Matthew 5:17-20

Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. I tell you most assuredly that until heaven and earth pass away, not even the smallest letter or a tiny pen stroke shall in any way pass away from the Law until all things are accomplished. Therefore, whoever breaks one of the least of these commandments, and teach others to do so, shall be called least in the Kingdom of Heaven; but whoever obeys and teaches them - shall be called great in the Kingdom of Heaven. For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven.
