Mark 7:17-23 English Standard Version

17 And when he had entered the house and left the people, his disciples asked him about the parable. 18 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, 19 since it enters not his heart but his stomach, and is expelled?”[a] 20 And he said, “What comes out of a person is what defiles him. 21 For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, 22 coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. 23 All these evil things come from within, and they defile a person.”

Focus on what goes into the heart.
