“Remember that we must forgive even if our offender did not repent and ask forgiveness … Do we follow that commandment or do we sulk in our bitterness, waiting for our offender to learn of it and to kneel to us in remorse? … this reconciliation suggests also forgetting. Unless you forget, have you forgiven?… No bitterness of past frictions can be held in memory if we forgive with all our hearts.” (Spencer W. Kimball, Conference Report, Oct. 1949, pp. 132-133 )
