Advent is the season of the year when Christians remember and celebrate the “arrival” of Jesus. But in order to respond rightly to Jesus, you have to understand who he is and why he came. That is a deeply contested question in our culture, but Mary’s story in Luke 1 helps us makes sense of it. Over the next three weeks, we’ll look at her response to the angel’s message. And when we understand the message Mary heard, we’ll be able to respond in the way Mary did.
