Man, after the fall, abides under the covenant of works; and to this day, life is promised him under condition of works done by strength and nature. But if he will not do so well, death and the everlasting curse of God is denounced against him, so long as he is without Christ and without the gospel. And being freed from the covenant of works…he is admitted to the covenant of grace…. Christ, therefore, our Mediator, subjected himself to the covenant of works, and unto the law for our sake, and did both fulfill the condition of the covenant of works in his holy and good life…and also did undergo that curse with which man was threatened in the covenant of works, if that condition of good and holy works were not kept…Wherefore we see Christ in two respects, to wit, in doing and suffering, subject to the covenant of works, and in both respects he has most perfectly fulfilled it, and that for our sake whose Mediator he is become.

—Robert Rollock, Select Works, 1.52.
