What Sha’ul is really talking about in Romans 3:28 when he employs the Greek phrase "ergon nomos," translated in KJV as "deeds of the Law," is in actuality a technical phrase that the Judaisms of his day employed to speak of their halakh'ot (their group requirements). Thus, if a non-Jew wished to join Isra'el, such a person had to convert and become a Jew first. To be sure, this is one of the primary arguments delineated in the letter to the Galatians.

But for Sha’ul no such 'man-made' conversion policy existed in Scripture!

By contrast, Sha'ul taught most assuredly that Gentiles were grafted into Isra'el the same way that Avraham was counted as righteous by God in B’resheet (Genesis) 15: faith in the promised Word of the LORD. If we understand that quite often Sha'ul’s use of the term circumcision is actually shorthand for "proselyte conversion" then Romans and Galatians begins to make more sense Hebraically and contextually.

God is the God of both Jews and Gentiles! One need not change his station in life before God can accept him. What is more, the real change that takes place in a person’s life is effected by the Ruach HaKodesh when, because of Yeshua’s bloody, sacrificial death, the sinner takes on the status of righteous! A conversion to Judaism (a.k.a. circumcision), in Sha'ul’s mind, added nothing to those wishing to be counted as true Isra'elites in the Torah Community. To Sha'ul, their genuine faith in the Promised Word of HaShem, as evidenced by the genuine working of the Spirit among them, was all the "identity" they would ever need! Once counted as righteous by the Righteous One Himself, all the new [Gentile] believer needed to do was begin to walk in that righteousness, a walk already described in the pages of the Written Torah, a walk formerly impossible due to the deadness of flesh and imprisonment to sin.
