It is written in the prophet, Jer. 31, 33: I will put My Law in their inward parts, and write it in their hearts. And in Rom. 3, 31 Paul says: Do we, then, make void the Law through faith? God forbid! Yea, we establish the Law. And Christ says, Matt. 19, 17: If thou wilt enter into life, keep the commandments. Likewise, 1 Cor. 13, 3: If I have not charity, it profiteth me nothing. These and similar sentences testify that the Law ought to be begun in us, and be kept by us more and more [that we are to keep the Law when we have been justified by faith, and thus increase more and more in the Spirit]. Moreover, we speak not of ceremonies, but of that Law which gives commandment concerning the movements of the heart, namely, the _Decalog_. Because, indeed, faith brings the Holy Ghost, and produces in hearts a new life, it is necessary that it should produce spiritual movements in hearts. And what these movements are, the prophet, Jer. 31, 33, shows, when he says: I will put My Law into their inward parts, and write it in their hearts. Therefore, when we have been justified by faith and regenerated, we begin to fear and love God, to pray to Him, to expect from Him aid, to give thanks and praise Him and to obey Him in afflictions. We begin also to love our neighbors, because our hearts have spiritual and holy movements [there is now, through the Spirit of Christ a new heart mind, and spirit within]. These things cannot occur until we have been justified by faith, and, regenerated, we receive the Holy Ghost: first, because the Law cannot be kept without [the knowledge of] Christ; and likewise the Law cannot be kept without the Holy Ghost. But the Holy Ghost is received by faith, according to the declaration of Paul, Gal. 3, 14: That we might receive the promise of the Spirit through faith. Then, too, how can the human heart love God while it knows that He is terribly angry, and is oppressing us with temporal and perpetual calamities? But the Law always accuses us, always shows that God is angry. [Therefore, what the scholastics say of the love of God is a dream.] God therefore is not loved until we apprehend mercy by faith. Not until then does He become a lovable object.
