“What goes into a man’s mouth does not make him ‘unclean,’ but what comes out of his mouth, that is what makes him ‘unclean.'” (Matthew 15:11)
You’ve heard the expression, you are what you eat. This verse suggests you are what you say. It’s easy to fall into the trap of thinking what we say doesn’t really matter if we mean it in jest, but the Bible repeatedly stresses the power of speech.
James compares the human tongue to a ship’s rudder and a spark that causes a blazing fire. It is no mystery that God commanded for his name not to be spoken “in vain” or without giving a thought to its meaning. Our words are so powerful that, as Paul says in the book of Romans, “if you confess with your mouth ‘Jesus is Lord,’ and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.”
Salvation requires people to verbalize their faith in Christ. The outward confession is evidence of the inward belief. As Jesus goes on to say in Matthew, “The things that come out of the mouth come from the heart.”
Try to remember that your words have power. Think about the words you want to use and what they say about your heart.
