What do you think about this?

I was thinking about writing a story about angels, demons, heaven, hell, God, Lucifer, and the Archangel Michael. Here's what I thought of: Lucifer was on heaven, where he fell in love with a human. the woman, then didn't want to be with him when he told her that he was in fact an angel. After she said that she never wanted to hear or see him again, that's when he begins to hate humans. He falls from Grace and becomes the Devil. The woman was pregnant, and had a baby girl. Growing up her whole life she's known that she was different from everyone else, she could voices in her head, start fires with her mind, levitate things, and at times for some reason read people's mind. The Archangel Michael, even though he had greater things to do, he always watched over her. Since he was the one sent Lucifer away. Demons are after her, so they can bring her before Lucifer. She's supposedly the one who start the Apocalypse. The Angels are protecting her. Oh yeah, and her mom died. The Demons killed her, because she would not had over her daughter to them. So yeah, that's what I have. That's what I thought of. What do you guys think? And it's not to be taken to the heart. It's my story.
