of our prayer. Of these there are three classes. To the first class belong those cases in which a person needs divine help at the present moment or at least at a time definitely near, and seeks it through prayer. Such a petition would be, for instance, to obtain the necessary and effective aid of divine grace for overcoming an existing transient temptation, or the conversion of a certain sinner approaching death. To the second class belongs the avoidance of temporal evils, or of continuous temptations, or the conversion of a certain sinner now in good health. To the third class belong such benefits which can be granted only for a later period, perhaps at the hour of death. The grace of final perseverance is the foremost among these.
Having stated the preliminary conditions, the answer to the question of perseverance in prayer is:
a. Inasmuch as our prayer is directed toward the attainment of benefits of the first class, that is, of graces which we need immediately, perseverance can obviously not be an essential condition of our prayer. Either we can not attain our object by prayer, or a transient prayer which has the other necessary qualities must suffice for its attainment. The first supposition is contrary to the divine promises; therefore the alternative must stand.
