“a righteousness from God has been made known apart from law.” (Rom.3.21)
CARSON: Paul’s point…is that now, with the death and resurrection of Jesus, a righteousness from God has been made known apart from the law – covenant, the Law of Moses. This does not mean that such righteousness was unanticipated. Far from it: “the Law and the Prophets” (i.e., holy Scripture) had testified to it, had borne witness to it. In other words, “the righteousness of God” that has come to us through Jesus appeared independently from the law – covenant, but nevertheless the old law — indeed, the entire Hebrew Bible — bore witness to it and anticipated it.
