Before He came down from Heaven to make himself to become as a man?... Yes! The Lord God of Israel was a union of two different natures. He was both Soul and Deity in union.
Keep in mind. Jesus clearly stated that God is "spirit" in essence, as found in John 4:23-24.
Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and in truth, for they are the kind of worshipers the Father seeks.
God is spirit, and his worshipers must worship in the Spirit and in truth.”
Is that safe to assume that we can know that God is "spirit" in essence? Yet, the Lord God of Israel possessed two natures in union. It did not begin with the Incarnation. He always was two natures in union. Its what distinguishes the Son from the Father who is solely one nature.
Here are some proof of what I speak. See what you think...
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
God (Deity) is not soul!
As those passages reveal, the Lord Jehovah of Israel consisted of two natures in a unique union. With the same Soul that entered the body provided by Mary's womb to make Himself be as a man!
