“Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.” – John 8:12
From the very beginning the Lord’s Advent was associated with light. It was prophesied of His coming, “The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined.” When the Lord was born, the shepherds saw a great light, and it was a star that led the wise men from the east to the place where the young child lay.
It is clear that the Lord is meant in the words, “Arise, shine, for thy light is come, and the glory of the Lord is risen upon thee… The sun shall no more be thy light by day… but the Lord shall be unto thee an everlasting light, and thy God thy glory.” And of the Holy City it is written, “There shall be no night there; for the Lord God giveth them light.” Throughout the Scriptures the Lord is spoken of as the source of light. In the opening verses of the first chapter of John the Lord as the Word is six times spoken of as the light of the world, and in the eighth chapter He declares positively, “I am the light of the world.”
Why is so much said in the Word regarding light, and why is the Lord so often associated with it?
