13 Come unto me, O ye Gentiles, and I will show unto you the greater things, the knowledge which is hid up because of unbelief.
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.
Immediately after describing a vision experienced by the brother of Jared, Moroni dedicates an entire chapter to explaining the significance of this vision to us, his modern readers. Speaking on behalf of Jesus Christ, who had shown Himself to the brother of Jared and then had shown the brother of Jared “all things” (Ether 3:25-26), Moroni invites us to come unto Christ and learn “how great things the Father hath laid up for [us], from the foundation of the world.”
As part of this explanation, he informs us that God has hidden important knowledge from us because of our unbelief. This unbelief has several symptoms: wicked behavior, hardness of heart, and blindness of mind. The only way for us to receive this hidden knowledge is to intentionally “rend that veil of unbelief.”
To rend a veil sounds like something that requires effort and which may even be difficult or painful. Earlier in the Book of Mormon, we have a description of how another person was able to do that:
When Ammon taught King Lamoni, “the king believed all his words” and prayed that God would have mercy on him and on his people (Alma 18:40-41). Immediately after, he fell into a coma for two days and two nights, exactly as Ammon’s friend Alma had done after seeing an angel. (See Mosiah 27:19, 21-22.) Lamoni’s wife and servants were confused about what was happening. Some of them thought he was dead. But Ammon knew better. “He knew that king Lamoni was under the power of God; he knew that the dark veil of unbelief was being cast away from his mind” (Alma 19:6).
It’s noteworthy that King Lamoni’s experience began with his decision to believe the words of Ammon. Nevertheless, it took time for “the dark veil of unbelief” to be “cast away from his mind.” The decision to believe is the beginning of the process, but effort is required to remove the veil which covers our hearts and prevents us from believing fully. No wonder that, even after his experience of seeing an angel and being born again, Alma “fasted and prayed many days” to know these things for himself (Alma 5:46).
Today, I will choose to believe more fully. I will acknowledge the limitations of my belief and ask God to help me remove the veil of unbelief which holds me back from seeing and knowing everything He desires to share with me.
