Did you know, that “light” is a major theme of the Bible? The Bible says - “God is light, and in Him is no darkness at all.” The first act of creation was - “… let there be light.” Jesus said - “I’m the light of the world.”
On Christmas, the very first Christmas, light played a major role. The angels put on a spectacular light show for the shepherds when they announced - “Behold born this day, in the city of David is a Saviour, Christ, the Lord.” The wise men followed some kind of star that led them from the east to the west to find Jesus.
Light played a major role because Christmas is a celebration of God’s light entering our world. John 1 says - “Before anything else existed, there was Christ with God… His light is the light, that shines through the darkness, and the darkness can never extinguish it.”
