Matthew 5:14-16

14 You are the light of the world. A city that is set on a hill cannot be hidden.
15 Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house.
16 Let your light so shine before men, that they may see your good works and glorify your Father in heaven.

17 "Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.
