That grace still reaches the effect God intended; the Saint-Amour exposition
Thesis VII. Even so, they hold that this same grace of Christ is efficacious in such a person and achieves the very effect for which it was precisely and immediately given and which God intended, namely nothing other than the stirring of a good desire that has only begun. If that desire falls short of its final and complete effect, the accomplishment of the work it was urging and stirring him toward, the fault lies with the person alone, not with God; the cause is in the human being, not in God.
Yet if God chose to give as much grace as suffices and is needed for this person to repent as he ought, rise from his sin and attain God's justifying grace, he would most surely repent, rise from sin and attain that grace. But God shows mercy to each person as he wills, as much as he wills, and where he wills. This is set out in the 'true and Catholic exposition' of the five propositions on grace included in the book titled Journal de Saint-Amour.

VII. Nec eo minus censent eam ipsam Christi gratiam in tali homine esse efficacem, & effectum illum consequi ob quem praecise & proxime data est, & qui fuit a Deo intentus, qui alius non est, scilicet, quam boni & inchoati desiderii motus. Quod autem istud desiderium caruerit ultimo & perfecto effectu operis ad quod impellebat & excitabat, hominis solius vitium esse non Dei, & in homine causam esse, non in Deo. Verum si Deus vellet tantam gratiam conferre quanta sufficit, & quanta necessaria est, ut homo iste poenitentiam agat, ut oportet, a peccato suo resurgat, & ad Dei gratiam justificantem perveniat, hominem illum certissime poenitentiam acturum, a peccato resurrecturum, & ad Dei gratiam justificantem perventurum fore. Sed Deum ut vult, quantum vult, & ubi vult, uniuscujusque misereri. Sicuti videre est in expositione vera & Catholica quinque propositionum de gratia, quae inserta est libro cui titulus, Journal de Saint Amour.
