Advent Song - starts with "What do you see to brighten the darkness of the world?

[Guest]

Trying to find this song - can't remember name or artist - it is an older song. What do you see to brighten the darkness of the world? One small candle aflame. Will its' light grow, will it spread? Will it burn till the earth is on fire at the sound of His name? Emmanuel, Emmanuel, Jesus, Jesus my Lord.
