The tongue is a powerful tool if used correctly, however, it can ruin relationships if miss used.   It is so easy to stick your foot in your mouth if you are not filtering the words that fly out.  The words that we speak indicate what is in our hearts.  Maybe the problem isn't our mouth, but the condition of our hearts.   Also, make sure to not stifle encouraging, uplifting and comforting words that bring life and help others. Choose your words wisely!
