The mischievous Pelagians maintain that this sort of grace is not given freely by God but is to be obtained by preceding merits. I myself was once so… - Thomas Bradwardine

God gives his grace freely, in the strictest sense of the word, and without merit on the part of man. For if God did not bestow his grace in this perfectly gratuitous manner, but on account of some subordinate contingent uncertain cause, he could not possibly foresee how he should bestow his free gifts.

St. Augustine confesses that he himself had been formerly in a similar mistake. 'I was once,' says he, 'a Pelagian in my principles; I thought that faith towards God was not the gift of God, but that we procured it by our own powers, and that then, through the use of it, we obtain the gifts of God; I never supposed that the preventing grace of God was the proper cause of our faith, till my mind was struck in a particular manner by the apostle's argument and testimony: What hast thou that thou hast not received, and if thou hast received it, why dost thou glory as if thou hadst not received it?' In this whole business I follow the steps of Augustine.

O great and wonderful Lord our God, thou only light of the eyes, open, I implore thee, the eyes of my heart, and of others my fellow-creatures, that we may truly understand and contemplate thy wondrous works. And the more thoroughly we comprehend them, the more may our minds be affected in the contemplation with pious reverence and profound devotion. Who is not struck with awe in beholding thy all-powerful will completely efficacious throughout every part of the creation? It is by this same sovereign and irresistible will, that whom and when thou pleasest thou bringest low and liftest up, killest and makest alive. How intense and how unbounded is thy love to me, O Lord! whereas my love, how feeble and remiss! my gratitude, how cold and inconstant! Far be it from thee that thy love should even resemble mine; for in every kind of excellence thou art consummate. O thou who fillest heaven and earth, why fillest thou not this narrow heart? O human soul, low, abject, and miserable, whoever thou art, if thou be not fully replenished with the love of so great a good, why dost thou not open all thy doors, expand all thy folds, extend all thy capacity, that, by the sweetness of love so great, thou mayest be wholly occupied, satiated, and ravished; especially since, little as thou art, thou canst not be satisfied with the love of any good inferior to the One supreme? Speak the word, that thou mayest become my God and most enviable in mine eyes, and it shall instantly be so, without the possibility of failure. What can be more efficacious to engage the affection than preventing love? Most gracious Lord, by thy love thou hast prevented me, wretch that I am, who had no love for thee, but was at enmity with my Maker and Redeemer. I see, Lord, that it is easy to say and to write these things, but very difficult to execute them. Do thou, therefore, to whom nothing is difficult, grant that I may more easily practise these things with my heart than utter them with my lips. Open thy liberal hand, that nothing may be easier, sweeter, or more delightful to me, than to be employed in these things. Thou, who preventest thy servants with thy gracious love, whom dost thou not elevate with the hope of finding thee?
