Holy Ghost is the Testifier of Truth

Gordon B. Hinckley

The Holy Ghost is the Testifier of Truth, who can teach men 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" (Moro. 10:4-5). ["The Father, Son, and Holy Ghost," Ensign, Mar. 1998, p. 7]

Thus the Holy Ghost is the source of saving knowledge; his mission, assigned by the Father, is to bear witness to the truth of those things which enable men to gain eternal life. His witness is sure; it cannot be controverted; it will stand forever. (A New Witness for the Articles of Faith, p.267)

2 Nephi 31

18 And then are ye in this strait and narrow path which leads to eternal life; yea, ye have entered in by the gate; ye have done according to the commandments of the Father and the Son; and ye have received the Holy Ghost, which witnesses of the Father and the Son, unto the fulfilling of the promise which he hath made, that if ye entered in by the way ye should receive.

27 As well as those who should come after, who should believe in the gifts and callings of God by the Holy Ghost, which beareth record of the Father and of the Son;

28 Which Father, Son, and Holy Ghost are one God, infinite and eternal, without end. Amen.

The Holy Ghost is the great witness of, the messenger for, and testifier of the Father and the Son. ("The Light of Christ," Ensign, May 1977, p. 44)

However, the principal mission of the Holy Ghost is to testify of our Heavenly Father and His Beloved Son, Jesus Christ. If you are careful in keeping the commandments, the Holy Ghost will help you learn more about Heavenly Father and Jesus Christ. ("Growing into the Priesthood," Ensign, Nov. 1999, pp. 40-41)

Dallin H. Oaks

If we seek and accept revelation and inspiration to enlarge our understanding of the scriptures, we will realize a fulfillment of Nephi's inspired promise that those who diligently seek will have "the mysteries of God … unfolded unto them, by the power of the Holy Ghost" (1 Ne. 10:19).

To illustrate this essential truth, consider the fact that the most important knowledge we can obtain is a testimony of the Father and the Son. This vital knowledge is received through the witness of the Holy Ghost (see D&C 20:27). ["Scripture Reading and Revelation," Ensign, Jan. 1995, p. 7]

Neal A. Maxwell

In the Holy Ghost's role in the Godhead, He "witnesses of the Father and the Son" (2 Ne. 31:18; emphasis added), and further He actually glorifies Christ (see John 16:14). Ever relevant, this glorification of our Savior is so vital in the last days, when so many esteem Jesus, the Lord of the Universe, as "naught" (1 Ne. 19:7). Therefore, at the center of the gifts of the Holy Ghost is His unique witnessing to us of Christ's atoning act, history's greatest emancipation: "To some it is given by the Holy Ghost to know that Jesus Christ is the Son of God, and that he was crucified for the sins of the world" (D&C 46:13).
