"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 among those with whom he is pleased!" - Luke 2:13-14, ESV.
The angels were doing what they were created to do. They were, amongst other things, intended to worship God and relay messages to humans. This is precisely what they were doing, but not all they were doing.
The angels are sometimes referred to in the Bible as the "Host of Heaven." That is a military term. These worshippers were the armies of heaven. They were in the area to protect the helpless baby Jesus from the devil, who would have destroyed the Messiah. The angels were successful in stopping him, so the devil had Herod try to kill him, too. But that is another story.
Notice that these mighty soldiers didn't sing to the Lord. They spoke, probably in a cadence like militaries do even today. Can't you just hear them? Google a military haka ceremony or look it up on YouTube and see what it could have been like. They were doing their job in true military fashion. They worshipped the Lord in might and told the shepherds that this birth, this baby, was a very big deal.
Fast forward to today. Are you living according to your purpose? Are you living to reflect the glory of the Lord like He made you to do? Are you worshipping well? Or are you quite satisfied with weak-voice witnessing, minuscule glory-reflecting, and dishonoring worship? Just think about it today. Let's live up to God's expectations. - Pastor Mike
