In Box #15 there are many gold "halos" representing the multitude of angels
"Suddenly a great company of the heavenly host appeared with the angel, praising God ans saying, 'Glory to God in the highest; and on earth peace to men on whom his favor rests.'"
Can you imagine what it would have been like? The lowly shepherds were out in the fields at night. Suddenly, an angel of the Lord appeared and spoke to them. They were terrified but the angel spoke of the Good News which was nearby. Then, the skies were filled with angels giving praise to God. A life-changing experience!
The shepherds got a glimpse of heaven, but soon they would meet the One who would provide the only way to get to heaven. God's Good News had arrived for all men!
