5 Put to death therefore your members which are upon the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry; 6 for which things' sake cometh the wrath of God upon the sons of disobedience: 7 wherein ye also once walked, when ye lived in these things;
8 but now do ye also put them all away: anger, wrath, malice, railing, shameful speaking out of your mouth: 9 lie not one to another; seeing that ye have put off the old man with his doings, 10 and have put on the new man, that is being renewed unto knowledge after the image of him that created him:

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.
