Mosiah 26:29
You always need to confess your sins to the Lord. If they
are serious transgressions, such as immorality, they need to be confessed to a
bishop or stake president. Please understand that confession is not repentance.
It is an essential step, but is not of itself adequate. Partial confession by
mentioning lesser mistakes will not help you resolve a more serious,
undisclosed transgression. Essential to forgiveness is a willingness to fully
disclose to the Lord and, where necessary, His priesthood judge all that you
have done. Remember, “He that covereth his sins shall not prosper: but whoso
confesseth and forsaketh them shall have mercy.” (“Finding Forgiveness. Richard
G. Scott April 1995)
