In Chapter Fifty-Two, verses 7 – 8 of his prophecy, in typically colorful and compelling manner, Isaiah provides a picture of a herald or messenger running hurriedly along some Judean  mountain ridge bearing good news for all to hear.  The herald’s feet are happy feet, tapping with joy that God’s people are about to leave captivity and experience restoration and renewal in their homeland.  If the coming of this messenger was joyful, how much more the herald who announces that Jesus, the Son of God has come into this world “to save His people from their sins.” This is the essence of the Christmas story!  This sermon explores that theme.
