The story of Christmas comes from the Bible. Here is the way it is told by Luke 2:7-16...

And she brought forth her first born son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.

And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And lo, the angel of the Lord came upon them, and the glory of the Lord shone around about them; and they were sore afraid. And the angel said unto them,

"Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto to you is born this day in the city of David a Savior, which is Christ the Lord. And this shall be a sign unto you; ye shall find the 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, good will toward men."

And it came to pass, as the angels were gone away from them into heaven, the shepherds said one to another,


"Let us now go even unto Bethlehem, and see this thing which is come to pass, which the Lord hath made known to us."

And they came with haste, and found Mary, and Joseph, and the babe lying in a manger.
