Do you cherish any resentment or hatred towards another, to whom you refuse to be reconciled?
…
Is there some injustice which you refuse to forgive, some charge which you refuse to pay, some wrong which you refuse to confess?
Are you allowing something yourself which you would be the first to condemn in others, but which you argue may be permitted in your own case, because of certain reasons with which you attempt to smother the remonstrances of conscience?
