To love God is basic to man's purpose for living. But finite man, with all his deficiencies and incapacity for understanding the mysteries of the infinite, too often resigns himself to the expediency of lip-service in the direction of fulfilling that obligation to the Creator. Dom Lefebvre offers all who would perfect themselves a clear exposition of ways and means for achievement of this objective. In the process, the author includes generous quotations from the accomplished masters of the spiritual life -- St. Teresa of Avila and St. John of the Cross -- to document his recommendations. These in themselves serve as a timely commentary for moderns on the practicality of the views of these great mystics. The author's forthright style suggests a direct communication with the Lord, particularly when he says categorically, for example, ""God wants"", or ""God demands"". But coming from a serious student of the subject, who substantiates his positions with quotations from the best sources, this tendency of spiritual writers is easily overlooked. Dom does not confine himself to platitudinous phrases. He supplies a practical compendium of suggestions for personal application that will be of great help to Christians serious about complete fulfillment of divine love which seeks out man but demands of his sincerity, patience, simplicity, trust and suffering for its realization.
