“Works of the law” refers to the do’s and don’ts of the written code. They are works for Israel to do, which if kept, they will live by them, as no curse and judgment according to the law will fall upon them. It bounds all the children of Israel, both those who have or have not faith, even the stranger within their gates, who sojourns with them or are their servants, native born or not who are circumcised.
I already explained in one of my response post, that the matter of having or not having faith has nothing to do with what Paul is saying about the law, that it is not of faith. He is by that, telling what the law is not. He is by that making a contrast between the law that has come to the Jews and the faith that has come to the Christians in Galatia. That the former is not of faith and the latter needless to say, is. He did not say “the law is not of faith”, to make a contrast between Israel (as depending on obedience to the Law for justification) and the Christian (as depending on faith). He is contrasting law and faith, not people nor about people.

I don't think we can separate the people who were under the Law, Israel, from the system of Law itself. So they operated by faith under the Law at times, and sometimes did not. But even when they served the Law by faith, "faith had not yet come."
What that meant was that the object of faith for eternal life had not yet come. That is what I mean by saying that Paul used "shortcuts" in his theological expressions. He had to abbreviate things or he would become too long-winded. He expected us to recognize that he meant Christ was the object of our faith for eternal life.
So Paul was not saying that Israel didn't operate by faith under the Law. He was only saying that the faith that results in eternal life had not yet come, and did not operate that way under the Law, because Christ had not yet come.
The way the Law operated also had grace, just like NT Grace, the difference being, once again, that NT grace provided for eternal life, and OT grace did not. OT grace brought temporary forgiveness of sins, until the next sin was committed. So sin was never completely done away with, in terms of redemption. Final redemption had not yet come.
But the Law did enable Israel to experience blessings that they did not deserve. They were able to avail themselves of grace by which their sins were pardoned, and they could therefore present their obedience with the reward of blessing. They could avoid some of the curses of their failures.
This kind of limited grace still did not achieve for them eternal life. For that Christ had to come and do a perfect work, a divine work, to forgive their sins for all time on behalf of God and His Son, who completely suffered all of their sins.
The limited grace under the Law, therefore, was not the faith that was to come, which would provide for eternal pardon and eternal life. The Law was not of faith, because even though it achieved righteousness, and some blessing, it still could not achieve eternal life. They earned a reward for their obedience, but their obedience was not perfect enough to replace what only Christ could do.
What Paul was saying was that the faith Christians were to have in Christ had not yet come until Christ actually performed his task of eternally redeeming us. That "faith" had not yet come while the Law was still in effect.
The Law had faith, and it produced righteousness, through grace, achieving a limited reward. But the reward Christ brought had not yet come, and that "faith" had not yet come. The things that men could "earn" under the Law was limited, and could never produce eternal life. That had to come when "faith" came.
When Paul talks about us not "earning" Salvation, he is not talking about earning blessings alone. He is talking about earning eternal life.
So it requires faith to obtain grace for something we don't deserve. We do good works, but they never earn for us eternal life, because our sins need to be forgiven and disposed of. Apart from Christ, works under the Law could achieve both righteousness and blessings. But they could not achieve eternal life, because grace needed to cover man's sins completely, and not just for the moment. Christ had to do this by extending his spiritual life as a gift to us.
Abraham exercised faith in order to obtain grace, just as later Israel would obtain grace under the Law. That's because grace only comes by faith, it being that forgiveness is not something that can be earned. And it is able to obtain eternal life once Christ has come and accomplished his work of final redemption.
Paul used "faith" as the means of grace, both obtaining pardon for sin during the era of Law, and finally achieving eternal redemption after Christ came. So "faith" was all important before the Law, during the Law, and in the Christian era.
As such, the Law was not of faith because it only obtained limited pardon, and in fact, disqualified Israel for eternal life. The faith by which they obeyed the Law at the same time prevented them from obtaining final grace. Thus, "faith had not yet come."
