And have put on the new man, {8} which is renewed in {e} knowledge after the image of him that created him:

(8) Newness of life consists in knowledge which transforms man to the image of God his maker, that is to say to the sincerity and pureness of the whole soul.

(e) He speaks of an effectual knowledge.

People's New Testament

3:10 Have put on the new man. Are born again and become new creatures in Christ (Joh 3:5). The new man has a new heart, new thoughts, a new life.

Which is renewed in knowledge. With the new man there is a growth, a renewal. He grows continually in knowledge of Christ and into his image.

Wesley's Notes

3:10 In knowledge - The knowledge of God, his will, his word.

10. the new man-(See on [2425]Eph 4:23). Here (neon) the Greek, means "the recently-put-on nature"; that lately received at regeneration (see on [2426]Eph 4:23, 24).

which is renewed-Greek, "which is being renewed" (anakainottmenou); namely, its development into a perfectly renewed nature is continually progressing to completion.

in knowledge-rather as the Greek, "unto perfect knowledge" (see on [2427]Col 1:6; [2428]Col 1:9, 10). Perfect knowledge of God excludes all sin (Joh 17:3).

after the image of him that created him-namely, of God that created the new man (Eph 2:10; 4:24). The new creation is analogous to the first creation (2Co 4:6). As man was then made in the image of God naturally, so now spiritually. But the image of God formed in us by the Spirit of God, is as much more glorious than that borne by Adam, as the Second Man, the Lord from heaven, is more glorious than the first man. Ge 1:26, "Let us make man in our image, after our likeness." The "image" is claimed for man, 1Co 11:7; the "likeness," Jas 3:9. Origen [On First Principles, 3:6] taught, the image was something in which all were created, and which continued to man after the fall (Ge 9:6). The likeness was something towards which man was created, that he might strive after it and attain it. Trench thinks God in the double statement (Ge 1:26), contemplates both man's first creation and his being "renewed in knowledge after the image of Him that created Him."

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Verses 8-11

As we are to mortify inordinate appetites, so we are to mortify inordinate passions (v. 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 (v. 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, v. 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, Prov. 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, v. 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.
