The central message of this sermon is that the true significance of the Christmas story lies not in its details, but in understanding the profound nature of Jesus' identity as a Savior who saves from sin. The preacher argues that many people misunderstand the purpose of Jesus' birth, thinking he came only to be an example or role model, rather than to actually save people from their sins. By examining the six "serving men" - what, why, when, how, where, and who - the sermon reveals that the Christmas story is about a divine Savior who has come to overcome sin, death, and despair. The preacher emphasizes that Jesus' identity as Christ, or Messiah, refers to his divinity and role as God incarnate, and that this reality is at the heart of Christianity. The takeaway from this sermon is that true understanding of the Christmas story requires a deeper grasp of Jesus' nature and mission, which transcends mere historical or cultural significance.
