Christians hurt by ill words of others, or despairing for the falsity of a judgment rendered against them, may take the following as consolation:
Have you committed adultery? You are an adulterer still. Have you stolen? You are a thief still. So it goes. This, beyond question, is also the most harmful and effective form of slander, because it has concrete evidence from your own life to give it credibility. What to do? Return to the first point: The love that matters is the love that does not keep a record of your past wrongs as determinative of your present mind. The love that matters is the love of God, and those who love as He does.
While it is laudable and may even be necessary to correct the false judgments of others in defense of the honor of the One who lives in you, don't yield to the temptation to “set the record straight” in the minds of those who have made it clear enough they do not share your confession of the gospel. Trying to correct a false impression conveyed by someone who does not care for the truth is like trying to mend a breaching dam of manure with a band-aid. A slanderer will, if silenced in one point, always burst out with more filth on another point. It will always find a way to come out, and you will end up out of band-aids, and still covered with manure.
Rest in Christ. He will sort it out, and He will make it all right. With this, rejoice in the company of those who know all about your sins and faults, but, mindful of their own sins and thankful for their own forgiveness, don’t hold on to them and love you anyway.
