I do not know what your concept of "human" is.
He was always being Deity and Soul in union.
He was not always walking in the weakness as in the Incarnation of limiting His abilities to become as a Man.
To become as a Man He agreed to keep the enabling abilities of His own Deity in "neutral" (Philippians 2:6-8)
for as long as it took to get him to the cross!
He remained having His Deity , but being put on hold.
That is why Satan tempted starving Jesus to turn the stones into bread.
So that Jesus would cease operating as a man. Tempting Jesus to take back up using His Deity!
If Jesus did that? He could no longer qualify to die as a man.
Not qualified to die in our place
as a man for all mankind.
The incarnation was only providing a human body for His already existing Soul.
For He was always being Deity and Soul in union! It is so declared in the Torah!
'You will eat the old supply and clear out the old because of the new.
Moreover, I will make my dwelling among you, and my soul will not
reject you.'I will also walk among you and be your God, and you shall
be My people." Lev 26:10-12
And they began to remove the foreign gods from their midst and to serve Jehovah,
so that his soul became impatient because of the trouble of Israel. Jdges 10:16
Jehovah himself examines the righteous one as well as the wicked one, and anyone
loving violence his soul certainly hates." Ps 11:5
Keep in mind.
Jesus said that God is spirit! Not soul! God is not soul! (john 4:23-24)
Consisting of a union of TWO Natures before the Incarnation was the Lord God of Israel!
You need all wheel drive for this one....
