Helena Kowalska was born in Poland in 0915. At age 19 she devoted her life as Sister Faustina to the education of troubled young women. Soon thereafter, Jesus appeared to Sister with a message of mercy with which He wanted her to "run throughout the world".
Jesus asked Sister Faustina to be merciful herself, and through His message to encourage others to trust in Him and thus prepare the world for His coming again.
Sister Faustina's devotion to Mary, the Eucharist, and Reconciliation gave her strength to offer her sufferings to God for the Church and those in special need, especially great sinners and the dying. Sister Faustina died from tuberculosis in 1938, having taken deeply into her heart Jesus' command to "be merciful as your heavenly Father is merciful."
Pope John Paul II canonized Saint Faustina on Mercy Sunday, April 30,2000.
