"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. This is what Paul says, Romans 4:15: 'The Law worketh wrath.' And Romans 5:20: Sin is increased by the Law. [The Law entered that the offense might abound.']

"Contrition is altogether necessary in those who truly and earnestly repent. For there can be no true repentance in those who, persuaded of their own holiness, dream that they are without sin, or who disregard, minimize, excuse, cloak, and defend their sins, despise or ridicule the divine threats, do not care about the wrath of God, are not moved by His judgment and displeasure, and therefore persevere and continue in sins against their conscience, delight in sins, and seek and seize occasions for sinning and for whatever they intentionally heap up without the fear of God--in them, I say, there can be no true repentance...."
