Physicians say that our tongues are about four inches long from the tip of our tongue to the back of our throat. And yet, Jesus said that our tongues are much longer than that. He said that they reach clear back beyond the throat, down into the windpipe, and into our hearts. Jesus said, “For the mouth speaks out of that which fills the heart” (Matt. 12:34). Whatever is in our hearts comes out of our lips through means of the tongue.
That’s why the Proverbs warn, “When there are many words, transgression is unavoidable” (Prov. 10:19). The more you say, the more you are bringing up from your heart. And since all of us have wicked hearts, we all will bring up something evil. So, if you are a “talker,” be warned. Your transgression will be unavoidable. There is enough muck in your heart that it will inevitably come out.
The only way to clean up your speech is to clean up your heart. Seek the Lord for a clean heart (Psalm 51:10).
