3.
The law, therefore, by teaching and commanding what cannot be fulfilled without grace, demonstrates to man his weakness, in order that the weakness thus proved may resort to the Saviour, by whose healing the will may be able to do what in its feebleness it found impossible. So, then, the law brings us to faith, faith obtains the Spirit in fuller measure, the Spirit sheds love abroad in us, and love fulfils the law. For this reason the law is called a "schoolmaster," 1 under whose threatenings and severity "whosoever shall call upon the name of the Lord shall be delivered." 2 But how shall they call on Him in whom they have not believed?" 3 Wherefore unto them that believe and call on Him the quickening Spirit is given, lest the letter without the Spirit should kill them. 4 But by the Holy Ghost, which is given unto us, the love of God is shed abroad in our hearts, 5 so that the words of the same apostle, "Love is the fulfilling of the law," 6 are realized. So the law is good to the man who uses it lawfully; 7 and he uses it lawfully who, understanding wherefore it was given, betakes himself, under the pressure of its threatenings, to grace, which sets him free. Whoever unthankfully despises this grace, by which the ungodly are justified, and trusts in his own strength, as if he thereby could fulfil the law, being ignorant of God's righteousness, and going about to establish his own righteousness, is not submitting himself to the righteousness of God; 8 and thus the law becomes to him not a help to pardon, but the bond fastening his guilt to him. Not that the law is evil, but because sin worketh death in such persons by that which is good. 9 For by occasion of the commandment he sins more grievously who, by the commandment, knows how evil are the sins which he commits.
