It is important to realize that Jesus of Nazareth was not man’s invention – no human Father’s genes, blood, or human effort produced Jesus. Though Jesus Christ had existed eternally as “the Son in the God” as “the Word of God” (John 1:1-3, 14), we will see exactly how Jesus of Nazareth was uniquely conceived of the Holy Spirit of God the Father… to be born in human form.

The “the Son of God” came to earth… to die as “the Son of Man.” Jesus of Nazareth came, shed His life’s blood, and died as… the Gift of God the Father to a lost and dying world. Now, since the cross, all those who receive God’s gift by faith, trusting in Jesus Christ unto salvation, are thereby “born of God” as their heavenly Father.

Adam and therefore mankind was and is the creation of God. We were not originally born humanly as God’s children as His offspring. But genuine grace believers who today receive Jesus Christ as God’s “Spirit-Seed” (‘seed,’ Grk, ‘sperma,’ 1Peter 1:23, Gal. 3:16) are then literally “born of God.” Thus, John wrote of genuine believers.

“who owe their [spiritual] birth neither to bloods [of man] nor to the will of the flesh [that of physical impulse] nor to the will of man [of a natural father], but to God. [THEY ARE BORN OF GOD!]” (John 1:13 (AMP)

Jesus of Nazareth’s story is not of man becoming God, but rather, God coming in human form – the ‘divine life’ putting on or being clothed with a human ‘body of flesh’… that He might die our death!

Let’s now look at the roles of the father and mother play in the conception and birth of every human born, and then look again at Jesus’ conception and birth.

We know that God as Father is the giver of the real life, the eternal spirit-life. Metaphorically, the human father is the progenitor, the giver of human life. A human father provides his seed as the spark of life to the woman’s egg. We may consider the woman’s role by the example of surrogate motherhood whereby the mother does not create life – the surrogate mother simply bears the life of a father, implanted in their womb. A mother carries the child for nine months, contributing some genetic material as to the physical flesh body; as it develops, she nourishes the unborn baby, and then gives birth to the new individual human life with a ‘body of flesh.’

It’s important that we heed this verse. “For the life of the flesh is in the blood…” (Leviticus 17:11a) The life of all flesh is “in the blood.” We also know that “God is spirit” (John 4:24) and that the life of God is the “Spirit” (Eph. 4:4). The life God gave mankind at creation is “the spirit of man” (Zech. 12:1). Since “life” is always “spirit-life” and “the life is in the blood,” this means the “spirit of a man” is In the Blood of Man. This will help us understand Jesus’ unique conception and birth, as we proceed.

It is quite surprising to most of us that the human mother’s own blood never enters the child’s blood system at any point. As we will see, mother and child do not share the same blood! The two lives of mother and child are separate and distinct because each individual’s “life of their fathers is in the blood.” The mother’s blood and the baby’s blood do not touch, they are different individual lives, persons… two different souls, having an individual life.

The fact is that Jesus’ cell ‘mitochondrial DNA’ passed to Him from the body of Mary. Because we all get our mitochondria from our mother, it can be used to track your ancestry way, way, way back through your mother's lineage by looking at what is called your “mitochondrial haplogroup.” https://www.genome.gov/genetics-glossary/Mitochondrial-DNA

Prophesying of the Messiah’s conception and construct in the womb, Jeremiah said;

Jeremiah 31:22b (NIV)…The LORD will create a new thing on earth -- a woman will surround a man.”

The word “surround” here in the NIV (above) is “compass” in the KJV, which in the Hebrew is “sabab.” This is defined by Strong’s Greek & Hebrew Dictionary as a primitive root; “to revolve, surround or border,” or encompass. The mother’s human life “surrounds” the child’s spirit-life in the womb… which is in the child’s own separate blood-life, as its individual ‘life.’

The virgin Mary was born of her father, Heli, who like all men had the “sin [nature] in the flesh” (cf. Rom. 8:3), as passed down from Adam, by whom “sin entered the world” (Rom. 5:12). Therefore, Mary received the sin-nature of her father, Heli, as all humans do. Thankfully, in the conception of Jesus of Nazareth, Mary’s human blood-life was not Jesus’ blood-life... since He was born of God The Father.  Mary then “surrounded” and nourished baby Jesus in the womb, while the Spirit-life of God was in Jesus’ Royal Blood… was separate and distinct from Mary’s blood life.

While Mary herself was conceived of her human father Heli, Jesus was conceived of the Spirit of the life of His Father God… then to be “born of a woman.”

Galatians 4:4 (NIV) …God sent HIS SON, born of a woman…

Let’s now look closer to see this matter by considering ‘fetal blood’… versus the ‘mother’s blood.’ In this you will see exactly how that the baby’s blood (with its Spirit-life) never touches the mother’s blood directly. As we will see, in His Spirit, Jesus had been… 

“born, not of blood (the blood of man), nor of the will of the (human) flesh, nor of the will of man, but of God. (John 1:13)

Read the excerpted article here below and see the ‘diagram’ mentioned in order to see how it is that, technically and medically, Mary’s human blood did not touch or taint baby Jesus’ ‘Royal Blood.’

“Fetal Blood Flow”

“A fetus (baby) is fed, or nourished, by the mother through the placenta, which is attached to the umbilical cord. In the placenta, the mother's blood and the fetal blood both flow through vessels that are very close together. But the mother's blood does NOT MIX with the fetal blood. When the mother's blood is close to the fetal blood, oxygen and nutrients move from the mother's blood into the fetal blood.

As the blood flows through the fetus, it picks up waste products and returns to the mother through the umbilical cord. The blood (with waste products from the fetus) goes through the mother's lungs and liver, where waste products are removed.

“Fetal and maternal blood circulation systems”

See chart and explanation here: https://www.trialexhibitsinc.com/library-item/maternal-fetal-circulation-illustration

The placental circulation brings two distinct circulation systems into close relationship: the maternal and the fetal. The diagram depicts the close proximity of the mother blood vessels with the blood vessels of the fetus (the baby).

“The placental barrier is composed of structures that separate the maternal and the fetal blood.”

Note that the Mother’s Blood Vessels Are Only ‘Intertwined with the Blood Vessels for The Baby’ so as to permit the walls of the blood vessels to Transfer her nutrients to the baby and the baby’s waste products back to the mother.
