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. A city set on a mountain cannot be hidden. Nor do they light a lamp and then put it under a bushel basket; it is set on a lampstand,where it gives light to all in the house. Just so, your light must shine before others, that they may see your good deeds and glorify your heavenly Father.
"Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. Amen, I say to you, until heaven and earth pass away, not the smallest letter or the smallest part of a letter will pass from the law, until all things have taken place.
Therefore, whoever breaks one of the least of these commandments and teaches others to do so will be called least in the Kingdom of heaven. But whoever obeys and teaches these commandments will be called greatest in the Kingdom of heaven."
