Calvin on the Three Uses of the Law

[GHansen]

7. Thus the Law is a kind of mirror. As in a mirror we discover any stains upon our face, so in the Law we behold, first, our impotence; then, in consequence of it, our iniquity; and, finally, the curse, as the consequence of both. He who has no power of following righteousness is necessarily plunged in the mire of iniquity, and this iniquity is immediately followed by the curse. Accordingly, the greater the transgression of which the Law convicts us, the severer the judgment to which we are exposed. To this effect is the Apostle’s declaration, that “by the law is the knowledge of sin,” (Rom. 3:20). By these words, he only points out the first office of the Law as experienced by sinners not yet regenerated. In conformity to this, it is said, “the law entered that the offence might abound;” and, accordingly, that it is “the ministration of death;” that it “worketh wrath” and kills (Rom. 5:20; 2 Cor. 3:7; Rom. 4:15).

 

10. The second office of the Law is, by means of its fearful denunciations and the consequent dread of punishment, to curb those who, unless forced, have no regard for rectitude and justice. Such persons are curbed not because their mind is inwardly moved and affected, but because, as if a bridle were laid upon them, they refrain their hands from external acts, and internally check the depravity which would otherwise petulantly burst forth. It is true, they are not on this account either better or more righteous in the sight of God. For although restrained by terror or shame, they dare not proceed to what their mind has conceived, nor give full license to their raging lust, their heart is by no means trained to fear and obedience. Nay, the more they restrain themselves, the more they are inflamed, the more they rage and boil, prepared for any act or outbreak whatsoever were it not for the terror of the law. And 308 not only so, but they thoroughly detest the law itself, and execrate the Lawgiver; so that if they could, they would most willingly annihilate him, because they cannot bear either his ordering what is right, or his avenging the despisers of his Majesty.

 

12. The third use of the Law (being also the principal use, and more closely connected with its proper end) has respect to believers in whose hearts the Spirit of God already flourishes and reigns. For although the Law is written and engraven on their hearts by the finger of God, that is, although they are so influenced and actuated by the Spirit, that they desire to obey God, there are two ways in which they still profit in the Law. For it is the best instrument for enabling them daily to learn with greater truth and certainty what that will of the Lord is which they aspire to follow, and to confirm them in this knowledge; just as a servant who desires with all his soul to approve himself to his master, must still observe, and be careful to ascertain his master’s dispositions, that he may comport himself in accommodation to them. Let none of us deem ourselves exempt from this necessity, for none have as yet attained to such a degree of wisdom, as that they may not, by the daily instruction of the Law, advance to a purer knowledge of the Divine will. Then, because we need not doctrine merely, but exhortation also, the servant of God will derive this further advantage from the Law: by frequently meditating upon it, he will be excited to obedience, and confirmed in it, and so drawn away from the slippery paths of sin.
