Christmas is not just about the birth of a baby (after all, babies are born all the time). Christmas is about the Birth of one particular Baby–the very Son of God who was born of the Virgin Mary. More than that, Christmas is truly all about the Son of God taking on human flesh for us sinners. Johann Gerhard leads us in pondering “The Mystery of the Incarnation.”
