The dual Gospel genealogies raise an intellectually-challenging question: how could a sinful woman conceive and carry a sinless child? And Mary admitted to being a sinner. In her song, Luke 1:46-47, she exulted, “My soul glorifies the Lord and my spirit rejoices in God my Savior.”
“My Savior” means she needed forgiveness of sin. Do not let the adoration of later ages ascribe to Mary what she never claimed, wanted or possessed. Trust God’s unchanging Word, not an always-evolving church tradition, to tell the truth. Indeed, every person ever to live, who reaches the age of accountability, needs a Savior. And Jesus alone, all by himself, IS the Savior all humanity needs.
The question is valid; the answer equally valid. Consider that it’s as uncomplicated as the Holy Spirit coming upon her and the power of the Most High overshadowing her...“So the holy one to be born will be called the Son of God” Luke 1:35. In a wholly spiritual process, God’s wholly spiritual power, minus sexual passion, produced a wholly spiritual child.”
That accounts for his complete Deity in human form. However, since he came as a human to save humans, a human mother must be involved. He came as one of us, however much unlike us he would always be. Which was exactly the message Paul preached to the Areopagites in Athens, Acts 17. God didn’t send himself as a SPIRIT, meaning the ancient mystery religions had it all wrong. And he didn’t send himself as a STONE, which corrected the Athenians obsession with IDOLS! He sent himself as a MAN, whom he raised from the dead! And when the philosophers heard about the resurrection, most lost interest because they had no concept, interest or use for a resurrected BODY!
