10. We have done what we were bound to do. That is, “we have brought nothing of our own, but have only done what we were bound by the law to do ” Christ speaks here of an entire observance of the law, which is nowhere to be found; for the most perfect of all men is still at a great distance from that righteousness which the law demands. The present question is not, Are we justified by works? but, Is the observance of the law meritorious of any reward from God? This latter question is answered in the negative; for God holds us for his slaves, and therefore reckons all that can proceed from us to be his just right. Nay, though it were true, that a reward is due to the observance of the law in respect of merit, it will not therefore follow that any man is justified by the merits of works; for we all fail: and not only is our obedience imperfect, but there is not a single part of it that corresponds exactly to the judgment of God.
