John Wesley 
The Law Established Through Faith [EPUB ebook] 
Two Discourses

St. Paul, having the beginning of this Epistle laid down his general proposition, namely, that “the gospel of Christ is the power of God unto salvation to every one that believeth;”—the powerful means, whereby God makes every believer a partaker of present and eternal salvation;—goes on to show, that there is no other way under heaven whereby men can be saved. He speaks particularly of salvation from the guilt of sin, which he commonly terms justification. And that all men stood in need of this, that none could plead their own innocence, he proves at large by various arguments, addressed to the Jews as well as the Heathens. Hence he infers, (in the 19th verse of this chapter, ) “that every mouth, ” whether of Jew or Heathen, must be “stopped” from excusing or justifying himself, “and all the world become guilty before God.” “Therefore, ” saith he, by his own obedience, “by the words of the law, shall no flesh be justified in his sight.” “But now the righteousness of God without the law, ”—without our previous obedience thereto, —“is manifested;” “even the righteousness of God, which is by faith of Jesus Christ, unto all and upon all that believe:” “For there is no difference, ”—as to their need of justification, or the manner wherein they attain it;—“for all have sinned, and come short of the glory of God;—“the glorious image of God wherein they were created: And all (who attain) “are justified freely by his grace, through the redemption that is in Jesus Christ, whom God hath set forth to be a propitiation through faith in his blood; that he might be just, and yet the justifier of him which believeth in Jesus;—“that without any impeachment to his justice, he might show him mercy for the sake of that propitiation. “Therefore we conclude, ” (which was the grand position he had undertaken to establish, ) “that a man is justified by faith, without the works of the law.” (Verses 20–28.)
