In 1914, Luisa writes in a letter to the now Saint, Annibale M. di Francia: “I am finally sending you this handwritten copy of The Hours of the Passion of Our Lord Jesus Christ. May it all be for His greater Glory. I have also enclosed a few pages where I describe the effects and the beautiful promises that Jesus makes to everyone who meditates these Hours of the Passion. I believe that if whoever meditates on them is a sinner, he will convert; if he is imperfect, he will become perfect; if he is holy, he will become holier; if he is tempted, he will find victory; if suffering, he will find strength, medicine, and comfort in these Hours; if weak and poor, he will find a spiritual food and a mirror in which to look at himself continually and so become beautiful and similar to Jesus, our model”.
