(10-17) In these verses we have the corresponding positive exhortation, connected with the idea of resurrection with Christ, through which we put on the new man, holding Christ to be our all in all. Of the new nature there are two marks--towards man love in all its various forms, towards God thanksgiving and living to His glory.

(10) The new man, which is (being) renewed.--There are here the same two different words which are found in the parallel passage. (See Notes on Ephesians 4:22-24). "The new man" is here properly the youthful man "which is renewed," that is, to which is given a nature really fresh and new.

Verse 10. - And having put on the new (man), which is being renewed unto (full) knowledge, after (the) image of him that created him (Ephesians 4:23, 24; Ephesians 2:15; Romans 6:4; Romans 7:6; Romans 8:1-4; Romans 13:12-14; 2 Corinthians 5:17; Galatians 6:15; Colossians 1:9; Colossians 2:2, 3; Genesis 1:26-28; Matthew 5:48; Hebrews 12:10; 1 Peter 1:16; Romans 8:29). New (νέος) is "young," "of recent date" (compare the "once," "but now" of vers. 7, 8; also Colossians 1:5-8; 1 Peter 2:1, 2). whose birth was well remembered, and which presented so vivid a contrast to the "old man with his deeds." "Being renewed" (ἀνακαινούμενον, derived from the adjective καινός) sets forth the other side of this newness, its novelty of quality and condition (compare "newness of life," Romans 6:4). And this participle is in the present tense (continuous), while the former is in the aorist (historical). So the notions are combined of a new birth taking place once for all, and a new character in course of formation. In Ephesians 4:23, 24 these ideas are in the same order (see Trench's 'Synonyms'). "Full knowledge" was one purpose of this renewal, the purpose most necessary to be set before the Colossians. The nature and objects of this knowledge have been already specified (Colossians 1:6, 9, 27, 28; Colossians 2:2, 3, 9, 10: comp. Ephesians 1:18, 19; Ephesians 3:18, 19; Philippians 3:8-14; 1 Corinthians 1:18-31; and on ἐπίγνωσις, see note, Colossians 1:6). "After (the) image" is clearly an allusion to Genesis 1:26-28; so in Ephesians 4:24 ("after God"). It is adverbial to "renewed," not to "knowledge." Man's renewal in Christ makes him what the Creator at first designed him to be, namely, his own image (compare note on "reconcile," Colossians 1:20). Chrysostom and others take "Christ" as "him that created," in view of Colossians 1:15, 16; but then it is said that all things "were created in... through... for Christ," not absolutely that Christ created them. But "the image of God after which" man was created and is now recreated, is seen in Christ (Romans 8:29; 2 Corinthians 3:18; 2 Corinthians 4:4; John 1:18).

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.And have put on the new man,.... Concerning which, and the putting it on; see Gill on Ephesians 4:24,

which is renewed in knowledge; this man, or principle of grace in the soul, is a new one, which never was there before; and there is a daily renovation of it in the spirit of the mind, by the Spirit of God; for as the outward man decays, the inward man, which is the same with this new man, is renewed day by day, increases in holiness and righteousness, grows in grace, and particularly in "knowledge"; light and knowledge of a man's self, of his lost state and condition by nature, of his need of Christ, and of his salvation, is what appears at the first formation of this new man; and the daily renovation of him lies in an increase of spiritual, experimental, and saving knowledge of God, and Christ, and divine things; and indeed, until a man becomes a new creature, he neither knows, nor is he capable of knowing, the things of the Spirit of God; so that this new man, or principle of grace, begins with spiritual knowledge, and is formed in order to it, and its increase lies in it:

after the image of him that created him; the new man; for this is a creation work, and so not man's, but God's; and is made not after the image of the first man, no not as innocent, and much less as fallen; but after the image of Christ, to which the elect of God are predestinated to he conformed, and which is stamped in regeneration; and more and more appears by every transforming view of Christ, and will be perfected in heaven, when they shall see him as he is, and be perfectly like him, who is not only the pattern, but the Creator of it, even the author and finisher of faith.
