5 Put to death therefore what is earthly in you:[1] sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. 6 On account of these the wrath of God is coming.[2] 7 In these you too once walked, when you were living in them.
8 But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth. 9 Do not lie to one another, seeing that you have put off the old self[3] with its practices 10 and have put on the new self, which is being renewed in knowledge after the image of its creator. 11 Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave,[4] free; but Christ is all, and in all.
Matthew Henry's Commentary on Colossians 3:5-11
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.
