The Need for Temple Worthiness
Doctrine and Covenants 109:20–21
20 And that no unclean thing shall be permitted to come into thy house to pollute it;
21 And when thy people transgress, any of them, they may speedily repent and return unto thee, and find favor in thy sight, and be restored to the blessings which thou hast ordained to be poured out upon those who shall reverence thee in thy house.
President Spencer W. Kimball said:
“Holy temples may . . . be defiled and desecrated by members of the Church who go into the temple and make covenants unworthily or which they are not prepared or willing to accept and carry forward. When people go to the temple and then make light of its sacred principles, they are defiling it. When unrepentant people accept the holy ordinances without full determination to prove worthy of them, they are helping to violate the sacredness of the holy temple and they are desecrating holy places.”
