Today St. Margaret Mary Alacoque shows to us the riches of God, the depth and tenderness of Divine Love. Saint Margaret has been one of those "instruments" that God has chosen to reveal to us the wonders of his merciful Love. Only three centuries have passed since those times, and the stream of devotion to the Merciful Heart of Jesus has grown to become a wide river. Other “tributaries” have joined that river (Saint Gemma Galgani, Saint Faustina Kowalska, Saint Pio de Pietrelcina…). In fact, the Church of Christ lives already immersed in a "new stage": the time of Mercy, a stage that will no longer end. The feast of the Sacred Heart of Jesus finally arrived with Saint Margaret and, thanks to the revelations to Saint Faustina, the Sunday of Divine Mercy was established.

—Those treasures can only be seen next to the Cross: «My God, I do or suffer such things in the Heart of Your Son and according to His Holy designs, and I offer them in reparation for all the bad or imperfect there is in my own works» (Saint Margaret).
