What does a Christmas candle light symbolize in Christmas?
The candle itself symbolizes nothing. However, after you light the candle, than the candle light symbolizes Jesus The True Light of the World.
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)
That was the true Light, which lighteth every man that cometh into the world. (John 1: 9)
