Saint Louis de Montfort says that by practicing his method of True Devotion to Mary, you will give more glory to Jesus in a month than in many years of a more demanding devotion.
“Here are my reasons for saying this:
(1) Since you do everything through the Blessed Virgin as required by this devotion, you naturally lay aside your own intentions no matter how good they appear to you. You abandon yourself to our Lady's intentions even though you do not know what they are. Thus you share in the high quality of her intentions, which are so pure that she gave more glory to God by the smallest of her actions, say, twirling her distaff, or making a stitch, than did St. Laurence suffering his cruel martyrdom on the grid-iron, and even more than all the saints together in all their most heroic deeds!
Mary amassed such a multitude of merits and graces during her sojourn on earth that it would be easier to count the stars in heaven, the drops of water in the ocean or the sands of the sea-shore than count her merits and graces. She thus gave more glory to God than all the angels and saints have given or will ever give him. Mary, wonder of God, when souls abandon themselves to you, you cannot but work wonders in them!
(2) In this devotion we set no store on our own thoughts and actions but are content to rely on Mary's dispositions when approaching and even speaking to Jesus. We then act with far greater humility than others who imperceptibly rely on their own dispositions and are self- satisfied about them; and consequently we give greater glory to God, for perfect glory is given to him only by the lowly and humble of heart.
(3) Our Blessed Lady, in her immense love for us, is eager to receive into her virginal hands the gift of our actions, imparting to them a marvelous beauty and splendor, and presenting them herself to Jesus most willingly. More glory is given to our Lord in this way than when we make our offering with our own guilty hands.
(4) Lastly, you never think of Mary without Mary thinking of God for you. You never praise or honor Mary without Mary joining you in praising and honoring God. Mary is entirely relative to God. Indeed I would say that she was relative only to God, because she exists uniquely in reference to him.
She is an echo of God, speaking and repeating only God. If you say "Mary" she says "God". When St. Elizabeth praised Mary calling her blessed because she had believed, Mary, the faithful echo of God, responded with her canticle, "My soul glorifies the Lord." What Mary did on that day, she does every day. When we praise her, when we love and honor her, when we present anything to her, then God is praised, honored and loved and receives our gift through Mary and in Mary.
