Do you remember when someone did a really dumb thing, saying things that if they had thought carefully, they would have said better?  Don’t judge any person by a past failure.   Remember your own failures, and misspoken words, and give that person grace.  The mark of the forgiven is that they forgive.  The mark of being in grace is giving grace.  The gracious person is maturing in grace and in the true knowledge of Jesus Christ.

“Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear.” Ephesians 4:29 (NASB)
