Written in 1984 and released in 1991, the popular Christmas song Mary Did You Know? has reached the top ten songs on two different Billboard charts. But it is an odd song – the questions don’t really ever get answered and some are not even worth asking! From a biblical perspective, it is a better option to ask of her questions we already have answered. What did Mary know? In Luke, Mary’s praise of God in the presence of Elizabeth demonstrates a surprising depth of faith and biblical acumen. She might not have known everything, and certainly had many lingering questions, but we can learn much from what Mary knew.
