“Wrought Upon and Cleansed by the Power of the Holy Ghost”

"That which is wrought upon is changed in some basic or essential way, usually by means of hand tools through twisting, beating, or embellishing. In this sense used here it is symbolic and has reference to what occurs when the Spirit quickens and changes the convert to a new creature. But an important insight is that it is through the cleansing power of the Holy Ghost that one's sins are actually purged, or removed. It is the atoning sacrifice of Christ that makes the remission of our sins possible, but the actual cleansing influence is the baptism of fire, or of the Holy Ghost." (Book of Mormon Student Manual, 1981, p. 509)
