Ephesians 4:23-24 And be renewed in the spirit of your mind; And that you put on the new man, which after God is created in righteousness and true holiness.
‘Renewed’ [Greek: ananeoo] meaning the whole course of life now flows in a different direction (2Cor. 5:17-18). Be renewed in the attitude of your mind by renouncing its vanity (4:17), its darkness and blindness (4:18) and learning of Christ (4:20-21).
From 2Corinthians 5:17-21 we were given ten personal Gospel blessings: It brings one into Christ (2Cor. 5:17). One is a new creature (2Cor. 5:17). Old things are passed away (2Cor. 5:17). The Greek word for “old” is archaios, meaning ancient, original, old. Such things are no more in one. All things are new (2Cor. 5:17). The life is just the opposite of the old life. All things are of God (2Cor. 5:18). The true Christian does not permit anything in his life which is ungodly and unChristlike (Rom. 6:14-23; 8:1-13; Gal. 5:16-26). One is reconciled to God (2Cor. 5:18; Rom. 5:10; Eph. 2:14-18; Col. 1:20-21). He has part in the ministry of reconciliation (2Cor. 5:18-20; 1:18-24). He has been trusted with the Word of reconciliation (2Cor. 5:19; Mark 16:15-20). He is an ambassador of God in Christ’s stead (2Cor. 5:20; Prov. 13:17). He is the righteousness of God in Christ (2Cor. 5:21; Rom. 3:21-31; 8:4).
‘Put on’ [Greek: enduo] to be clothed with, put on (Matt. 27:31; Mark 15:20; Luke 15:22); be clothed with (Mark 15:17; Rev. 1:13); be clothed in (Rev. 15:6; 19:14), and arrayed in (Acts 12:21). Anyone clothed with this power will be able to confirm what he lives, and this is the only normal New Testament program (John 14:12; Mark 16:16-20). The new nature must be put on and it must manifest righteousness and true holiness (4:23-24). Salvation is a hope and not actually an unforfeitable possession until the next life (1Thess. 5:8; Rom. 8:20-25; 2Thess. 2:16; 1Pet. 1:5, 9, 13). Eternal life is also a hope now, even though we possess it (Tit. 1:2; 3:7; Heb. 3:6; 6:11, 6:11, 18-19; 1Pet. 1:3, 13). It will not actually be an unforfeitable and an eternal possession until the next life and at the end of a life of sowing to the Spirit (Matt. 7:13-14; 18:8-9; 19:28-29; Mark 10:29-30; Luke 18:29-30; Rom. 2:7; 6:21-23; Gal. 6:7-8; 1Tim. 1:16; 4:8; 6:12, 19; 1Pet. 1:5, 9, 13; 3:7; 1Jn. 2:25; Jude 1:20-24; Dan. 12:2; John 5:28-29).
‘The new man, which after God is created in righteousness and true holiness.’ This is the Spirit and nature of God in renewed man (4:23-24; 2Pet. 1:4; Rom. 8:9, 14-16).
‘Holiness’ [Greek: hosiotes] A normal Christian life consists of holiness (4:24; 1Thess. 4:7; Gal. 5:19-24; Heb. 12:14).
