Then I find this in St. Alphonsus de Ligouri’s “Preparation for Death”
“The physician,” says St. Augustine, “knows better than the patient what is useful to him”(1). The holy doctor adds, that God refuses to some through mercy, what he gives to others through wrath.(2) Hence we should ask temporal blessings only on condition that they will be profitable to the soul. But spiritual graces, such as pardon of sins, perseverance, divine love, and the like, should be asked absolutely, and with a firm confidence of obtaining them.
