Today I repeat these simple and straightforward words of Saint Faustina, in order to join her and all of you in adoring the inconceivable and unfathomable mystery of God’s mercy. Like Saint Faustina, we wish to proclaim that apart from the mercy of God there is no other source of hope for mankind. We desire to repeat with faith: Jesus, I trust in you!
This proclamation, this confession of trust in the all-powerful love of God, is especially needed in our own time, when mankind is experiencing bewilderment in the face of many manifestations of evil. The invocation of God’s mercy needs to rise up from the depth of hearts filled with suffering, apprehension and uncertainty, and at the same time yearning for an infallible source of hope.
-Saint John Paul II, Dedication of the Shrine of Divine Mercy, 2002
