Every man or woman that has ever entered into the church of God and been baptized for the remission of sins [and received the gift of the Holy Ghost] has a right to revelation, a right to the Spirit of God, to assist them in their labors. This Spirit reveals, day by day, to every man who has faith, those things which are for his benefit. The Holy Ghost will not dwell in an unholy tabernacle. If you would enjoy the full powers and gifts of your religion, you must be pure. If you are guilty of weaknesses, follies and sins, you must repent of them, that is, you must thoroughly forsake them." (D&C 59:9-12).
