True devotion to our Lady is constant. It strengthens us in our desire to do good and prevents us from giving up our devotional practices too easily. It gives us the courage to oppose the fashions and maxims of the world, the vexations and unruly inclinations of the flesh and the temptations of the devil.
Thus a person truly devoted to our Blessed Lady is not changeable, fretful, scrupulous or timid. We do not say however that such a person never sins or that his sensible feelings of devotion never change.
When he has fallen, he stretches out his hand to his Blessed Mother and rises again.
If he loses all taste and feeling for devotion, he is not at all upset because a good and faithful servant of Mary is guided in his life by faith in Jesus and Mary, and not by feelings.
