The Eternal Son of God made man in His own image. In the Son "was life; and the life was the light of men" (John 1:4). But the image was lost. The same Eternal Son took this nature, in the likeness of sinful flesh yet without sin (and therefore without the image lost) into union with His own divine person. He did so in order that the image might be restored in those united to Himself as His own people.
The image maker united the image bearing nature with His person in order to restore the image in those that had sinned but are united to Him by faith.
