Quick answer
Jesus teaches that what comes out of the mouth proceeds from the heart, and this is what defiles. It matters because it locates the source of sin within the human heart.
Overview
In contrast to food, words and the heart behind them reveal a person's true moral state. Defilement is internal and moral, not external and ceremonial. This redirects all concern about purity to the condition of the inner person. It exposes the universal human problem of a corrupt heart, which only Christ can renew.
