Matthew 5:13-16 - The Sermon On The Mount: Salt And Light
13 "Ye are the salt of the earth; but, if the salt become tasteless, with what shall it be salted? It is henceforth good for nothing, except, when cast without, to be trodden under foot by men.
14 "Ye are the light of the world: a city, set upon a hill, cannot he hid. 15 Nor do they light a lamp, and put it under the measure, but on the lamp-stand; and it gives light to all who are in the house. 16 So let your light shine before men, that they may see your good works, and glorify your Father Who is in Heaven.
