Matthew 5:17-20 - The Sermon On The Mount: The Law And The Prophets Fulfilled
17 Think not that I have come to destroy the law or the prophets; I have not come to destroy but to complete. 18 For I tell you truly, that till heaven and earth pass away, one iota or one point shall by no means pass away from the law till all things are accomplished. 19 Whoever therefore shall break one of the least of these commandments, and teach men so, shall be called least in the kingdom of heaven; but whoever shall do and teach, he shall be called great in the kingdom of heaven. 20 For I tell you, that unless your righteousness exceeds that of the scribes and Pharisees, you shall by no means enter into the kingdom of heaven.
