John 8:12: The Light the Advent Candles Point To
The advent candles are a tradition, not a command of Scripture. John 8:12 names the light they point toward: Jesus himself, who promises that the one who follows him will not walk in darkness.
John 8:12: Jesus, the Light of the World
Jesus does not offer himself as one light among many. In John 8:12 he claims to be the light of the world and names following him as the way out of darkness.
