Cap. III Sol. Rat. 13 close: no despair for the willing — removes boasting, not study of holiness
Nor do we cast despair on any mortal willing to believe and live piously: we give such people most sure confidence they belong among the elect and those to be saved. We preach gratuitous election while teaching that no one gets fruit or comfort from it without faith and holiness — and that anyone living faithfully and holily can and ought to count himself among the elect. So the doctrine takes away every occasion of boasting and pride in one's works, but not the study of doing well; it rather kindles that study, teaching that no one has any certainty of election outside pursuit of holiness, or can ever reach election's end — eternal life — except by the way of holiness.
Latin
Neque ulli mortalium volenti credere et pie vivere desperationem injicimus, sed certissimam fiduciam talibus praebemus, eos pertinere ad numerum electorum et salvandorum. Nam sic praedicamus gratuitam electionem, ut simul doceamus neminem posse vel fructum vel solatium inde percipere absque fide et sanctitate: quemlibet autem fideliter et sancte viventem posse ac debere seipsum in electis numerare. Haec igitur doctrina electionis tollit homini omnem gloriandi et superbiendi de suis operibus occasionem, sed non tollit ipsum studium bene operandi; quin excitat potius, dum docet, neminem aut certitudinem ullam habere de sua electione extra studium sanctitatis, aut unquam ad finem electionis, id est, vitam aeternam, pervenire posse nisi per viam sanctitatis.
