STOP AND THINK I heard the bells on Christmas Day. Their old, familiar carols play, and wild and sweet the words repeat of peace on earth, good will to men! (Henry Wadsworth Longfellow)

Yes, this is the day that has changed the world. Even our calendars are arranged because of Christmas. (B.C. – “before Christ”; A.D. – “Anno Domini” [the year of our Lord]). But, far more important, it is the day when we celebrate the birth of the Savior.
 
Do not be afraid. I bring you good news of great joy that will be for all the people. Today in the town of David a Savior has been born to you; he is Christ the Lord. (Luke 2:10-11)
