Kind words

"Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man" (Matthew 15:11)

We have a sign in our kitchen which reads: "Speak kind words, receive kind echoes."  What would the world be like if we were all more concerned with the words that left our mouths?  

"Let us oft speak* kind words to each other at home or where ever we may be...."

*Thinking kind words is also a worthy goal.
