14 Then Jesus called to the crowd to come and hear. "All of you listen," he said, "and try to understand. 15 It's not what goes into your body that defiles you; you are defiled by what comes from your heart. " 16 17 Then Jesus went into a house to get away from the crowd, and his disciples asked him what he meant by the parable he had just used. 18 "Don't you understand either?" he asked. "Can't you see that the food you put into your body cannot defile you? 19 Food doesn't go into your heart, but only passes through the stomach and then goes into the sewer." (By saying this, he declared that every kind of food is acceptable in God's eyes.) 20 And then he added, "It is what comes from inside that defiles you. 21 For from within, out of a person's heart, come evil thoughts, sexual immorality, theft, murder, 22 adultery, greed, wickedness, deceit, lustful desires, envy, slander, pride, and foolishness. 23 All these vile things come from within; they are what defile you."

Commentary on Mark 7:14-23
(Read Mark 7:14-23)
Our wicked thoughts and affections, words and actions, defile us, and these only. As a corrupt fountain sends forth corrupt streams, so does a corrupt heart send forth corrupt reasonings, corrupt appetites and passions, and all the wicked words and actions that come from them. A spiritual understanding of the law of God, and a sense of the evil of sin, will cause a man to seek for the grace of the Holy Spirit, to keep down the evil thoughts and affections that work within.
