Come, Light of Lights is layered song composed by Ruth Cunningham that can also be sung as a 2, 3 or 4-part canon/round. 

The song is useful as an invocation or introit, a call to prayer, or a sung Prayer for Illumination. Many communities also sing it during Advent.

Come, wisdom of Spirit into my heart."
