 For all Mary knows, like any other Jewish woman of her time who would have loved the honor of being the mother of the Messiah, she thought this might come about through natural means. But she simply says, hey, this isn't even possible because I'm a virgin. And this is why a lot of scholars think that right here we have some evidence for the fact that Mary was always planning to be a virgin. In fact, she may have taken a vow of virginity. There's some early Christian texts that are not in the Bible.
