I once formed a mutual encouragement fellowship at a time of stress in one of my pastorates. The members subscribed to a simple formula applied before speaking of any person or subject that was perhaps controversial. T -- is it True? H -- is it Helpful? I -- is it Inspiring? N -- is it Necessary? K -- is it Kind? If what I am about to say does not pass those tests, I will keep my mouth shut! And it worked!
