14Ye are the light of the world. A city set on a hill cannot be hid. 15Neither do [men] light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house. 16Even so let your light shine before men; that they may see your good works, and glorify your Father who is in heaven.
Matthew 5:14-16 (ASV)
