Once Jesus has clarified the role of the disciples - to be salt and light to the world, he then explains what that involves. He covers certain elements that are necessary to demonstrate that those who follow him are indeed following him and honouring God.
Matthew 5:17–26 (ESV):
“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. 18 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. 19 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. 20 For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”
Those who had been hearing Jesus up to this point may have been rejoicing because they had not heard teaching like this before, so they thought that he was usurping the Law. Therefore Jesus makes it clear to his listeners that this is not the case, he is in fact fulfilling the Law and Prophets. Jesus is embodying and bringing to life the very words of God - the Scriptures the Israelite people were trying to learn and follow. As the Son of God, Jesus was there when the Law and Prophets were written so he knows the intent and purpose of the Law and he taught what they really mean and demonstrated this through the life he lived. Jesus followed both the Law of God, and the law of the land, he paid taxes, took part in Jewish celebrations, and went to synagogue. His teaching rather than radically dismissing the Scriptures, radically explained them. Over the centuries that had passed since the Torah had been written the true understanding of what they meant had weakened, rituals and ceremonies had become commonplace to try to put into action what people thought The Law meant. So Jesus clarified and upheld the intended meaning and purpose of the Law which was to showcase a pure and holy God, and to bring His people to Himself.
Jesus obeyed The Law, he embodied it. He encourages his hearers to be law abiders, not breakers, too. Yet Jesus does not stop there - he also tells those listening that they have to be more righteous than the Scribes and Pharisees! These were the religious men who; study, debate, and teach Scripture all day and who do their best to obey and enforce every ritual. Jesus is saying that those who honour God have to be more righteous than them! This would have been shocking for those that heard Jesus say this, it is a high bar to attain as these religious men were the holiest people the Jews knew!
However, Jesus was saying that even these religious men were not righteous enough and they won’t get into heaven. So what hope is there for the rest of humanity?
The Pharisees and Scribes were well educated and revered men, experts at recounting the Law and Prophets, following rituals and teaching others to do the some. They were not very good at understanding that true righteousness is displayed in the relationships that they have both with God and other people. Jesus was explaining to those around him that righteousness is not about knowledge, rituals, rules, or giving sacrifices. This was incredibly radical news, for this is what the Israelites had heard and lived for generations. They knew as Israelites that they were a set apart by God as favoured people. This meant that God had caused them to live differently to surrounding nations, in order to be kept pure and made right with God through different rules and practices. They had certain celebrations and sacrifices to make to honour God and be made right with Him. The Pharisees oversaw and taught these things. They were the ones trying to teach the people The Law and how to follow it, as Jesus is saying, so how can anyone ese match the level of righteousness required to enter the kingdom of heaven? That is the point. No human on Earth could attain pure righteousness. Except one, and that is Jesus. He was the only one capable of living the perfect life of being more righteous than every religious leader because he is the Son of God.
Even though Jesus was tempted and suffered just like the rest of us do, he never sinned. His righteousness truly outstripped that of the Scribes and Pharisees. He lived and understood The Law in a different way than they did, for Jesus knew the Law writer personally. He was with God, his Father as it was written and given. So Jesus could understand, demonstrate and explain righteousness in a way no-one else could. Jesus made it clear that even ordinary people can be made righteous, you do not have to know it all, have it all or follow all the routines and rituals, but still you can be made right with God. Jesus did not just create the problem of righteousness seeming unattainable, but he gave his life so that righteousness can be accessed to anyone and everyone. Jesus was the perfect fulfilment of The Law. He followed and obeyed it perfectly. This was so that he could generously give up his life to make atonement for your sin. Now you too can be made righteous, more righteous than the most righteous people you know! If you trust and believe that Jesus is the Son of God who died for all sin, giving you a new life of purity, and you follow him, you can be made righteous. For when you turn and believe in Jesus, God no longer sees you and your wrongdoings, but he sees His perfect son, Jesus. You get to receive his righteousness. You don't deserve it, you haven't earned it and you haven't kept the rules, but you can be righteous and keep being righteous all because of Jesus!
Following Jesus is the only way that you can be made right with God and become righteous than the Scribes and Pharisees. There is no other way. You cannot try hard enough, follow enough rules, know enough, or be kind and generous enough to earn your way into heaven. It is only through accepting that you can be made righteous through the love, life, death and resurrection of Jesus that you are made right before God. So, do you desire to be right before God? If so, trust in Jesus. He made the impossible possible for those who believe in him. When you accept him and his forgiveness and learn to follow him, then you become more righteous than the Scribes and Pharisees and able to enter the kingdom of heaven!
