20 And he said, "It is what comes out of a person that defiles. 21 For it is from within, from the human heart, that evil intentions come: fornication, theft, murder, 22 adultery, avarice, wickedness, deceit, licentiousness, envy, slander, pride, folly. 23 All these evil things come from within, and they defile a person."
Matthew Henry's Commentary on Mark 7:20-23
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.
