In today's Gospel reading from Mark 7 at morning Mass, Jesus said, "What comes out of the man, that is what defiles him. From within the man, from his heart, come evil thoughts, unchastity, theft, murder, adultery, greed, malice, deceit, licentiousness, envy, blasphemy, arrogance, folly. All these evils come from within and they defile." We can say that God deals with the heart. We are daily dealing with the heart too. For our own heart, as long as we keep it clean, we should have no fear of evil. To convert anyone, it is the heart we should aim at.
