As a nun, mystic, prophet, and finally a saint, Saint Faustina Kowalska lived an extraordinary life. From poor a humble Polish nun to a Christian role model, she has inspired millions. During her beatification in 1993, Pope John Paul II even declared that she was one of the greatest apostles of the Twentieth Century. Jesus used her as a voice, sending her revelations that she began to record. Though she was completely uneducated, Sister Faustina compiled notebooks with these messages that are known today as the Diary of Saint Maria Faustina Kowalska. This diary contained God’s loving message of Divine Mercy. This moving and inspirational book has become increasingly popular among Catholics today.
