Matthew 5:16-18

16In the same way, let your light shine before men, that they may see your good deeds and glorify your Father in heaven.

17Do not think that I have come to abolish the Law or the Prophets. I have not come to abolish them, but to fulfill them. 18For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished.
