This sermon begins a four-part preaching series through Matthew 1–2, The Birth of Jesus Christ. The story of Jesus' birth begins with his backstory, his genealogy. Genealogies are important for a variety of reasons. In the case of the Messiah, genealogies give us confidence that he really is the One. Specifically, that he is the great son of David, the one promised who would save his people from their sins. But, more than that, that we can be one of his.
