Paul objected strongly to the insistence on keeping all of the Jewish commandments, considering it a great threat to his doctrine of salvation through faith in Jesus. For Paul, Jesus' death and resurrection solved this problem of the exclusion of the gentiles from God's covenant. 'Dying for our sins' refers to the problem of gentile Torah-observers, who, despite their faithfulness, cannot fully observe commandments, including circumcision, and are therefore 'sinners', excluded from God's covenant. Jesus' death and resurrection solved this problem of the exclusion of the gentiles from God's covenant, as indicated by Rom 3:21-26.
