Unrenewable Covenant of Works

The same also appears evident if we consider that the covenant made with the Israelites at Sinai could not be the covenant of works. God could not consistently, either with His own honor or with the nature of the covenant of works, renew or make again that covenant with persons who, by breaking it in the first Adam, had already subjected themselves to the penalty of it. He could, indeed, display it in its terror before condemned sinners but could not again make it with them. Neither could He renew it with the Israelites in particular without disannulling the covenant of grace made with Abraham in which He graciously promised to be a God to him and to his seed after him, for a future covenant of works made with the seed of Abraham would annul the former covenant of grace made with him as their representative.
