Notwithstanding the fact that, according to the above exposition in the Commentary on Romans, man has absolutely no freedom of choice for doing what is good and that we cannot know with regard to our works how God will account them, Luther frequently speaks in the same book of the preparation necessary for obtaining justification, namely, by works. Here his feeling and his eloquence come into full play at the expense of clear theology. He does not even take into account the irresistibility of grace, which is the point he is bound to arrive at finally. Christ alone does the work, he says (“_soli Christo iustitia relinquitur, soli ipsi opera gratiæ et spiritus_”).[531] On the other hand, the bringing about of justification, at least so far as preparation goes, is imposed upon man. There are “works which predispose to justification,” he teaches (“_opera quæ fiunt præparatorie ad iustificationem acquirendam_”). “Whoever by his works disposes himself for the grace of justification is already, to a certain extent, righteous; for righteousness largely consists in the will to be righteous.”[532] “Such works,” he continues, “are good, because we do not trust in them, but by them prepare ourselves for justification by which alone we may hope for righteousness.”[533] “Therefore we must pray earnestly, be zealous in good works and mortify ourselves (‘_castigandum_’) until readiness and joyousness develop in the will and its old inclination to sin is overcome by grace.” “For the grace [of justification] will not be given to man without this personal agriculture of himself” (“_non dabitur gratia sine ista agricultura sui ipsius_”).[534] We must continue to “look upon such works as merely preparatory, just as all works of righteousness performed in grace, prepare in their turn for an increase of justification, according to Apoc. xxii. 11.”[535] “Only so can we be saved, namely, by repenting that we are laden with sin and are living in sin, and by imploring of God our deliverance.[536] He also, in other passages, emphasises the fact that works are necessary for justification as its preparation: “We must do works in order to obtain justification (‘_opera pro iustificatione quærenda_’), works of grace and faith; they confirm the desire for justification and the fulfilment of the law, but we may not think that we are justified by them.” “Rather, true believers spend their whole life in seeking justification ... whoever seeks it with the heart and by works, is without doubt already justified in God’s sight.”[537] Towards the end of the Commentary he describes in emphatic words, which will be quoted below, the humility and sighing which should bring about justification.
