Christmas, many churches today switch them off and bedeck the aisles with candles! These pictures are from fbb's place of worship last evening.
John, Gospel writer No 4 penning his words son 60 years after Jesus rose from the dead, set out to explain the purpose of Jesus' coming to earth. The narrative was, by then, well established and well accepted but John wanted to explain why.
In the beginning the Word already existed; the Word was with God, and the Word was God. From the very beginning the Word was with God. The Word was the source of life, and this life brought light to people. The light shines in the darkness, and the darkness has never put it out.
"The Word" clearly equals Jesus, but how? Think of the English epithet "say the word and it will be done." What word? When you "say the word", you have authority and stuff happens - Jesus was the Authority of God On Earth - he says and it happens.
This was the real light - the light that comes into the world and shines on all people.
The Word became a human being and, full of grace and truth, lived among us. We saw his glory, the glory which he received as the Father's only Son.
He brings "light" to earth and offers "glory" eternally in Heaven.
That's the power of Christmas.
