The devil and his followers thought they could be like God by their own choice.
But Michael, whose name means “Who is like God?”, represents the fact that it is only by God’s sovereign choice that we can be exalted to his throne.
The battle between pro-life and pro-choice is the same battle. They are wrong who think that the only thing that matters in the end is their own choice, or that such a choice determines right and wrong.
Rather, it is God’s choice that matters, and when he chooses to create a little child, it is our duty to welcome and protect that precious gift.
