5 Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. 6 Because of these things the wrath of God is coming upon the sons of disobedience, 7 in which you yourselves once walked when you lived in them.
8 But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. 9 Do not lie to one another, since you have put off the old man with his deeds, 10 and have put on the new man who is renewed in knowledge according to the image of Him who created him,
Matthew Henry's Commentary on Colossians 3:5-10
Commentary on Colossians 3:5-11
(Read Colossians 3:5-11)
It is our duty to mortify our members which incline to the things of the world. Mortify them, kill them, suppress them, as weeds or vermin which spread and destroy all about them. Continual opposition must be made to all corrupt workings, and no provision made for carnal indulgences. Occasions of sin must be avoided: the lusts of the flesh, and the love of the world; and covetousness, which is idolatry; love of present good, and of outward enjoyments. It is necessary to mortify sins, because if we do not kill them, they will kill us. The gospel changes the higher as well as the lower powers of the soul, and supports the rule of right reason and conscience, over appetite and passion. There is now no difference from country, or conditions and circumstances of life. It is the duty of every one to be holy, because Christ is a Christian's All, his only Lord and Saviour, and all his hope and happiness.
