The new man is in the image of God.
Colossians 3
9 Lie not one to another, seeing that ye have put off the old man with his deeds;
10 And have put on the new man, which is renewed in knowledge after the image of him that created him:
Adam was created in the image of God Himself with a living spirit. When Adam sinned his spirit died, and when we sin we also become spiritually dead. However we who have been redeemed again bare the image of God through Christ, by our spiritual rebirth
The old man is corrupt, the new man is righteous and holy
Ephesians 4
22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
23 And be renewed in the spirit of your mind;
24 And that ye put on the new man, which after God is created in righteousness and true holiness.
As I stated earlier we who have chsen to rebel against God are in the likeness of fallen man, and have become spiritually dead, corrupting ourselves through habitually choosing sin, but when we are reborn our spirits becomes alive. Our spirits are not corrupt, but fashioned in the likeness of God, righteous in all our ways, and holy (separate from the world, and the lust thereof)
