This is one of my favorite verses and one I want to apply to my life every time I read it. And in a world of sarcasm and come backs, I think these words would still make people take notice.
"And all spoke well of him and marveled at the gracious words that were coming from his mouth. And they said, “Is not this Joseph’s son?” ~Luke 4:22
Praying that "gracious words" would be the only kind that come out of my mouth.
