17 "Don't misunderstand why I have come. I did not come to abolish the law of Moses or the writings of the prophets. No, I came to accomplish their purpose. 18 I tell you the truth, until heaven and earth disappear, not even the smallest detail of God's law will disappear until its purpose is achieved. 19 So if you ignore the least commandment and teach others to do the same, you will be called the least in the Kingdom of Heaven. But anyone who obeys God's laws and teaches them will be called great in the Kingdom of Heaven. 20 "But I warn you-unless your righteousness is better than the righteousness of the teachers of religious law and the Pharisees, you will never enter the Kingdom of Heaven!

Commentary on Matthew 5:17-20
(Read Matthew 5:17-20)
Let none suppose that Christ allows his people to trifle with any commands of God's holy law. No sinner partakes of Christ's justifying righteousness, till he repents of his evil deeds. The mercy revealed in the gospel leads the believer to still deeper self-abhorrence. The law is the Christian's rule of duty, and he delights therein. If a man, pretending to be Christ's disciple, encourages himself in any allowed disobedience to the holy law of God, or teaches others to do the same, whatever his station or reputation among men may be, he can be no true disciple. Christ's righteousness, imputed to us by faith alone, is needed by every one that enters the kingdom of grace or of glory; but the new creation of the heart to holiness, produces a thorough change in a man's temper and conduct.
