Sam, too, needs to hear that message. It's partly because he carries the burden of serious misdeeds. Those sins are the symptoms of his conviction that nobody but himself really matters, and he's not even sure about himself anymore. He knows that other people know it's time to get ready for Christmas. He just can't imagine what that would mean.
Advent begins with an invitation to repent and be forgiven.
So often the Christmas season looks like an excess of tinsel and an excuse for a party. The future seems as empty as the past. The focus is on us and what we want and our fury that we cannot have everything we want. It's as foolhardy as expecting a garden where none has been planted. It's as that we do not earn our forgiveness nor do we merit the gift of Christmas.
