Moreover, a few verses not routinely interrogated along these lines (Rom 4:11–16) suggest that Paul continued to regard the Law and its keeping as a defining characteristic of Jewish social identity that he expected to perdure at least until the general resurrection. Such expected Law-keeping does not function at the soteriological register, as if Paul thought Jews merited salvation by Law-observance; rather, according to Paul’s reasoning, such Jewish Law-keeping expressed their belonging to those “of the circumcision”, a people whose existence and perdurance Paul regards as ordained by God as one of the nations comprising Abraham’s promised “seed”.  - Paul T. Sloan, Jewish Law-Observance in Paul.
