These two verses about how to know the truth of all things through the Spirit are probably the most celebrated and oft-cited verses in the Book of Mormon. What book could contain such a remarkable promise except it be of God? Countless legions have put this exhortation of Moroni to the test and have been lifted by the Spirit to a confirmation of the divinity of the work. When we ponder the scriptures and ask the Father in the name of Christ, with a sincere heart and with real intent, He will confirm the truth of His word through the Holy Ghost, who is the source for all spiritual gifts. The principle of “ask and it will be given” is a profound and eternal truth. Our faithful prayers will be answered (see James 1:5–6; Alma 5:46; 37:37; 3 Nephi 14:7; D&C 4:7). The Holy Ghost will manifest the truth of all things to us—when we ask in the name of Jesus Christ with sincerity of heart and pure intent. When we pray with faith, seeking to understand, a miracle will happen, for the Spirit will communicate to us by revelation what it is we seek to know. Said President Gordon B. Hinckley, “The Holy Ghost is the Testifier of truth, who can teach mankind things they cannot teach one another. In those great and challenging words of Moroni, a knowledge of the truth of the Book of Mormon is promised ‘by the power of the Holy Ghost.’ Moroni then declares, ‘And by the power of the Holy Ghost ye may know the truth of all things’ (Moroni 10:4–5). I believe that this power, this gift, is available to us today” (Faith: The Essence of True Religion [Salt Lake City: Deseret Book, 1989], 26).
