I once read, "What if God had sent Gabriel to many women before he came to Mary many times and they had all refused?" Was he giving Mary a choice? She seems to voice consent. What if she had said no?
Mary said, "Let it be to me according to your word." Wow. What faith it took to say that. She had no idea what she was getting into. None of us who sign up for parenthood, or have it thrust upon us "surprisingly," really know what we are getting into until we experience it. But Mary has more ahead of her than just parenthood. She has the potential disgrace of being unmarried and pregnant. She has the prediction of Simeon, "A sword shall pierce your heart." She has the pain of watching her son leave for ministry; and then the unspeakable horror of watching him die a tortured death.
