Colossians 3:9

As we are to mortify inordinate appetites, so we are to mortify inordinate passions (Col 3:8): But now you also put off all these, anger wrath, malice; for these are contrary to the design of the gospel, as well as grosser impurities; and, though they are more spiritual wickedness, have not less malignity in them. The gospel religion introduces a change of the higher as well as the lower powers of the soul, and supports the dominion of right reason and conscience over appetite and passion. Anger and wrath are bad, but malice is worse, because it is more rooted and deliberate; it is anger heightened and settled. And, as the corrupt principles in the heart must be cut off, so the product of them in the tongue; as blasphemy, which seems there to mean, not so much speaking ill of God as speaking ill of men, giving ill language to them, or raising ill reports of them, and injuring their good name by any evil arts, - filthy communication, that is, all lewd and wanton discourse, which comes from a polluted mind in the speaker and propagates the same defilements in the hearers, - and lying: Lie not one to another (Col 3:9), for it is contrary both to the law of truth and the law of love, it is both unjust and unkind, and naturally tends to destroy all faith and friendship among mankind. Lying makes us like the devil (who is the father of lies), and is a prime part of the devil's image upon our souls; and therefore we are cautioned against this sin by this general reason: Seeing you have put off the old man with his deeds, and have put on the new man, Col 3:10. The consideration that we have by profession put away sin and espoused the cause and interest of Christ, that we have renounced all sin and stand engaged to Christ, should fortify us against this sin of lying. Those who have put off the old man have put it off with its deeds; and those who have put on the new man must put on all its deeds - not only espouse good principles but act them in a good conversation. The new man is said to be renewed in knowledge, because an ignorant soul cannot be a good soul. Without knowledge the heart cannot be good, Pro 19:2. The grace of God works upon the will and affections by renewing the understanding. Light is the first thing in the new creation, as it was in the first: after the image of him who created him. It was the honour of man in innocence that he was made after the image of God; but that image was defaced and lost by sin, and is renewed by sanctifying grace: so that a renewed soul is something like what Adam was in the day he was created. In the privilege and duty of sanctification there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free, Col 3:11. There is now no difference arising from different country or different condition and circumstance of life: it is as much the duty of the one as of the other to be holy, and as much the privilege of the one as of the other to receive from God the grace to be so. Christ came to take down all partition-walls, that all might stand on the same level before God, both in duty and privilege. And for this reason, because Christ is all in all. Christ is a Christian's all, his only Lord and Saviour, and all his hope and happiness. And to those who are sanctified, one as well as another and whatever they are in other respects, he is all in all, the Alpha and Omega, the beginning and the end: he is all in all things to them.
