What Child is this? Our perfect Savior and Substitute! The joys of the Christmas season go on and on as we visit Jesus in His boyhood. Already as a child, we see Jesus serving as our substitute, perfectly obeying God's law in our place. He does this so that one day He could lay down His sinless life as the sacrifice for our sins. Pastor's sermon, "Already About His Father's Business," is based on Luke 2:41-52.
