Jansenius: efficacious grace is a heavenly delight
Thesis LIII. Jansenius holds that the grace of Christ which, once a person has been enlightened with knowledge of the good and in various ways prompted, drawn and urged to embrace it, finally determines him effectively and surely to pursue it in fact, is nothing other than a heavenly and inexpressible sweetness, or spiritual delight. By it the will is anticipated and bent to will and do whatever God has resolved that it should will and do.
For there is no kind of good action or good will, and no effect of efficacious grace, that is not to be ascribed to this heavenly delight as to the true grace of Christ and its true cause. It is by this delight that we begin to desire the good preached to us, and by it that, with devout will, we believe and take up the good we have already thought of.
Without such a delight poured in from heaven, no prayer pleasing to God can be offered, God cannot be loved purely and chastely, the temptations of our desires cannot be resisted, and in short no good work can be done. So that doctor labours at length to prove from Augustine: De gratia Christi Salvatoris, book 4, chapters 1 and following.

LIII. Jansenius autem eam Christi gratiam, quae hominem jam boni cognitione illustratum, & variis modis pulsatum, allectum, & sollicitatum ut bonum amplectatur, ad illud tandem reapse prosequendum efficaciter & certo determinat, non aliud esse vult, quam coelestem quandam atque ineffabilem suavitatem, seu spiritualem delectationem, qua voluntas praevenitur & flectitur ad volendum faciendumque quicquid Deus eam velle & facere constituerit. Nec enim ullum esse genus actionis aut voluntatis bonae, ullumve effectum gratiae efficacis, qui non isti Coelesti delectationi, tanquam verae gratiae Christi, veraeque causae tribuendum sit. Illam esse per quam bonum, quod praedicatur nobis, incipimus concupiscere: per quam bonum jam cogitatum pia voluntate credimus atque suscipimus. Sine coelitus infusa ejusmodi delectatione, nec orationem ullam Deo gratam fundi posse, nec Deum pure & caste diligi, nec cupiditatum nostrarum tentationibus resisti, nec denique ullum bonum opus fieri. Ut prolixe Doctor ille ex Augustino probare contendit. De gratia Christi salvatoris libro 4. cap. 1. & seqq.
