I HAVE already published several spiritual works, viz.: Visits to the blessed Sacrament, the Clock of the Passion of Jesus Christ, the Glories of Mary, a volume containing a Refutation of Materialism and Deism, and several small Treatises of Devotion, a Novena of the Nativity, which treats of the infancy of our Lord, a Book on the eternal maxims, entitled, a Preparation for Death, which contains a great deal of useful matter, for Sermons and Meditations, and also nine Discourses for the time of public calamities. But of all these works, I do not consider one more useful than this little book which treats of prayer as a secure and necessary means of obtaining salvation and all the graces necessary for it. Were it in my power, I would publish as many copies of this little work, as there are Christians on earth, and would give to each a copy, that each might be convinced of the absolute necessity of prayer for salvation. ~ St. Alphonsus 101 pages
