FAQ: Why was Joseph left out of Jesus' conception? Why couldn't he have been Jesus' biological father?
A: There's a few theories going around out there we might consider.
1• Men are filthy, unsanitary beasts. It's unthinkable that God would permit them to contaminate, and thus violate, the womb that was to bear the Holy Son of God.
» Women's bodies are made of material taken from a man's body (Gen 2:21-23). Mr.Job nailed it when he remarked: Who can bring a clean thing out of an unclean? Not one (Job 14:4). You see; women aren't from Venus after all; they're actually from Mars, same as men.
2• It was a measure to prevent the so-called fallen nature from infecting Jesus; which is believed inherited from a child's biological father.
» Well; whence did Eve get it? She was constructed of material taken from Adam's body; but he tasted the fruit after she was born, so it was too late for him to pass the fallen nature on to her via procreation.
3• Joseph was left out of Jesus' conception in order to protect him from the curse upon king Jeconiah's royal posterity (Jer 22:29-30, Matt 1:11).
» That's a very popular theory among quite a few Protestants. However; according to the language and grammar of the curse; its duration was limited to an era when the land of Israel was divided into two kingdoms-- Judah in the south and Samaria in the north --which came to an end when Nebuchadnezzar crushed the whole country and led first Samaria, and then later Judah, off to Babylonian slavery. When Christ takes the reins, the land of Israel will be unified, i.e. it will no longer be Judah in the south and Samaria in the north.
And besides, Jeconiah's royal line and the curse were inseparable. Had the curse been established in perpetuity, then when Jesus was placed in Jeconiah's royal line via his adoption to Joseph, he would've inherited the curse right along with the line; virgin conceived or not would've made no difference.
4• Another theory, which seems to me the most sensible, is that it was simply God's wishes that Jesus be not only Adam's progeny, but also His own, viz: Son of Man and Son of God; consistent with the angel's announcement. (Luke 1:32-35)
