Historically the busiest day for buying Christmas presents is the Saturday before Christmas and the second is Christmas Eve. This year both of those fall on Saturday, December 24.
So my suggestion is that we greet each other with "Survive Christmas Frenzy time".
It seems easy to lose Jesus amid the hurry and scurry of finding that perfect present and the varied activities of celebrating the season. It's easy to reduce Him to a catch phrase, "the reason for the season!!"
Yet, He IS the reason for the season. His birth was heralded as welcome to the Savior of the world. And through Him we have the promise of life forever with God Almighty.
For there's born to you this day in the city of David a savior, who is Christ the Lord. And this will be a sign to you: You will find a babe wrapped in swaddling clothes, lying in a manger. And suddenly there was with the angel a multitude of the heavenly host praising God and saying: Glory to God in the highest, and on earth peace, goodwill toward men (Luke 2:11-14).
So maybe we should say to each other, "Thank God for Jesus."
