(Pro 27:6 KJV) Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.
This speaks about the painful honesty of a true friend. It also reminds us of the quality of friendship that is willing to listen. I wonder what kind of friend I am. That has to do with both the speaking and the listening roles.
So? Next time you are criticized, listen and be open. The criticism may be wrong but what do you have to lose by thinking about it for a moment?
