Walk by the Light

"Don't you know that the spirit of man is the candle of the Lord?"
"But so many follow their own fancies--that you must allow, Laird! And what comes of your candle then?"
"The fact that such men never look where the light falls, but always in some other direction, doesn't mean the light's not there just the same. They just don't care to walk by it. But them that order their ways by what light they have, there's no fear of them. Even should they stumble, they shall not fall."
