In His Sermon on the Mount, Jesus said,

“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 tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.” Matt 5: 17 - 20

When was the last time you read any of the ‘law’ books in the Bible – Genesis, Exodus, Leviticus, Numbers or Deuteronomy? Some of it can be hard going, but all of it is God’s Word. Not all the commands are practised by Christians today (for example, child circumcision, animal sacrifice), but every instruction tells us something about God and the world we live in.

Jesus said he came to fulfill the law. What does that mean?

Some have suggested that the whole of the Old Testament (including the law books), can be summarised by Deuteronomy 6: 4 – 5: “Hear, O Israel: The LORD our God, the LORD is one. Love the LORD your God with all your heart and with all your soul and with all your strength.”[1] Jesus agreed with this and then added, “Love your neighbour as yourself” in Mark 12:29 - 31. In fact, it can be argued that much of Jesus’ teaching was rooted in quotes or principles found in the Old Testament. We see this in the next section of the Sermon on the Mount. For example, “You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. (Matthew 5:27-28)

Jesus fulfilled the law by teaching a deeper understanding of it.

Another way Jesus fulfilled the law was by pointing us to the Father, so that we may obey Him and love Him. We know the law was given to reveal God’s holiness, to set Israel apart from the other nations, define and expose sin, introduce justice and point us to Christ. But it was also given to reveal the heart of God.

Every commandment and every principle said something about God’s love, generosity and kindness. And they revealed a holy God who will judge. So for those who never saw past a list of do’s and don’ts, Jesus embodied The Lord’s love and holiness. He fulfilled the law by living it for all to see. No wonder he said that those who practice the commands (those who follow His example) will be called great in the Kingdom of Heaven. Not in a self-righteous way like the Pharisees but like Jesus – motivated by a desire to please His Father in Heaven.
