Honesty is a good thing, but it is not profitable to its possessor unless it is kept under control. (Don Marquis, 20th century American humorist and author)
This quote is really thought-provoking, isn’t it? Why would you have to keep honesty “under control”? Maybe the author is thinking about the harmful effects that truth may have when it is delivered uncaringly, like when you might want to be “brutally frank.” Truth is fragile and should be handled very carefully.
Speaking the truth in love (Ephesians 4:15).
