Moroni's Promise

The last prophet within the Book of Mormon, Moroni, gave a remarkable promise [Moro. 10:3-5] to anyone that is searching for the knowledge of the truth. Over the past few years, I have had many missionaries and church members read this piece of scripture to me. It seems to be a favourite amongst the missionaries for newcomers to Mormonism. These verses read:

3 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. 4 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. 5 And by the power of the Holy Ghost ye may know the truth of all things.
