God didn't ask her permission any more than He asked Moses' permission, or Jeremiahs's, or Gideon's, or Samson's, or the Apostle Paul's, or any other of a whole host of people whose lives He crashed into with an assignment they weren't looking for and didn't necessarily want.
Now, I have to believe that Mary was thrilled to be chosen to be the mother of the Messiah. No doubt that would be the dream of any Jewish virgin girl, so of course she would have *accepted* the assignment.
But the angel didn't ask her, he TOLD her how it was going to be. She could either accept it or fight it.
First Jewish mother: OH; my son is so smart; he is a doctor.
Second Jewish mother: But my son is so wise; he is an appellate judge.
Third Jewish mother: My son is the Son of GOD.
That denies our free will... Would you apply the same standard to Eve?
