“The people who walk in darkness will see a great light. Those who live in a dark land, the light will shine on them.” [Isaiah 9:2] Those words from the prophet Isaiah told of the coming Prince of Peace, and of the light and life He would bring.
Christmas arrives again with all the promise of remembrance and celebration. Christians celebrate Christmas because the light did dawn. The birth of Jesus in Bethlehem was not only the fulfillment of biblical prophecy, but the dawn of a new age. As the angels declared to the shepherds, this infant is “a Savior, who is Christ the Lord.”
This is the very essence of Christmas: The birth of the Savior. To understand Christmas is to know that the ultimate peace the Savior would bring would be established by His death and resurrection. Even as Jesus came to save His people from their sins, Christ’s birth points towards His cross and the fulfillment of His saving work.
When Isaiah told of the coming Prince of Peace, he spoke of light dispelling darkness. The metaphor of light is central to our celebration of Christmas. After all, even as John introduces his gospel by identifying Jesus as the Word who became flesh, John also describes Jesus as “the True Light which, coming into the world, enlightens every man.”
The image of light dispelling darkness is central to our understanding of the incarnation and its meaning. When Jesus was presented at the temple shortly after His birth, the aged Simeon recognized this child as “A Light of revelation to the Gentiles, and the glory of Your people Israel.”
The metaphor of light makes sense only against a background of darkness. In the Bible, darkness is a rich metaphor that points to a double reality. In one sense, darkness points to the simple fact of human ignorance. Those who are “in the dark” are those who lack knowledge. To the Jewish mind, this metaphor had particular application to the Gentile world–a world that had not received the grace of God through the revelation of the Torah, the prophets, and the written revelation of God. Even today, we know that untold millions still dwell in deep darkness, having never heard about the one true God or of Jesus Christ, His only Son.
In a second sense, darkness refers to evil and willful blindness. This points beyond the mere fact of simple ignorance. In this sense, darkness refers to the fact that many will reject the light. As John explained, “He was in the world, and the world was made through Him, and the world did not know Him. He came into His own, and those who were His own did not receive Him.”
