“And He called the multitude, and said unto them,
‘Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.’ ” Matthew 15:10-11

When Jesus said this He was addressing the hypocrisy of the religious leaders who had no heart to do His will, but their own. They knew the law but used it for their own ends and means.

Jesus was really revealing their hearts. Their hearts were vile, and evil, and with their mouths they defiled themselves. Further on in chapter 10 and in verses 16 – 20 Jesus explains His words above. All that is evil comes from the heart and is greatly expressed and exposed by the mouth.

Let us be swift to hear the word of the Lord, and in hearing it apply it to our lives beginning with the gospel of Jesus Christ and His death, burial, and resurrection; and receiving the change of heart that comes only through the new birth.

With the new birth of the Spirit we receive a new view of life and living, and an ever increasing faith in Him. With the new birth we also receive a new mouth or new vocabulary; if you will.
