She was told? Last I checked, we had free will.
Go back and re-read the the Bible. See if there was a question that asked her to if she would like to do something. See if there is a verse which she says "yes" in quotation marks. Chapter and verse please.
Yes, she was told.
Luke 1:30-33 And the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end.”
Free will? Where in Scripture is that? Chapter and verse, please.
