Saint John Paul II

Jesus words to Saint Faustina, canonized by St. John Paul II.: 
Do not be afraid of sufferings; I am with you (151).  The more you will come to love suffering, the purer your love for Me will be (279). 

St. Faustina:  
Jesus, I thank You for the little daily crosses, for opposition to my endeavors, for the hardships of communal life, for the misinterpretation of my intentions, for humiliations at the hands of others, for the harsh way in which we are treated, for false suspicions, for poor health and loss of strength, for self-denial, for dying to myself, for lack of recognition in everything, for the upsetting of all my plans (343).
