The Baptism of Fire and the Holy Ghost

2 Nephi 31
13 Wherefore, my beloved brethren, I know that if ye shall follow the Son, with full purpose of heart, acting no hypocrisy and no deception before God, but with real intent, repenting of your sins, witnessing unto the Father that ye are willing to take upon you the name of Christ, by baptism--yea, by following your Lord and your Savior down into the water, according to his word, behold, then shall ye receive the Holy Ghost; yea, then cometh the baptism of fire and of the Holy Ghost; and then can ye speak with the tongue of angels, and shout praises unto the Holy One of Israel. [Also see Matthew 3:11; Luke 3:16; 3 Nephi 9:20; 11:35; 12:1-2; 3 Nephi 19:13; Mormon 7:10; Ether 12:14; D&C 19:31; 20:41; 33:11; 39:6; Moses 6:66, 69]

Statements in the scriptures such as "the Holy Ghost fell on [him]" (Acts 11:15), "filled with the Holy Ghost" (Luke 1:15), "the gift of the Holy Ghost" (Acts 2:38), "receive … the Holy Ghost" (John 20:22), baptized by "fire and the Holy Ghost" (D&C 20:41) do not always refer to his person, but to his power, influence, and gifts.

The use of the word fire suggests that those who receive this gift with the right heart can expect something more than mere acceptance of certain principles or even baptism by immersion. The use of this expression elsewhere in scripture bears this out. ...

While one definition of this expression refers to a cleansing by the Holy Spirit as if by fire, still the scriptures and the writings of the prophets indicate there is something more.

The new convert who has accepted the gift of the Holy Ghost with the right spirit will experience not only a cleansing but a feeling that will give him a new heart and make of him a new person. Sometimes this is immediate, and sometimes it happens over a period of time. But always there is a change for the better. For the longer-standing member of the Church who has become preoccupied with the world or in little ways has allowed his religious life to be more procedural than of the spirit, there is something to be rediscovered (and for some, discovered for the first time) with the baptism of fire and the Holy Ghost.
