It is a wonderful truth that Jesus fulfilled the righteous requirements of the law for us. But what Paul says here is that God sent His Son into the world so “that the righteous requirement of the law might be fulfilled in us.”

How is that possible? How can you live the life to which God calls you? Perhaps the greatest misunderstanding of the gospel is that Jesus was simply a good moral teacher who told us how to live. And that if we want to please God, we must follow His teaching.

Maybe you are saying to yourself, “If I really focus and exercise self-discipline, I can live a life that’s pleasing to God.” That’s what the Pharisees did. But if you try this, you’ll soon find that it is unsustainable.

You are trying to be something that you are not, and sooner or later, you will say, “I can’t do this anymore. I have to do what I really want to do.”

The only way you can live the life to which Christ calls you is if righteousness becomes your deepest desire. That is why Jesus said to Nicodemus, “You must be born again.” You are trying to live a righteous life, but unless the Holy Spirit brings you to a new birth, you “cannot see the kingdom of God” (Jn. 3:3).

Christ calls you to pursue a life of love, a righteous life, and that is only possible by the power of the Holy Spirit.

Have you been trying to please God in your own power?

This is an astonishing statement. The scribes and the Pharisees devoted their entire lives to the pursuit of righteousness. How could our righteousness ever exceed that of the scribes and the Pharisees?

Jesus was scathing in His critique of the Pharisees, first, because their righteousness was arrogant. The Pharisees liked to pray where they could be seen. Jesus said to His disciples, “When you pray, go into your room and shut the door and pray to your Father who is in secret” (6:6).

The Pharisees liked people to know what they were giving. Jesus said to His disciples, “When you give to the needy, do not let your left hand know what your right hand is doing” (6:3–4).

Then Jesus was critical of the Pharisees because their righteousness was external. “You clean the outside of the cup... but inside they are full of greed and self–indulgence” (23:25). Man looks on the outward appearance, but God looks on the heart.

It would be easy to say, “This is why we need to trust Jesus as Saviour, so we will have His perfect righteousness, which is far better than that of the Pharisees.” This, of course, is true. But it’s not what Jesus is saying here.

Jesus is calling His disciples to the pursuit of a righteous life, a righteousness that is better than the Pharisees, a righteousness that is humble and that comes from the heart.

Can you see some ways in which the righteousness that you are pursuing may be arrogant or external?

Jesus came into the world to fulfil the law and the prophets, and He did so in His life and in His death.

1. In His Life
Isaiah said that a virgin would conceive and bear a son (Is. 7:14). And when Mary bore Jesus, that prophecy was fulfilled. Micah said that the One who would rule and shepherd God’s people would come out of Bethlehem (Mic. 5:2, 4). And when Jesus was born in Bethlehem, that prophecy was fulfilled.

Jesus fulfilled the prophets in His life. And Jesus fulfilled the law in His life. “He who sent me is with me… I always do the things that are pleasing to him” (Jn. 8:29).

By God’s grace, we can sometimes do the things that please the Father, but only Jesus could say, “I always do the things that are pleasing to him.” He fulfilled—lived out—all that the law requires in His life.

2. In His Death
“Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, ‘Cursed is everyone who is hanged on a tree’” (Gal. 3:13). The prophets spoke about a suffering servant who would be “pierced for our transgressions” (Is. 53:5).

In Psalm 22, David depicts a man whose hands and feet are pierced, who is mocked, whose garments are divided by casting lots, and who cries out, “My God, my God, why have you forsaken me?”

Jesus fulfilled the prophets in His death. And Jesus fulfilled the law in His death. The law prescribes blessings for obeying God’s law and curses for breaking it. We have an obligation to the law that we have not fulfilled. And that brings a curse.

But Jesus fulfilled the requirements of the law in His life, and He paid the penalties of the law in His death.

What if Jesus hadn’t fulfilled the law or the prophets?
