14 He called all the multitude to himself, and said to them, “Hear me, all of you, and understand. 15 There is nothing from outside of the man, that going into him can defile him; but the things which proceed out of the man are those that defile the man. 16 If anyone has ears to hear, let him hear!”
Matthew Henry's Commentary on Mark 7:14-16
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.
