1 Here we hold that the Law was given by God, first, to restrain sin by threats and the dread of punishment, and by the promise and offer of grace and benefit. But all this miscarried on account of the wickedness which sin has wrought in man.
2 For thereby a part [some] were rendered worse, those, namely, who are hostile to [hate] the Law, because it forbids what they like to do, and enjoins what they do not like to do. Therefore, wherever they can escape [if they were not restrained by] punishment, they [would] do more against the Law than before. These, then, are the rude and wicked [unbridled and secure] men, who do evil wherever they [notice that they] have the opportunity.
3 The rest become blind and arrogant [are smitten with arrogance and blindness], and [insolently] conceive the opinion that they observe and can observe the Law by their own powers, as has been said above concerning the scholastic theologians; thence come the hypocrites and [self-righteous or] false saints.
4 But the chief office or force of the Law is that it reveal original sin with all its fruits, and show man how very low his nature has fallen, and has become [fundamentally and] utterly corrupted; as the Law must tell man that he has no God nor regards [cares for] God, and worships other gods, a matter which before and without the Law he would not have believed. In this way he becomes terrified, is humbled, desponds, despairs, and anxiously desires aid, but sees no escape; he begins to be an enemy of [enraged at] God, and to murmur, etc.
5 This is what Paul says, Rom. 4:15: The Law worketh wrath. And Rom. 5:20: Sin is increased by the Law. [The Law entered that the offense might abound.]
