Sperry Symposium in 1995 on this topic, and concluded with the following words:

The Book of Mormon is predicated on the willingness of men and women to “rend that veil of unbelief” in order to behold the revelations—and the Revelation—of God (Ether 4:15). It would seem that the humbling experience of the brother of Jared in his failure to pray and his consternation over the sixteen stones were included in this account to show just how mortal and just how normal he was—so very much like the men and women we know and at least in some ways so much like ourselves. His belief in himself and his view of himself may have been limited—much like our view of ourselves. But his belief in God was unprecedented. It was without doubt or limit: “I know, O Lord, that thou hast all power, and can do whatsoever thou wilt for the benefit of man; therefore touch these stones, O Lord, with thy finger” (Ether 3:4).
And from that command given to the Lord, for it does seem to be something of a command, the brother of Jared and the reader of the Book of Mormon would never be the same again. Ordinary individuals with ordinary challenges could rend the veil of unbelief and enter the realms of eternity. And Christ, who was prepared from the foundation of the world to redeem His people, would be standing at the edge of that veil to usher the believer through. (source)
