IOW Jesus Crist, The God-Man.
Even before the Incarnation as the Lord God of Israel He consisted of two natures in union. The Incarnation simply provided a body for His Soul to inhabit as a man!
Here are some OT passages that state the Lord God of Israel was manifested as both Deity and Soul in union.
'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
“Bring no more futile sacrifices; Incense is an abomination to Me.
The New Moons, the Sabbaths, and the calling of assemblies—
I cannot endure iniquity and the sacred meeting. Your New Moons
and your appointed feasts My soul hates; They are a trouble to Me,
I am weary of bearing them.. Isa 1:13-14
What Jesus was being was the eternal Soul of the Lord God of Israel being manifested in a sinless human body, manifested as a PERFECT man!
Keep in mind!
Jesus said that God is
'spirit.' God's
'spirit' essence is not soul!
The Lord God of Israel consisted as a union of Soul and Deity! No body!
But the hour is coming, and now is, when the true worshipers will worship
the Father in spirit and truth; for the Father is seeking such to worship Him.
God is spirit, and those who worship Him must worship in spirit and truth.” John 4:23-24
That is a mystery solved.
