Matthew 15:17
Do you not understand that whatever goes into the mouth passes into the stomach and afterwards into the waste?
1 Corinthians 6:13
Foods are intended for the stomach, and the stomach for foods, but God will finally put a stop to both of them. The body is not intended for sexual immorality but for the service of the Lord, and the Lord is for the body to serve.
Matthew 7:19-20
Any tree that does not bear good fruit is cut down and burned up.
Luke 6:45
The good man, out of his good inner storehouse, brings forth what is good, the bad man, out of his bad one, what is bad. For a man's mouth usually speaks the things that fill his heart.
Colossians 2:21-22
"You must not handle," "You must not taste," "You must not touch,"
James 3:6
And the tongue is a fire, and takes its place among the parts of our bodies as a world of evil; it soils the whole body and sets on fire the circle of man's nature, and itself is set on fire by hell.
