This does not mean that one who has discovered Mary through a genuine devotion is exempt from crosses and sufferings. Far from it! One is tried even more than others, because Mary, as Mother of the living, gives to all her children splinters of the tree of life, which is the Cross of Jesus. But while meting out crosses to them she gives the grace to bear them with patience, and even with joy. In this way, the crosses she sends to those who trust themselves to her are rather like sweetmeats, i.e. "sweetened" crosses rather than "bitter" ones. If from time to time they do taste the bitterness of the chalice from which we must drink to become proven friends of God, the consolation and joy which their Mother sends in the wake of their sorrows creates in them a strong desire to carry even heavier and still more bitter crosses.
--St. Louis de Montfort, The Secret of Mary, 22.
