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.

THEN WHAT DID JESUS TELL THEM?

1). "Thus shall it be for you, for the just man is a light in the darkness to the upright."
2). "Just so, your light must shine before others, that they may see your good deeds and glorify your heavenly father."
3). "You are the salt of the earth, and the light to the living that shall shine through the darkness."
4). "Just so, when you light a lamp, place it not under a bushel basket, for that is a known fire hazard."
