Who wrote this story?

I read (awhile ago) a story about a man who had to go on a trip of some kind, and he was given a lantern because something about being out in the night... Anyway, he was blind, and the lantern ended up going out, and I'm not sure what happened, someone asked him how he got where he was going and he said, I dont need light i have light of god to lead me or somthing like that... It might have been Chinese, though im not positive... Any help would be greatly appreciated.
