Joseph Fielding Smith
“The Spirit of God speaking to the spirit of man has power to impart truth with greater effect and understanding than the truth can be imparted by personal contact even with heavenly beings. Through the Holy Ghost the truth is woven into the very fibre and sinews of the body so that it cannot be forgotten. So positive and powerful are the teachings of the Spirit that when a man receives this knowledge and partakes of this power of God, which can only come after receiving the covenants and obligations belonging to the new and everlasting covenant, and he then turns away from this knowledge and these covenants, he sins knowingly.” 
“The nearer man approaches perfection, the clearer are his views, and the greater his enjoyments, till he has overcome the evils of his life and lost every desire for sin;” 
“There are two Comforters spoken of. One is the Holy Ghost, the same as given on the day of Pentecost, and that all Saints receive after faith, repentance, and baptism. This first Comforter or Holy Ghost has no other effect than pure intelligence. It is more powerful in expanding the mind, enlightening the understanding, and storing the intellect with present knowledge, of a man who is of the literal seed of Abraham, than one that is a Gentile, though it may not have half as much visible effect upon the body; for as the Holy Ghost falls upon one of the literal seed of Abraham, it is calm and serene; and his whole soul and body are only exercised by the pure spirit of intelligence; while the effect of the Holy Ghost upon a Gentile, is to purge out the old blood, and make him actually of the seed of Abraham. That man that has none of the blood of Abraham (naturally) must have a new creation by the Holy Ghost. In such a case, there may be more of a powerful effect upon the body, and visible to the eye, than upon an Israelite, while the Israelite at first might be far before the Gentile in pure intelligence.” 
“I will put my own definition to the term sanctification, and say it consists in overcoming every sin and bringing all into subjection to the law of Christ. God has placed in us a pure spirit; when this reigns predominant, without let or hindrance, and triumphs over the flesh and rules and governs and controls as the Lord controls the heavens and the earth, this I call the blessing of sanctification.” 
“When through the Gospel, the Spirit in man has so subdued the flesh that he can live without wilful transgression, the Spirit of God unites with his spirit, they become congenial companions, and the mind and will of the Creator is thus transmitted to the creature.” 
David O. McKay
No man can sincerely resolve to apply in his daily life the teachings of Jesus of Nazareth without sensing a change in his nature. The phrase “born again” has a deeper significance than what many people attach to it. This changed feeling may be indescribable, but it is real.
Happy the person who has truly sensed the uplifting, transforming power that comes from this nearness to the Savior, this kinship to the living Christ. I am thankful that I know that Christ is my Redeemer. 1
Spencer W. Kimball
“This is the simple total answer to the weightiest of all questions….To gain eternal life there must be a rebirth, a transformation.” 
Ezra Taft Benson
“‘Human nature can be changed, here and now,’ said President McKay, and then he quoted the following: ‘You can change human nature. No man who has felt in him the Spirit of Christ even for half a minute can deny this truth. . . . You do change human nature, your own human nature, if you surrender it to Christ. Human nature has been changed in the past. Human nature must be changed on an enormous scale in the future, unless the world is to be drowned in its own blood. And only Christ can change it.'” 
“President David O. McKay tells of a singular event that happened to him. After falling asleep, he said he ‘beheld in vision something infinitely sublime.’ He saw a beautiful city, a great concourse of people dressed in white, and the Savior.
‘The city, I understood, was his. It was the City Eternal; and the people following him were to abide there in peace and eternal happiness.
‘But who were they?
‘As if the Savior read my thoughts, he answered by pointing to a semicircle that then appeared above them, and on which were written in gold the words:
‘These Are They Who Have Overcome the World—Who Have Truly Been Born Again!
‘When I awoke, it was breaking day.’ 
When we awake and are born of God, a new day will break and Zion will be redeemed.
May we be convinced that Jesus is the Christ, choose to follow Him, be changed for Him, captained by Him, consumed in Him, and born again.” 
