The twenty-fourth ornament is an angel, which symbolizes the angels that proclaimed the coming of Christ. An angel is a messenger and usually is sent to tell good news. The angels that proclaimed the coming of Christ got the best job angels could get. They got to tell the best news of all time: Christ is born!
But their job didn't stop there, or maybe it was just a benefit they received from doing their job well. After they told the good news that Christ was born, they broke out in praises to God, saying,
"Glory to God in the highest,
and on earth peace to men on
whom his favor rests."
Thankfully, although the shepherds were the first to hear the good news, God has allowed all of us to hear it as well. We can also sing praises to God for this wonderful gift of His son, Jesus Christ.
