9 Lie not one to another, seeing that ye have put off the old man with his deeds; 10 And have put on the new man, which is renewed in knowledge after the image of him that created him:
English Standard Version
9 Do not lie to one another, seeing that you have put off the old selfGreek man; also as supplied in verse 10 with its practices 10 and have put on the new self, which is being renewed in knowledge after the image of its creator.
9 Don't lie to one another. You're done with that old life. It's like a filthy set of ill-fitting clothes you've stripped off and put in the fire. 10 Now you're dressed in a new wardrobe. Every item of your new way of life is custom-made by the Creator, with his label on it. All the old fashions are now obsolete.
New King James Version
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,
New Living Translation
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.
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.
