"Will give birth to Son.They will give Him the name Immanuel.This means "God with us".Matthew 1:23  

"Prince of Peace. ..” Isaiah 9:6

 Some years ago  a postcard of Christmas was published that called a lot of the attention.the postcard was called "IF CHRIST NOT TO HAVE COME". Had its base in the words of our Savior." If  I am he had come". The postcard presented an evangelical shepherd that in the morning of Christmas was asleep in its office and sleeping had a dream with a world where Jesus never had come. 

In the dream the shepherd was in his house and he could not see the boots and socks that in Christmas the children place in the chimney, could not listen bells to sound, left along the streets and did not find churches with towers indicating the sky.Returned home, sat down in the library and all the books that spoke of the Teacher had been lost. 

The bell of the door listened and a boy asked that went to visit its sick mother that was dying.  Immediately it was with him and when tried to console the sick lady opened its Bible and finished in the old testament, not was the new one, there was not hope, there they were not promises of salvation so cried of desperation.  Two days later the sick woman died and the shepherd was in the funeral and when he tried to seek words of consolation and hope of resurrection he did not find anything, only "dust to the dust" and a long and eternal bye.  Finally in the dream he realized that Christ had not come. 
Finally it awoke and was very happy when listened to sing the chorus of the church: 

You COME FAITHFUL ALL, TO BETHLEHEM we GO WITH TRIUMPHANT JOY OF LOVE.. 

"Greatness and honor to our God in the highest heaven and peace on earth among men who please him"....

We have to be very happy today because He has come and we should recall the annunciation of the angel "I bring you good news of great joy which is for al people.Today, one who saves from punishment of sin has been born in the city of David.He is Christ The Lord."Luke 2:10,11. 

We should ask to God help us to spread his kingdom among those that live in pagan countries and they lack a blessed one I gave of Christmas.
