As Matthew begins his summary of Jesus’ teachings from the mountain he wants to make Jesus’ intentions clear. This sermon is not a supplement to the teachings found in the Law. Jesus is not replacing the Law with the Law 2.0; a brand new teaching that is better than the original. Jesus makes his intentions clear in Matt 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.”
How does Jesus fulfill the Law? The Law says that you need to include a railing when you build a second floor balcony on your house (Deut 22:8). The Law says that you need to keep an ox`s mouth uncovered when it is threshing grain (Deut 25:4); Clothing should be made without mixing materials (Deut 22:11); Mildew must be dealt with following a strict set of instructions (Lev 14:33-53). All of these laws have reasons why they were part of the Torah but how does Jesus fulfill them?
The Law has individual verses that are culturally distant from contemporary culture today and as a result some verses are very difficult for us to understand. Because of this, the Law is best understood when it is considered as a whole: The Torah comprehensively described how a member of God’s covenant community was meant to live in the 14th century BC. As a result you can capture the essence of who the people of God were meant to be (and who God is) by understanding the requirements of Law. Some parts of the Law are difficult to understand but that is because God’s thinking is far beyond ours (Is 55:9). When we have a problem understanding the Law, the problem lies with our understanding and not with the Law.
The Law is a witness to the character of God. That is why followers of Jesus today can still read the Law and gain insight into who God is. Just because we live in a time after Jesus’ death, burial and resurrection doesn’t mean we can’t learn about God from the Old Testament too. David writes, “Oh how I love your law! I meditate on it all day long.” (Ps 119:97) If it was good for David it is good for us too!
The Law however is not an end onto itself. Paul says that the Law does not save (Rom 5:20-21; 7:13-233; 8:2-3) but instead, the Law points to the fact that we need a Saviour. In Hebrews 10, the Law is described as a shadow, cast by Jesus Christ. In other words, the law predicted the kind of character Jesus would embody. The law required the blood of animals to temporarily atone for sin so that we would understand that Jesus’ blood atones for sin forever (Heb 10:10). The Law described sanctification in miniature, until Jesus came and lived it out writ large.
Jesus finally accomplishes what the Law said was going to have to happen. In that way Jesus fulfills the Law. Jesus satisfies the Law’s requirements and grants us God’s approval through our faith in Jesus’ obedience (2 Cor 5:21). Just like the Law in the Old Testament, the Sermon on the Mount doesn’t describe a way we can earn God’s approval but rather it describes the person that the Holy Spirit is turning us into. The Sermon on the Mount isn’t God’s wish list for us: “Wouldn’t it be nice if you didn’t hate your boss. You really should try to not lust after your secretary.” The Sermon on the Mount is the character of Jesus Christ which we are becoming day by day through the agency of the Holy Spirit.
