Holy Ghost is a Cleansing and Purifying Agent

Man can only become spotless and sanctified by the reception of the Holy Ghost in his personal life. The Holy Ghost is a cleansing and purifying agent to all who receive it and are righteous. This means that sin and iniquity are spiritually burned out of the repentant person. He then receives a remission of sins, and his soul is sanctified and made clean for the Holy Ghost to abide in him. (Delbert L Stapley, Conference Report, October 1966, p.112)
