It is a great deal better to live a holy life than to talk about it. We are told to let our light shine, and if it does, we won’t need to tell anybody it does. Light-houses don’t ring bells and fire cannon to call attention to their shining — they just shine.

Dwight Lyman "D. L." Moody (1837-1899) American evangelist and publisher

(Attributed)

Sometimes quoted, "they just shine on."
