Ye are the light of the world.
A city that is set on an hill cannot be hid.
...whosoever heareth these sayings of mine, and doeth them,
I will liken him unto a wise man, which built his house upon a rock:
And the rain descended, and the floods came,
and the winds blew, and beat upon that house;
and it fell not: for it was founded upon a rock.
