C. S. Lewis, 'On Forgiveness'--
"To be a Christian means to forgive the inexcusable, because God has
forgiven the inexcusable in you. This is hard. It is perhaps not so hard
to forgive a single person great injury. But to forgive the incessant
provocations of daily life--to keep on forgiving the bossy
mother-in-law, the bullying husband, the nagging wife, the selfish
daughter, the deceitful son--how can we
do it? Only, I think, by remembering where we stand, by meaning our
words when we say our prayers each night 'forgive us our trespasses as
we forgive those that trespass against us.' We are offered forgiveness
on no other terms. To refuse is to refuse God's mercy for ourselves."
Keep on forgiving do not allow resentment to build inside you, do not
dwell on the wrongs others have done to you, do not rehash hurts,
wounds, unkind words or past offences. Never forget God has forgiven the
inexcusable in you.
