Whether grace is necessarily given to whoever prepares himself for it, or to whoever does what he can?

Objections

Objection 1 : It would seem that grace is necessarily given to whoever prepares himself for grace, or to whoever does what he can, because, on Rm. 5:1, "Being justified . . . by faith, let us have peace," etc. the gloss says: "God welcomes whoever flies to Him, otherwise there would be injustice with Him." But it is impossible for injustice to be with God. Therefore it is impossible for God not to welcome whoever flies to Him. Hence he receives grace of necessity.
Objection 2 : Further, Anselm says (De Casu Diaboli. iii) that the reason why God does not bestow grace on the devil, is that he did not wish, nor was he prepared, to receive it. But if the cause be removed, the effect must needs be removed also. Therefore, if anyone is willing to receive grace it is bestowed on them of necessity.
Objection 3 : Further, good is diffusive of itself, as appears from Dionysius (Div. Nom. iv). Now the good of grace is better than the good of nature. Hence, since natural forms necessarily come to disposed matter, much more does it seem that grace is necessarily bestowed on whoever prepares himself for grace.
