This is no tautology, but a necessary explanation of the former verse. For he shows that we are guilty through the offense of one man, in such a manner as not to be ourselves innocent. He had said before, that we are condemned; but that no one might claim for himself innocence, he also subjoined, that every one is condemned because he is a sinner. And then, as he declares that we are made righteous through the obedience of Christ, we hence conclude that Christ, in satisfying the Father, has provided a righteousness for us. It then follows, that righteousness is in Christ, and that it is to be received by us as what peculiarly belongs to him. He at the same time shows what sort of righteousness it is, by calling it obedience. And here let us especially observe what we must bring into God's presence, if we seek to be justified by works, even obedience to the law, not to this or to that part, but in every respect perfect; for when a just man falls, all his former righteousness will not be remembered. We may also hence learn, how false are the schemes which they take to pacify God, who of themselves devise what they obtrude on him. For then only we truly worship him when we follow what he has commanded us, and render obedience to his word. Away then with those who confidently lay claim to the righteousness of works, which cannot otherwise exist than when there is a full and complete observance of the law; and it is certain that this is nowhere to be found. We also learn, that they are madly foolish who vaunt before God of works invented by themselves, which he regards as the filthiest things; for obedience is better than sacrifices.
