I am the good shepherd. I know my own and my own know me, just as the Father knows me and I know the Father. And I lay down my life for the sheep. (John 10:14-15)
Jesus said to his disciples: “You are the salt of the earth. But if salt loses its taste, with what can it be seasoned? It is no longer good for anything but to be thrown out and trampled underfoot. You are the light of the world…” Matthew 5:13–14
