Colossians 3:10 And have put on the new man, which is renewed in knowledge after the image of him that created him
‘Put on the new man.’ Nine things to put on (3:10, 12): The new man (Eph. 4:24); bowels of mercies (2Cor. 6:12); kindness (1Cor. 13:4); humbleness of mind; meekness (1Cor. 13:4); longsuffering (1Cor. 13:4); forbearance (Gal. 5:22); forgiveness (Matt. 18:35); divine love (1Cor. 13:4).
‘New man’ – This is the Spirit and nature of God in renewed man (Eph. 4:23-24; 2Pet. 1:4; Rom. 8:9, 14-16).
‘Renewed in knowledge’ – Therefore, because we do not know any man after the flesh, not even Christ, it is vain for any man to profess a relationship with Christ according to the flesh, while he is unchanged in heart and life and dead in trespasses and sins. One must be renewed in the attitude of your mind by renouncing its vanity (Eph. 4:17), its darkness and blindness (Eph. 4:18) and learning of Christ (Eph. 4:20-21).
‘Knowledge’ [Greek: epignosis] full and true knowledge (3:10; 1:9-10; Rom. 1:28; 3:20; 10:2; Eph. 1:17; 4:13; Php. 1:9; 1Tim. 2:4; 2Tim. 3:7; Heb. 10:26; 2Pet. 1:2, 3, 8; 2:20) and acknowledge (2:2; 2Tim. 2:25; Tit. 1:1; Phm. 1:6). Ignorance is the state of the average heathen who gets to know only a little about nature. Christianity teaches man the true and full knowledge of God and nature, and the origin and destiny of all things (Acts 15:18; Eph. 2:7; 3:9-11).
‘Image’ [Greek: eikon] This is one of three places where the word means a pattern or moral and spiritual likeness (3:10; Rom. 8:29; 2Cor. 3:18). The idea here is that God planned for man to have full knowledge. Now He renews man after the original pattern or plan and gives him a sound mind and true knowledge (2Tim. 1:7; 2Pet. 1:3-13). This could read, “renewed in knowledge according to the original pattern of God who created him.”
