Lk.2:9-11 – And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with great fear. And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord”.
The shepherds caught a glimpse into the world of angels that day. Obviously, angels have a different perspective. You would have to say they have a more clear perspective of the Lord, their eyes not encumbered by a fallen nature and not living in a fallen creation like us. The angels have had a clear vision of the Lord since the day they were created. Seeing the Lord in their unfiltered world gives them an accurate picture of the greatness of the Lord. No wonder they are worshipping, they see Him in His glory, the only response is worship or outright rebellion. Here are some comments from Martin Luther on this glimpse into the world of angels.
“We can learn from this song what kind of creatures the angels are. Do not consider what earthly philosophers dream about them. Here they have all been painted in such a way that they could not be painted better, so that even their heart and thoughts may be known. First, when they sing glory to God with joy, they show how full of light and fire they are. They acknowledge that all things are God’s alone, attributing nothing to themselves; instead with great fervor they give the glory only to him to whom it belongs. Therefore if you want to think of a humble, pure, obedient and joyful heart praising God, think of the angels. This is the first part of their walk before God.”
In this passage we see the angels delving into an arena they could never understand. They are announcing the birth of a Savior, Christ the Lord. To the angels salvation is a mystery. Christ didn’t take on an angelic body to redeem angels from their sin. He became a man to save us. The righteous angels don’t need a Savior, therefore there is a song, the song of redemption that they can never sing. They are announcing the Savior to the shepherds, it will be our responsibility to worship Him as the Lamb of God, the Savior of the world.
