WHAT DOES THE BIBLE REALLY TEACH: Was Jesus a Physical Descendant of Adam?

The apostle Paul tells us in Galatians 4:4 that the Father “sent forth his Son, born of a woman.” How did the laws of heredity work with this union of perfection (the life of the Son) with imperfection (the ovum or egg cell in Mary’s womb)?

How was the life of the Son transferred from heaven to earth to be united, in the fertilization of an ovum or egg cell in Mary’s womb? How could Jesus, as the actual son of Mary, a genuine descendant of forefathers Abraham, Isaac, Jacob, Judah, and King David and legitimate heir retain the same identity that he had in heaven?
