He did it as a Man. He had to do it as a Man to save us and reverse what Adam had done.
amen he God became a man fully and accomplished everything restored of a man to live and not die and then he returned to his glory of the heavens
Mans place is inherant from creation that we are fully subject to Gods rule yet we have the dominion as stewards meant to rule in the ways of God over all the earth
Jesus the lord saw from heaven that we were lost because there was no man To intercede on our behalf no sinless man to approach God and stone for our sins by mediation ( there was no perfect priest )
When the lord saw this it displeased him and so he announced that he would come and become the perfect man to intercede and save us
“Yea,
truth faileth; and he that departeth from evil maketh himself a prey: and
the LORD saw it, and it displeased him that there was no judgment. And he saw that there was no man, and wondered that there was no intercessor:
therefore
his arm brought salvation unto him; and
his righteousness, it sustained
him. For
he put on righteousness as a breastplate, and
an helmet of salvation upon his head; and
he put on the garments of vengeance for
clothing, and was clad with zeal as a cloke.
…So shall they
fear the name of the LORD from the west, and his glory from the rising of the sun. When the enemy shall come in like a flood,
the Spirit of the LORD shall lift up a standard against him.
And
the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD.
As for me, this is my covenant with them, saith
the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed,
saith the LORD, from henceforth and for ever.”
Isaiah 59:15-17, 19-21
After Jesus accomplished the life of a perfect man making his own self subject being fully the form of a man on earth he was glorofied as in the beginning
“
I have glorified thee on the earth: I have
finished the work which thou gavest me to do.
And now, O
Father, glorify thou me with thine own self with the glory which I had with thee before the world was.”
John 17:4-5 KJV
while jesus was on earth before he rose from the dead and apart from the transfiguration , he was fully in the form of one of us “ the son of God “ in full and total subjection was Jesus humanity to the spirit of God within him
after he was glorified returning to the glory of the most high having revealed himself to humanity once for all by the gospel but now he has created an intercessor that can save us being worthy when there was no man before now there is an intercessor and advocate
“Who is he that condemneth? It is
Christ that died, yea rather, that is risen again, who
is even at the right hand of God, who also maketh intercession for us.”
Romans 8:34 KJV
We couldnt be saved without this part still
“My little children, these things write I unto you, that ye sin not. And
if any man sin, we have an advocate with the Father, Jesus Christ the righteous:”
1 John 2:1 KJV
when he looked down and saw there was no man no intercessor he came and became the perfect man we needed able to intercede and mediate relationship for all Men who are simply imperfect
“For there is
one God, and one mediator between God and men, the man Christ Jesus; who gave himself a ransom for all, to be testified in due time.”
1 Timothy 2:5-6 KJV
This is not two seperate people but God of heaven who
became a man in order to save mankind from sin and death interceding between God and man to reconcile man and gods broken relationship through adams rule
