The reasons why so many do not obtain the effects of their prayers, are,—1st. Because they ask for what is evil; and he that makes such a request, offers the Almighty an intolerable injury by wishing to make him, as it were, the author of evil: 2nd. Although what they ask be not evil, they seek it for an evil end. (St. James iv.): 3rd. Because they who pray, are themselves wicked; (St. John ix.) for God doth not hear sinners: 4th. Because they ask with no faith, or with faith weak and wavering: (St. James i.) 5th. Because although what we ask be good in itself, yet the Almighty refuses it, in order to grant us a greater good: 6th. Because God wishes us to persevere, as he declares in the parable of the friend asking bread, Luke, ch. ii.; and that we may esteem his gifts the more: 7th. We do not always receive what we beg, because, according to St. Augustine, (lib. ii, de Serm. Dom. et epis. 34, ad Paulinum) God often does not grant us what we petition for, that he may grant us something more useful and profitable. (Maldonatus)