And this is my gospel—repentance and baptism by water, and then cometh the baptism of fire and the Holy Ghost, even the Comforter, which showeth all things, and teacheth the peaceable things of the kingdom.
And to confirm those who are baptized into the church, by the laying on of hands for the baptism of fire and the Holy Ghost, according to the scriptures;
And of tenets thou shalt not talk, but thou shalt declare repentance and faith on the Savior, and remission of sins by baptism, and by fire, yea, even the Holy Ghost.
Therefore they were called after this holy order, and were sanctified, and their garments were washed white through the blood of the Lamb. Now they, after being sanctified by the Holy Ghost, having their garments made white, being pure and spotless before God, could not look upon sin save it were with abhorrence; and there were many, exceedingly great many, who were made pure and entered into the rest of the Lord their God.
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.
3 Nephi 27:20
Now this is the commandment: Repent, all ye ends of the earth, and come unto me and be baptized in my name, that ye may be sanctified by the reception of the Holy Ghost, that ye may stand spotless before me at the last day.
And now behold, I ask of you, my brethren of the church, have ye spiritually been born of God? Have ye received his image in your countenances? Have ye experienced this mighty change in your hearts?
3 Nephi 19:13
And it came to pass when they were all baptized and had come up out of the water, the Holy Ghost did fall upon them, and they were filled with the Holy Ghost and with fire.
Mosiah 5:2, 7
And they all cried with one voice, saying: Yea, we believe all the words which thou hast spoken unto us; and also, we know of their surety and truth, because of the Spirit of the Lord Omnipotent, which has wrought a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually. And now, because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters; for behold, this day he hath spiritually begotten you; for ye say that your hearts are changed through faith on his name; therefore, ye are born of him and have become his sons and his daughters.
And the Lord said unto me: Marvel not that all mankind, yea, men and women, all nations, kindreds, tongues and people, must be born again; yea, born of God, changed from their carnal and fallen state, to a state of righteousness, being redeemed of God, becoming his sons and daughters; And thus they become new creatures; and unless they do this, they can in anowise inherit the kingdom of God.
2 Nephi 31:17
Wherefore, do the things which I have told you I have seen that your Lord and your Redeemer should do; for, for this cause have they been shown unto me, that ye might know the gate by which ye should enter. For the gate by which ye should enter is repentance and baptism by water; and then cometh a remission of your sins by fire and by the Holy Ghost.
Yea, repent and be baptized, every one of you, for a remission of your sins; yea, be baptized even by water, and then cometh the baptism of fire and of the Holy Ghost.
And it came to pass, when the Lord had spoken with Adam, our father, that Adam cried unto the Lord, and he was caught away by the Spirit of the Lord, and was carried down into the water, and was laid under the water, and was brought forth out of the water. And thus he was baptized, and the Spirit of God descended upon him, and thus he was born of the Spirit, and became quickened in the inner man. And he heard a voice out of heaven, saying: Thou art baptized with fire, and with the Holy Ghost. This is the record of the Father, and the Son, from henceforth and forever;
3 Nephi 9:20
And whoso cometh unto me with a broken heart and a contrite spirit, him will I bbaptize with fire and with the Holy Ghost, even as the Lamanites, because of their faith in me at the time of their conversion, were baptized with fire and with the Holy Ghost, and they knew it not.
3 Nephi 11:35
Verily, verily, I say unto you, that this is my doctrine, and I bear record of it from the Father; and whoso believeth in me believeth in the Father also; and unto him will the Father bear record of me, for he will visit him with fire and with the Holy Ghost.
3 Nephi 12:1
And it came to pass that when Jesus had spoken these words unto Nephi, and to those who had been called, (now the number of them who had been called, and received power and authority to baptize, was twelve) and behold, he stretched forth his hand unto the multitude, and cried unto them, saying: Blessed are ye if ye shall give heed unto the words of these twelve whom I have chosen from among you to minister unto you, and to be your servants; and unto them I have given power that they may baptize you with water; and after that ye are baptized with water, behold, I will baptize you with fire and with the Holy Ghost; therefore blessed are ye if ye shall believe in me and be baptized, after that ye have seen me and know that I am.
