The Law, Still a Rule of righteousness
Westminster Larger Catechism Q/A 95-97 – Canons of Dort Head 3 & 4, Art 5 – Inadequacy of Law For Salvation
In the same light are we to consider the law of the decalogue, delivered by God to His peculiar people, the Jews, by the hands of Moses. For though it reveals the greatness of sin, and more and more convinces man thereof, yet, as it neither points out a remedy nor imparts strength to extricate him from this misery, but, being weak through the flesh, leaves the transgressor under the curse, man cannot by this law obtain saving grace.
