You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out & trampled under people's feet.

You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp & put it under a basket, but on a stand, & it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works & give glory to your Father who is in heaven.”

— Jesus, Matthew 5:13-16
