Elder Orson Pratt explained concerning the powers of the Holy Ghost: “Water baptism is only a preparatory cleansing of the believing penitent... whereas, the baptism of fire and the Holy Ghost cleanses more thoroughly, by renewing the inner man, and by purifying the affections, desires, and thoughts which have long been habituated in the impure ways if sin.
Without the aid of the Holy Ghost, a person would have but very little power to change his mind, at once, from its habituated course, and to walk in newness of life... So great is the force of habit, that he would, without being renewed by the Holy Ghost, be easily overcome, and contaminated again with sin. Hence, it is infinitely important that the affections and desires should be, in a measure, changed and renewed, so as to cause him to hate that which he before loved, and to love that which he before hated. To thus renew the mind of man is the work of the Holy Ghost.” (The Holy Spirit, “ pp. 56-57.)”
