Ephesians 4:24

And that ye put on the new man, which after God is created in righteousness and true holiness.

Put on the new man - opposed to "the old man," which is to be "put off" (Ephesians 4:22) [ kainon (G2537) is different from "re-newed," Ephesians 4:23 ]. Put on not merely a renovated nature, but the new - i:e., altogether different, changed-nature, which redemption contemplates (Colossians 3:9; Colossians 3:12, note).

After God ... Translate, 'which hath been created (once for all [ ktisthenta (G2936)] in Christ, Ephesians 2:10; so that in each believer this new holy garment has not to be created again, but to be put on) after (the image of) God,' (Genesis 1:27; 1 Peter 1:15, etc.) God's image, which we lost in the first Adam, is restored to us more gloriously in the second Adam, the image of the invisible God (2 Corinthians 4:4; Colossians 1:15; Hebrews 1:3).

In righteousness - "IN" it as the element of the renewed man: opposed to "greediness," which covetously disregards right (Ephesians 4:19).

True holiness - opposed to "uncleanness:" Greek, 'piety [ hosiotes (G3742)] of the truth;' flowing from following "the truth of God" (Romans 1:25; Romans 3:7; Romans 15:8): opposed to 'the lusts of deceit' (Greek, Ephesians 4:22: cf. also Ephesians 4:21, "truth in Jesus"). "Righteousness" relates to our fellowmen, the second table; "holiness" to God, the first table: the religious observance of offices of piety (cf. Luke 1:75). In the parallel (Colossians 3:10) it is "renewed in knowledge after the image," etc. As at Colosse the danger was from pretenders to knowledge, the true "knowledge" which flows from renewal of the heart is dwelt on; so at Ephesus, the danger being from the corrupt morals prevalent, the renewal in "holiness," "righteousness," contrasted with Gentile "uncleanness" (Ephesians 4:19), and "greediness," is prominent.
