5 So put to death the sinful, earthly things lurking within you. Have nothing to do with sexual immorality, impurity, lust, and evil desires. Don't be greedy, for a greedy person is an idolater, worshiping the things of this world. 6 Because of these sins, the anger of God is coming. 7 You used to do these things when your life was still part of this world.
8 But now is the time to get rid of anger, rage, malicious behavior, slander, and dirty language. 9 Don't lie to each other, for you have stripped off your old sinful nature and all its wicked deeds. 10 Put on your new nature, and be renewed as you learn to know your Creator and become like 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.
