Matthew 5:13-16 - The Sermon On The Mount: Salt And Light
13 "*You* are the salt of the earth; but if salt has become tasteless, in what way can it regain its saltness? It is no longer good for anything but to be thrown away and trodden on by the passers by.
14 *You* are the light of the world; a town cannot be hid if built on a hill-top. 15 Nor is a lamp lighted to be put under a bushel, but on the lampstand; and then it gives light to all in the house. 16 Just so let your light shine before all men, in order that they may see your holy lives and may give glory to your Father who is in Heaven.
