And when he had entered the house and left the people, his disciples asked him about the parable. And he said to them, “Then are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile him, since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.) And he said, “What comes out of a person is what defiles him. For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. All these evil things come from within, and they defile a person.”

The Pharisees learned all the rules and were quick to recall them at the appropriate time, when they could catch someone in the act of disobedience. Unfortunately, the Pharisees were more concerned with what people were eating than whether they had food at all. The knowledge did not make it to their hearts, so what came from their mouths was cold and calculated, arrogant, and not filled with love. Have you ever had days like that? Jesus was concerned that His disciples understood that love should always rule our hearts. Only then would it overflow from their mouths. He wants this for us as well.
