"Death and life are in the power of the tongue, and those who love it will eat its fruit" (Proverbs 18:21)
Your words have POWER!  Weather positive or negative.  So watch what you speak.  You can build up, or tear down with your words.  You can encourage, or discourage with your words.  You can bless, or curse with your words.
YOUR WORDS HAVE POWER!
Guard my tongue Lord.
Psalm 19:14 May the words of my mouth and the meditation of my heart be pleasing in your sight, O LORD, my Rock and my Redeemer.
