Lately I brought out a work on the Infancy of our Saviour, entitled Novena for Christmas; and another entitled Preparation for Death, besides the one on the Eternal Maxims, most useful for meditation and for sermons, to which are added nine discourses suitable during seasons of Divine chastisements. But I do not think that I have written a more useful work than the present, in which I speak of prayer as a necessary and certain means of obtaining salvation, and all the graces that we require for that object. If it were in my power, I would distribute a copy of it to every Catholic in the world, in order to show him the absolute necessity of prayer for salvation. I say this, because, on the one hand, I see that the absolute necessity of prayer is taught throughout the Holy Scriptures, and by all the holy Fathers; while, on the other hand, I see that Christians are very careless in their practice of this great means of salvation. And, sadder still, I see that preachers take very little care to speak of it to their flocks, and confessors to their penitents; I see, moreover, that even the spiritual books now popular do not speak sufficiently of it; for there is not a thing preachers, and confessors, and spiritual books should insist upon with more warmth and energy than prayer; not but that they teach many excellent means of keeping ourselves in the grace of God, such as avoiding the occasions of sin, frequenting the sacraments, resisting temptations, hearing the Word of God, meditating on the eternal truths, and other means, all of them, I admit, most useful; but, I say, what profit is there in sermons, meditations, and all the other means pointed out by masters of the spiritual life, if we forget to pray? Since our Lord has declared that he will grant his graces to no one who does not pray. "Ask and ye shall receive." (John 16:24)
