Elder Joseph Whirlwith gives a Great Analysis of Moroni 10:3-5

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.

Do you wish to break the barriers that separate mortals from the knowledge of eternal verities? Do you wish to know—really know—the truth? Then follow Moroni’s counsel and you will surely find what you seek. “Be sincere. Study. Ponder. Pray sincerely, having faith. “If you do these things, you too will be able to stand with the millions who testify that God once again speaks to man on earth.” —Elder Joseph B. Wirthlin of the Quorum of the Twelve Apostles, “Pure Testimony,” Ensign, Nov. 2000, 23.
