Estius: rousing grace actually wakes the sinner
Thesis XL. By rousing grace, then, they mean the grace by which a sinner, or one who has stopped doing good and lies as if sunk in a kind of sleep, is given the thought, desire and will to do a good work, in such a way that he can now be said to be truly roused from the sleep of sin or from neglect of good works.
By assisting grace they mean the grace by which someone already roused is helped to will more perfectly what he has begun to will, and to carry out what he has already willed.
'Grace,' they say, 'rouses us to will and assists us to do. Willing belongs to rousing grace; doing and completing belong to assisting grace.' This is the interpretation of William Estius on book 2 of the Sentences, distinction 26, paragraph 11.
Latin
XL. Igitur per gratiam excitantem intelligunt illam qua homini peccatori, aut a bono opere cessanti, & tanquam quodam sopore depresso, ita immittitur cogitatio, desiderium, & voluntas boni operis, ut jam vere excitatus a somno peccati, aut negligentiae bonorum operum dici possit. Gratiam vero adjuvantem vocant illam qua is qui jam est excitatus adjuvatur, ut perfectius velit quod jam velle incepit: utque perficiat quod jam voluit. Excitat enim, inquiunt, gratia ut velimus, adjuvat ut faciamus. Excitantis gratiae est velle; adjuvantis facere atque perficere. Quae interpretatio est Gulielmi Estii in lib. 2. sentent. distinct. 26. paragr. undecimo.
