St. Louis de Montfort
“Moreover, this devotion is a practice of great humility, which God loves above all the other virtues. A soul which exalts itself abases God; a soul which abases itself exalts God. God resists the proud, and gives His grace to the humble. If you abase yourself, thinking yourself unworthy to appear before Him and to draw nigh to Him, He descends, and lowers Himself to come to you, to take pleasure in you, and to exalt you in spite of yourself. On the contrary, when you are hardly enough to approach God without a mediator, God flies from you, and you cannot reach him. Oh, how He loves humility of heart! It is to this humility that our peculiar devotion engages us, because it teaches us never to draw nigh of ourselves to our Lord, however sweet and merciful He may be, but always to avail ourselves of the intercession of our Blessed Lady, whether it be to appear before God, or to speak to Him, or to draw near to Him, or to offer Him anything, or to unite and consecrate ourselves to Him.”
