Aaron, a Nephite missionary to the Lamanites, was teaching the Lamanite king. As they begin their discussion in Alma 22, the King lets Aaron know he is willing to believe the things Aaron says concerning the nature and will of God. After Aaron teaches the Gospel to the King, the King states that he would forsake even his kingdom if he will be saved by God through Jesus. Aaron tells the King, “If thou desirest this thing, if thou wilt bow down before God, yea, if thou wilt repent of all thy sins, and will bow down before God, and call on his name in faith, believing that ye shall receive, then shalt thou receive the hope which thou desirest. (Alma 22:16)”
Immediately the King responds in kind:
And it came to pass that when Aaron had said these words, the king did bow down before the Lord, upon his knees; yea, even he did prostrate himself upon the earth, and cried mightily, saying:
O God, Aaron hath told me that there is a God; and if there is a God, and if thou art God, wilt thou make thyself known unto me, and I will give away all my sins to know thee, and that I may be raised from the dead, and be saved at the last day. And now when the king had said these words, he was struck as if he were dead.
Alma 22:17-18
The course of action taken by the King is described by the prophet Alma while talking to a group of poor and disenfranchised individuals in Alma 32:27. “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.” Gaining and strengthening our faith in God and His Gospel is made possible by experimenting on His teachings. If there is ever a question as to the veracity, even if you have just a particle of faith or the barest desire to believe, exercise that desire to experiment on the words of Christ and learn the truth.
One of the last promises made in the Book of Mormon describes how we can perform an experiment like the one Alma talks about here:
Behold, I would exhort you that when ye shall read these things, if it be wisdom in God that ye should read them, that ye would remember how merciful the Lord hath been unto the children of men, from the creation of Adam even down until the time that ye shall receive these things, and ponder it in your hearts.
And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost.
And by the power of the Holy Ghost ye may know the truth of all things.
Moroni 10:3-5
The King, without realizing it, followed both Alma’s and Moroni’s advice to experiment on the words and ask God.
