Christian: Who Are You?
"You are the salt of the earth. But what good is salt if it has lost its flavor? Can you make it useful again? It will be thrown out and trampled underfoot as worthless.
You are the light of the world--like a city on a mountain, glowing in the night for all to see. Don't hide your light under a basket! Instead, put it on a stand and let it shine for all. In the same way, let your good deeds shine out for all to see, so that everyone will praise your heavenly Father.
Matthew 5:13-16 NLT
