Matthew 5:17 “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. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
Romans 3:31 Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
Luke 16:17 But it is easier for heaven and earth to pass away than for one dot of the Law to become void.
Galatians 3:17-24 This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise. Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary. Now an intermediary implies more than one, but God is one. Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe. Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. So then, the law was our guardian until Christ came, in order that we might be justified by faith.
Jesus here began a discussion of the law and wanted to make it clear that He did not oppose what God gave Israel in what we call the Old Testament. He did not come to destroy the word of God, but to free it from the way the Pharisees and Scribes had wrongly interpreted it. Jesus wanted to make it clear that He had authority apart from the Law of Moses, but not in contradiction to it. Jesus added nothing to the law except one thing that no man had ever added to the law: perfect obedience. This is certainly one way Jesus came to fulfill the law. Even though He often challenged man’s interpretations of the law, Jesus never broke the law of God. Faith was never to be separated from the law but somehow man had changed faith into works apart from faith. The more laws they could follow without breaking the more righteous they felt they were. It is as if they were defining what it meant to be righteous by following in obedience to many of the man instituted obligations and rules. The purpose behind obedience is not for obtaining righteousness but a person’s life committed to that which honors and glorifies Jesus Christ. Don’t lose sight of this. Too often people try to do good to outweigh what they have done wrong. There is nothing wrong with doing good, but there is an absolute wrong when the good is an attempt to make oneself right before God. Only faith, trust, hope, and reliance on Jesus Christ will right the wrongs in our life.
