Here again comes forth reason, our reverend mistress, seeming to be marvelously wise, but who indeed is unwise and blind, gainsaying her God, and reproving Him of lying; being furnished with her follies and feeble honor, to wit, the light of nature, free will, the strength of nature; also with the books of the heathen and the doctrines of men, contending that the works of a man not justified are good works, and not like those of Cain, yea, and so good that he that worketh them is justified by them; that God will have respect, first to the works, then to the worker. Such doctrine now bears the sway everywhere in schools, colleges, monasteries wherein no other saints than Cain was, have rule and authority. Now from this error comes another: they which attribute so much to works, and do not accordingly esteem the worker, and sound justification, go so far that they ascribe all merit and righteousness to works done before justification, making no account of faith, alleging that which James saith, that without works faith is dead. This sentence of the apostle they do not rightly understand; making but little account of faith, they always stick to works, whereby they think to merit exceedingly, and are persuaded that for their work’s sake they shall obtain the favor of God: by this means they continually disagree with God, showing themselves to be the posterity of Cain. God hath respect unto man, then unto the works of man; God alloweth the work for the sake of him that worketh, these require that for the work’s sake the worker may be crowned.
But here, perhaps, thou wilt say, what is needful to be done? By what means shall I become righteous and acceptable to God? How shall I attain to this perfect justification? Those the gospel answers, teaching that it is necessary that thou hear Christ, and repose thyself wholly on Him, denying thyself and distrusting thine own strength; by this means thou shalt be changed from Cain to Abel, and being thyself acceptable, shalt offer acceptable gifts to the Lord. It is faith that justifies thee, thou being endued therewith; the Lord remitteth all thy sins by the mediation of Christ His Son, in whom this faith believeth and trusteth. Moreover, He giveth unto such a faith His Spirit, which changes the man and makes him anew, giving him another reason and another will. Such a one worketh nothing but good works. Wherefore nothing is required unto justification but to hear Jesus Christ our Savior, and to believe in Him. Howbeit these are not the works of nature, but of grace.
