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.For from within, out of the heart of man,.... The inside of man is very bad, his inward part is not only wicked, but wickedness itself, yea, very wickedness, Psalm 5:9, in him dwells no good thing naturally, his heart is wicked, and desperately so; it is full of evil; and out of the abundance of it, proceed the evil things hereafter mentioned; all its powers and faculties are vitiated, there is no place clean; the understanding and judgment are dreadfully corrupted; the mind and conscience are defiled; the affections are inordinate; not only the thought, but every imagination of the thought of the heart is evil, and that continually: what good thing therefore, can come out of such a Nazareth as this? Nothing, but what follows: for from hence

proceed evil thoughts, adulteries, fornications, murders; which several things are related in Mat_. 15:19 see the note on Matthew 15:19; only the order here is a little different; "murders", which are here mentioned last, are there put after "evil thoughts".
