(Galatians 4:3,4) How did God send his Son?
Since a perfect man had sinned and the life of a perfect man must be given as a sin-offering, it is now important to see if the Son of God whom he sent was qualified to meet the requirements of the law and be the ransomer or redeemer.
[212]It is easy to be seen that Jesus when on earth could not have been merely an incarnated spirit being, because that would constitute a fraud, and God would not sanction anything wrong.

He must be a man, perfect in every respect, equal and corresponding to the perfect Adam while in Eden.

It is also easy to be seen that Jesus could not be part God and part man, because that would be more than the law required; hence divine justice could not accept such as a ransom.

The divine law definitely shows that the ransomer must be exactly corresponding to Adam, a perfect human being.

How, then, did God send his Son?
And when he sent him, was he part man and part God?
[213]The Scriptures answer, as we have heretofore seen, that prior to his coming to earth he was the Logos, a spirit being; that his life was transferred to the human plane and he was born a human being.
