The meaning of Christmas is not Santa Claus and gifts.
The meaning of Christmas is, in the (paraphrased) words of the Grinch, "something a bit more".
So while you gather round the tree to open those gifts (from Santa or others) tomorrow morning, remember that this simply wouldn't be, if it weren't for the plan that God set in motion at the beginning of Time when we Fell from grace.
Christmas wouldn't exist, and we would still be a "people crying out in darkness" and waiting desperately for God's promise of a Savior to be fulfilled.
Yes, Christmas is a season of joy for most, but even amongst all those cups of eggnog and all those roasted chestnuts and every single scrap of paper and ribbon, never forget the reason for which that blessed baby boy was born as one of us.
We cannot have Christmas without Good Friday and Easter, because without the cross and the empty tomb, Christ's birth means nothing.
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. (John 3:16)
Christmas is God for us, forever. It is one of the central moments in all of human history, and so it is fitting that we celebrate the birth of our most precious Savior with festivities and gift giving and lots of twinkling lights. But let us remember why He became man, and as we gather around Word and Sacrament tonight and tomorrow morning in our brightly light churches, that we receive Him, God with us, Immanuel.
