When the angel told the shepherds of the birth of Christ, a multitude of the heavenly host appeared and praised God! The good tidings made them shout out for joy!
Do we shout for joy at the thought of the birth of our Saviour? Do we praise God for the gift of His Son, and the gift He offers us?
Go tell it on the mountain, over the hills and everywhere! Go tell it on the mountain, that Jesus Christ is born!
Luke 2:7-14 – “And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn. 8 And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. 9 And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. 10 And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. 11 For unto you is born this day in the city of David a Saviour, which is Christ the Lord. 12 And this [shall be] a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger. 13 And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, 14 Glory to God in the highest, and on earth peace, good will toward men.” 
When I was a lonely seeker,
I sought both night and day.
I asked the Lord to help me
and He showed me the way.
He made me a watchman upon a city wall,
and as a Christian, I am the least of all.
So I said, “Go tell it on the mountain,
over the hills and everywhere.
Go tell it on the mountain,
our Jesus Christ is born!
