First: sufficient grace suffices for actual conversion
Thesis CXVII. First, they hold with Molina that a sufficient grace is given for a person's salvation and conversion. Even if he is not actually converted, he can still be actually converted through it, if he chooses to use it, without any further prior aid from God. A grace that needs some other preceding aid of God before the good action really follows is not, in their view, properly called sufficient.
Latin
CXVII. Primo enim cum Molina existimant dari quandam gratiam sufficientem, ad hominis salutem & conversionem, per quam, licet homo actu non convertatur, potest tamen, si voluerit illa uti, actu converti, sine ullo alio praevio Dei auxilio. Nec putant eam gratiam sufficientem recte dici, praeter quam aliud Dei auxilium ad bonam actionem praecedaneum requiritur, ut actio reapse sequatur.
