Matthew 5:13-16 - The Sermon On The Mount: Salt And Light
13 "You are the salt of the earth. But if the salt loses its taste, how shall it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.
14 You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do they light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
