He was rich and for our sakes became poor (2 Corinthians 8:9); that is to say, he was rich in heavenly glory and power possessed by him as the great active agent of Jehovah in the creation of all things, and he became poor by becoming a man.

It was absolutely necessary for him to be a perfect man; hence he must be born holy, harmless, separate from sinners and without sin; and he met this requirement.

(Hebrews 7:26) Furthermore, he met the requirements because he was made flesh and dwelt amongst men.

(John 1:14) He partook of flesh and blood, became a human being for the very purpose of destroying him that has the power of death, that is the devil; and to deliver mankind.

(Hebrews 2:14,15) He took upon himself the form of a servant or bondsman and was made in the likeness of men.