Bruce R. McConkie
“Baptism is in water and of the Spirit and is preceded by repentance. The actual cleansing of the soul comes when the Holy Ghost is received. The Holy Ghost is a sanctifier whose divine commission is to burn dross and evil out of a human soul as though by fire, thus giving rise to the expression baptism of fire, which is the baptism of the Spirit. Forgiveness is assured when the contrite soul receives the Holy Spirit, because the Spirit will not dwell in an unclean tabernacle.” 
“How can men become clean and pure? How can they be sanctified? What power can burn dross and evil out of a human soul as though by fire? To be saved men must be born again; they must be sanctified by the Spirit; they must receive the baptism of fire and of the Holy Ghost; they must become clean and spotless by obedience to law. The Holy Ghost is a sanctifier; no man can be saved unless he receives the gift of the Holy Ghost.” 
“It is all of the gifts of the Spirit—the miracles, signs, and wonders of the past. It is revelation and visions and a knowledge of the wonders of eternity. It is the way and the means and the power whereby the Holy Spirit of God can make of man a new creature—can burn dross and evil out of him as though by fire; can bring him forth in a newness of life, free from carnality and sin; and can sanctify his soul and make him a fit companion for Gods and angels.” 
“To be sanctified is to become clean, pure, and spotless; to be free from the blood and sins of the world; to become a new creature of the Holy Ghost, one whose body has been renewed by the rebirth of the Spirit. Sanctification is a state of saintliness, a state attained only by conformity to the laws and ordinances of the gospel. The plan of salvation is the system and means provided whereby men may sanctify their souls and thereby become worthy of a celestial inheritance.
Sanctification is a basic doctrine of the gospel Cite error: Closing missing for tag” 
Parley P. Pratt
“A man who continues in his sins, and who has no living faith in the Son of God, cannot receive the gift of the Holy Spirit through the ministration of any agent, however holy he may be. The impure spirit of such a one will repulse the pure element, upon the natural laws of sympathetic affinity, or of attraction and repulsion.
An intelligent being, in the image of God, possesses every organ, attribute, sense, sympathy, affection, of will, wisdom, love, power and gift, which is possessed by God himself. . . .
The gift of the Holy Spirit . . . quickens all the intellectual faculties, increases, enlarges, expands and purifies all the natural passions and affections; and adapts them, by the gift of wisdom, to their lawful use. It inspires, develops, cultivates and matures all the fine-toned sympathies, joys, tastes, kindred feelings and affections of our nature. It inspires virtue, kindness, goodness, tenderness, gentleness and charity. It develops beauty of person, form and features. It tends to health, vigor, animation and social feeling. It develops and invigorates all the faculties of the physical and intellectual man. It strengthens, invigorates, and gives tone to the nerves. In short, it is, as it were, marrow to the bone, joy to the heart, light to the eyes, music to the ears, and life to the whole being.
In the presence of such persons, one feels to enjoy the light of their countenances, as the genial rays of a sunbeam. Their very atmosphere diffuses a thrill, a warm glow of pure gladness and sympathy, to the heart and nerves of others who have kindred feelings, or sympathy of spirit. No matter if the parties are strangers, entirely unknown to each other in person or character; no matter if they have never spoken to each other, each will be apt to remark in his own mind, and perhaps exclaim, when referring to the interview—”O what an atmosphere encircles that stranger! How my heart thrilled with pure and holy feelings in his presence! What confidence and sympathy he inspired! his countenance and spirit gave me more assurance, than a thousand written recommendations, or introductory letters.” Such is the gift of the Holy Spirit, and such are its operations, when received through the lawful channel—the divine, eternal Priesthood.”
