12 Be happy and glad, for a great reward is kept for you in heaven. This is how the prophets who lived before you were persecuted.
13 “You are like salt for the whole human race. But if salt loses its saltiness, there is no way to make it salty again. It has become worthless, so it is thrown out and people trample on it.
14 “You are like light for the whole world. A city built on a hill cannot be hidden.
15 No one lights a lamp and puts it under a bowl; instead he puts it on the lampstand, where it gives light for everyone in the house.
16 In the same way your light must shine before people, so that they will see the good things you do and praise your Father in heaven.
17 “Do not think that I have come to do away with the Law of Moses and the teachings of the prophets. I have not come to do away with them, but to make their teachings come true.
18 Remember that as long as heaven and earth last, not the least point nor the smallest detail of the Law will be done away with — not until the end of all things.
