This response is going to sound cryptic and unresponsive but it isn't...Sorry, I’ve been told before that works “of the law” was not talking about the law of Moses.
Of course, my paradigm says different. I see Galatians as the best argument that the law of Moses and the law of Christ are incompatible but let’s start in Romans.
If we look at the language, it’s clear the law was no longer binding to those in Christ.
6:15 What then? Shall we sin because we are not under law but under grace? May it never be!
7:6 But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter.
8:2 For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death.
10:4 For Christ is the end of the law for righteousness to everyone who believes.
Galatians is dealing with circumcision being added to the gospel and Paul gets on to Peter because he is dividing Christ based on circumcision like it was under the law.
Acts 10:28 And he said to them, "You yourselves know how unlawful it is for a man who is a Jew to associate with a foreigner or to visit him;
Paul then says 2:21 I do not nullify the grace of God, for if righteousness comes through the Law, then Christ died needlessly."
He then shows them the law was added but it didn’t change the promise. The law was added so man could see his sins.
Gal. 3:19 Why the Law then? It was added because of transgressions,
Rom. 7:7 What shall we say then? Is the Law sin? May it never be! On the contrary, I would not have come to know sin except through the Law; for I would not have known about coveting if the Law had not said, "You shall not covet."
In seeing their sins they saw they were dead and in need of a savior.
Rom. 7:9 I was once alive apart from the Law; but when the commandment came, sin became alive and I died;
The law wasn’t the promise and it wasn’t meant to continue. I was only in effect until Christ.
Gal. 3:19 Why the Law then? It was added because of transgressions, having been ordained through angels by the agency of a mediator, until the seed would come to whom the promise had been made.
3:23 But before faith came, we were kept in custody under the law, being shut up to the faith which was later to be revealed. 24 Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith. 25 But now that faith has come, we are no longer under a tutor.
There is no division in Christ, there is no Jew or Gentile, just Christian.
3:26 For you are all sons of God through faith in Christ Jesus….28 There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus.
Chapter 4 uses Sarah and Hagar as an example of the Law of Moses and the Law of Christ, one a slave and one free. Christians are free.
Chapter 5 makes it perfectly clear, that no one can be in Christ and follow the law.
5:2 Behold I, Paul, say to you that if you receive circumcision, Christ will be of no benefit to you. 3 And I testify again to every man who receives circumcision, that he is under obligation to keep the whole Law. 4 You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace.
No one can be saved outside of Christ.
Gal. 2:16..... since by the works of the Law no flesh will be justified.
Those verses us used do not show anyone teaching the law or instruction to keep it. The apostles were doing the same thing Paul as doing, picking battles. There are verse where Paul is seen keeping the law of Moses so that in itself should prove the law of Moses is no longer binding.
I rest my case.
Resting in Him,

P.S. I'm very short on time. I'll try to explain later. In the mean time see if you can figure out what I mean. There are several people participating in the thread who will instantly understand the point I'm making. Perhaps they can weigh in on it. Perhaps more than one perspective on the same topic will help me out here.
