It is to wipe it out entirely:
The Law of Moses is a burden. Grace doesn’t make the law any less of a burden. Life in Christ doesn’t make the law any less of a burden. Peter addressed this in Acts 15 when some Pharisees said it was necessary for Gentile believers to keep the law.
First, note what Peter didn’t say. He didn’t say, “Well, now that they have Christ, they indeed are able to and should keep the law.” To the contrary, he said to those Pharisees, “Why do you test God by putting a putting a yoke around the neck of the disciples which neither our fathers nor we were able to bear?”
For centuries the law had been a burdensome yoke for the Jews, and it doesn’t become any less of a burden for those who believe in Christ who try to live by it. The law was always meant to be a burden. Its purpose was to point people away from self-righteous justification to justification by faith in Christ alone.
In Christ, God has removed the burden.
