Jesus said to his disciples: ‘You are the salt of the earth. But if salt becomes tasteless, what can make it salty again? It is good for nothing, and can only be thrown out to be trampled underfoot by men.
‘You are the light of the world. A city built on a hill-top cannot be hidden. No one lights a lamp to put it under a tub; they put it on the lamp-stand where it shines for everyone in the house. In the same way your light must shine in the sight of men, so that, seeing your good works, they may give the praise to your Father in heaven.
‘Do not imagine that I have come to abolish the Law or the Prophets. I have come not to abolish but to complete them. I tell you solemnly, till heaven and earth disappear, not one dot, not one little stroke, shall disappear from the Law until its purpose is achieved. Therefore, the man who infringes even one of the least of these commandments and teaches others to do the same will be considered the least in the kingdom of heaven; but the man who keeps them and teaches them will be considered great in the kingdom of heaven.’
