Modern revelation clarifies that we are “required to forgive all men” (D&C 64:10).
President Spencer W. Kimball said: “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? … No bitterness of past frictions can be held in memory if we forgive with all our hearts” (in Conference Report, Oct. 1949, 132–33).
