The Lord is my light. 

Yea, though I walk through the shadow of unkindness, I must smile, for the beauty of the Lord is upon me; my countenance is filled with light, the light of love, patience and endurance.

I shall strive to give joy to the sorrowful, hope to the light, sunshine to the darkness, and I shall remain a door-keeper in the House of the Lord, as long as I live.
