Latter Day Saints believe that the Holy Spirit is the sanctifier, and his sanctifying influence is called the "baptism of fire". Latter Day Saints believe that through the baptism of fire and the Holy Ghost, the heart and desires are cleansed and purified. However, confirmation is not the end but the beginning of the lifetime process of sanctification. Receiving the Holy Ghost includes inviting him into one's daily life as a "constant companion", which is believed to give strength, guidance, and enlightenment. Latter Day Saints believe that the performance of the ordinance alone is not enough to insure actual reception of the Spirit but depends on the humility, faith, and worthiness of the individual.
