Mary can only be a mother to a normal human being, Mary can’t be pregnant and give birth to a spirit because a spirit doesn’t have a body.
Mary can’t be a surrogate mother of God because a “Surrogate” mother bears a child on behalf of another woman. God is masculine and feminine and there is no God the mother in heaven for Mary to be a surrogate mother on behalf of. Mothers, sons, and daughters are terms that only apply to humans that God creates.
You keep avoiding that no human flesh, bone, and blood is Deity (simply a house or tabernacle for the Spirit of God to abide in). God put His Spirit in the Temple of Solomon (in the Holy of Holies). But God later decides to put His Spirit inside a human and become just like us in our humanity.
God didn’t choose Mary because she was a virgin. Since our Bible says that “All have sinned and come short of God’s Glory”, “There is none righteous, no not one” (including Mary and Joseph, and you and me.
It was the faith of Joseph, Mary and their families that pleased God. The parents of Jesus had the same faith as Abraham, Isaac, Jacob, and King David, and a silly need for a virgin birth is ludicrous and “So foolish, unreasonable, or out of place as to be amusing; ridiculous”.
God put His own Spirit in the body of Jesus at the child’s conception. We, humans, sin because we are “Created beings” and we are not GOD’s or a God. Christians say that their bodies are a Temple for God’s Spirit to dwell in (and when we sin we don’t cause God to be tarnished by our sins).
Mary’s other children (4 brothers and at least 2 sisters) were also conceived “Normally” but they instead received human created spirits at their conception, making them mortal and sinful just like you and me.
Jesus can’t sin in his actions and words simply because the Spirit of God is residing in his body and sin always starts in the mind and spirit of an individual. If I go and kill someone with a gun, Jesus would say that I have already killed him or her in my heart (long before I used the gun.
Which means that all sins originate in the spirit of a person. Since Jesus has no human spirit in his body but only “The Holy of Holies” residing in his being, then God is perfectly able to keep the human body of Jesus from sinning. To think otherwise just means that someone’s God is very weak and impotent (“Unable to take effective action; helpless or powerless” to stay perfect in a sinful world).
Barry, try to think of Jesus as the “House” of God, and the Spirit of God that lives in that house is kept clean by the Spirit of the Living God who gives Jesus the desire and strength to resist “All” sins that a human body will desire to engage in.
The Bible says about God “I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty” refers to God. God has no past or future, he is a present tense kind of God.
God became a son when God put His Spirit inside the child of Joseph and Mary. Jesus is not a son until his conception (just like all humans don’t exist until their conception in their mother’s womb.
When a pagan saw 2 Apostles doing miracles he said, “Behold, the gods have come down to us”. If I were to interview that man and ask, do you believe these men are human beings? And he would say, “Yes these are men born of a virgin who pre-exist their conception in their mother’s womb.
“Coming down to us” means they exist before their conception. That is why the pagans who became Catholics added that pre-existence of Jesus to make Jesus equal to the God’s that the pagans already believe in; otherwise, the pagans would perceive that their God’s are superior to the Christian God.
A Jewish person seeing Jesus and the Apostles heal someone would say, “They marveled and glorified God, who had given such power to men”. Notice that they didn’t perceive any humans as being God’s “coming down to them. But the Jews were unaware that the “Strictly human” Jesus is now the dwelling place (abode) of God’s Spirit. If Christians would teach that Jesus is an instrument or vessel that God used and stopped wanting to Deify his humanness, the Jews would accept Jesus as their “Real” Jewish Messiah, the son of Joseph and Mary who is human “Like” us.
When Jesus said before Abraham was I am, he was referring to God because the body of Jesus didn’t exist in heaven or in Abraham’s time. And God can’t be a son before he is a son, because there is only “One” God.
Here o Israel, the Lord our God is one Lord. Jesus is praying to God, which means he isn’t praying to himself. The humanity of Jesus is crying out to the one God because he is experiencing the pain that all other human’s anguish over.
