5 Therefore consider the members of your earthly body as dead to immorality , impurity , passion , evil desire , and greed , which amounts to idolatry . 6 For it is because of these things that the wrath of God will come upon the sons of disobedience , 7 and in them you also once walked , when you were living in them.
8 But now you also , put them all aside : anger , wrath , malice , slander , and abusive speech from your mouth . 9 Do not lie to one another , since you laid aside the old self with its evil practices , 10 and have put on the new self who is being renewed to a true knowledge according to the image of the One 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.
