THE DIARY OF SAINT MARIA FAUSTINA. The Polish nun who lived a cloistered and contemplative life is now known throughout the world as "The Apostle of the Divine Mercy." In her Diary, Sister Faustina reveals her intimate and mystical union with God, and now when we gaze on the Image of the Risen Christ with Blood and Water flowing from His side, we bow our heads and say together, "Jesus, I Trust in You."
