"I am the light of the world.
Whoever follows me will never walk in darkness,
but will have the light of life."
Which, like the toad, ugly and venomous,
Wears yet a precious jewel in his head;
And this our life, exempt from public haunt,
Finds tongues in trees, books in the running brooks,
Sermons in stones, and good in every thing.
