Matthew 5:13-16 - The Sermon On The Mount: Salt And Light
13 "You are the salt of the earth; but if the salt lose its savor, in what way shall it be salted? It is henceforth good for nothing but to be thrown out and trodden under foot of men.
14 "You are the light of the world. A city built on a hilltop cannot be hid; 15 "nor do men light a lamp, and put it under the bushel, 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 good you do, and give glory to your Father who is in heaven.
