Rejoice, for the Word was with God and has now become flesh, assuming our nature to unite us to His glory and save us from our sins. This divine and human child, Jesus, bears our sins and sheds His blood for our atonement, offering Himself to us in the sacraments to internalize this salvation. Astonishingly, He who knew no sin became sin for us, taking upon Himself the curse of the law, that we might be freed from sin and its consequences. Rejecting this gift is folly, for even animals recognize their master, and Christ our master offers us not just earthly joys but eternal life. As we receive Him, believe in His name, and embrace the authority to become children of God, we are called to grow into the fullness of Christ, transforming sin into righteousness and death into life. This transformation is the heart of Christmas: God became man so that we might become like God, celebrating not just His birth but His indwelling in us through grace.
