Matthew 5:17-20

17“Do 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 truly I say to you, until heaven and earth pass away, not one letter or stroke of a letter will by any means pass from the law until all is accomplished. 19Therefore whoever does away with one of the least of these commandments and teaches others to do likewise will be called least in the kingdom of heaven, but whoever practices them and teaches them will be called great in the kingdom of heaven. 20For I tell you, unless your righteousness surpasses that of the scribes and Pharisees, you will certainly not enter the kingdom of heaven.
