Luke 2:8-20 (NIV)

And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. But the angel said to them, "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. This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger." 

Suddenly a great company of the heavenly host appeared with the angel, praising God and saying, 
"Glory to God in the highest, 
and on earth peace to men on whom his favor rests." 

When the angels had left them and gone into heaven, the shepherds said to one another, "Let's go to Bethlehem and see this thing that has happened, which the Lord has told us about." 

So they hurried off and found Mary and Joseph, and the baby, who was lying in the manger. When they had seen him, they spread the word concerning what had been told them about this child, and all who heard it were amazed at what the shepherds said to them. But Mary treasured up all these things and pondered them in her heart. The shepherds returned, glorifying and praising God for all the things they had heard and seen, which were just as they had been told.

COLOSSIANS 1:26-28 (NIV)

I have become its servant by the commission God gave me to present to you the word of God in its fullness - the mystery that has been kept hidden for ages and generations, but is now disclosed to the saints. To them God has chosen to make known among the Gentiles the glorious riches of this mystery, which is Christ IN YOU, the hope of glory.

We proclaim him, admonishing and teaching everyone with all wisdom, so that we may present everyone perfect in Christ. To this end I labor, struggling with all his energy, which so powerfully works in me.
