because it does not go into your heart but into your stomach and then goes on out of the body.” (In saying this, Jesus declared that all foods are fit to be eaten.)
A good person brings good out of the treasure of good things in his heart; a bad person brings bad out of his treasure of bad things. For the mouth speaks what the heart is full of.
Someone else will say, “Food is for the stomach, and the stomach is for food.” Yes; but God will put an end to both. The body is not to be used for sexual immorality, but to serve the Lord; and the Lord provides for the body.
And the tongue is like a fire. It is a world of wrong, occupying its place in our bodies and spreading evil through our whole being. It sets on fire the entire course of our existence with the fire that comes to it from hell itself.
