What does the Bible say about the role of angels in the Christmas story?

Angels play a significant role in the Christmas story, particularly in announcing the birth of Jesus. In Luke 2:14, they proclaim, 'Glory to God in the highest, and on earth peace, goodwill towards men.' This underscores the angels' joy in God's plan of salvation. They did not envy humanity even when Christ chose to redeem us instead of them, as evidenced in their celebrations. Their song signifies the acknowledgment of God's glory and His goodwill toward mankind in the incarnation of Christ, echoing the profound impact of salvation on both heaven and earth.
