It does not go into the mind, but into the stomach. Then it goes out of the body.” (When Jesus said this, he meant that no longer was any food unclean for people to eat.)
Good people bring good things out of the good they stored in their hearts. But evil people bring evil things out of the evil they stored in their hearts. People speak the things that are in their hearts.
“Food is for the stomach, and the stomach for food,” but God will destroy them both. The body is not for sexual sin but for the Lord, and the Lord is for the body.
And the tongue is like a fire. It is a whole world of evil among the parts of our bodies. The tongue spreads its evil through the whole body. The tongue is set on fire by hell, and it starts a fire that influences all of life.
