Christ is the end of the law so that there may be righteousness for everyone who believes. Moses describes in this way the righteousness that is by the law: “The man who does these things will live by them.”
Nobody enjoys following rules. This was precisely the problem with the law – it wasn’t kept and couldn’t be kept. This brought problems for the human race because no one was righteous by virtue of following the law.
When Jesus came, He put an end to the burden of the law. The law only served to point out how unrighteous we were because we were unable to keep it. It pointed to the fact that we needed a savior to give us righteousness. Once Jesus came, we no longer needed a reminder because Jesus was our reminder.
Under the law we were trying to gain righteousness by following rules that we couldn’t keep. Under Christ, we are given righteousness by virtue of the fact that Jesus kept the law.
It should be noted that Jesus did not say that it was no longer important to follow the law. The laws that God gave us weren’t without purpose, they were given with our best interest in mind. What Jesus accomplished in the end of the law is that righteousness is no longer gained by following the law. Today righteousness is only through Jesus and the gift of God.
