Cap. VI Arg. 2: De bono persever. — this grace prevents faith, will, and all our obedience
In a word, as Augustine best puts it (On the Gift of Perseverance, ch. 15): this grace goes before faith, before the will, before all our obedience — and works all these in the one to whom it is given and whom it thus goes before. Add what adversaries will not dare deny: God gives such grace with the intention that it produce all these in the elect and those called according to purpose.
Latin
Uno verbo, ut optime Augustinus, De bono persever. cap. 15. Haec gratia praevenit fidem, praevenit voluntatem, praevenit omnem obedientiam nostram; et haec omnia in eo cui datur, et cui haec omnia praevenit, operatur. Hisce omnibus ego addo, quod adversarii inficias ire non audebunt, talem gratiam dari a Deo ea intentione, ut haec omnia in electis et secundum propositum vocatis producat.
