“The Holy Ghost Testifies of Truth,” Ensign, Mar. 2010, 10–11
The Holy Ghost is the third member of the Godhead. He is a personage of spirit, without a body of flesh and bones (see D&C 130:22). He is often referred to as the Spirit, the Holy Spirit, the Spirit of God, the Spirit of the Lord, or the Comforter. He works in perfect unity with Heavenly Father and Jesus Christ.1
As a personage of spirit, the Holy Ghost can be in only one place at a time, but His influence can be everywhere at the same time.2
President Joseph Fielding Smith (1876–1972) taught, “Through the Holy Ghost the truth is woven into the very fibre and sinews of the body so that it cannot be forgotten.”3
It is also through receiving the Holy Ghost when we repent and are baptized that we may be sanctified. Sanctification is the process of becoming free from sin—pure, clean, and holy—through the Atonement of Jesus Christ (see Moses 6:59–60). We are sanctified as we yield our hearts to God (see Helaman 3:35).
The Holy Ghost testifies of truth, and it is through His power that we “may know the truth of all things” (Moroni 10:5).
The Holy Ghost teaches us all things and brings to our remembrance all we have learned of the Lord and His gospel (see John 14:26).
The Holy Ghost will “show unto [us] all things what [we] should do” (2 Nephi 32:5). He can guide us in our decisions and protect us from physical and spiritual danger.
As we hunger to know the words of eternal life and allow these words to sink deep into our hearts, the Holy Ghost will open our minds and hearts to greater light and understanding.5
The Holy Ghost is known as the Comforter because He can fill us with “hope and perfect love” (Moroni 8:26).
Adam was the first on earth to be baptized and receive the Holy Ghost (see Moses 6:64–66).
