Hour of Mercy
Jesus said to Sister Faustina: At three o’clock, implore My mercy, especially for sinners; and, if only for a brief moment, immerse yourself in My Passion, particularly in My abandonment at the moment of agony. This is the hour of great mercy for the whole world. (…) In this hour, I will refuse nothing to the soul that makes a request of me in virtue of My Passion… (Diary 1320).
The essence of the Hour of Mercy, i.e. the prayer at the moment of Jesus's dying on the cross, is the Divine Mercy adoration through the contemplation of the Saviour's Passion and entreating God's mercy for the whole world, and particularly for poor sinners; for at that moment mercy was opened wide for every soul (Diary 1572).
When we turn directly and trustfully to Jesus who is dying on the cross, we have an opportunity to entreat for all the graces, both the supernatural and worldly, certainly if what we are praying for is in accordance with his will.
The practice of the prayer at the Hour of Mercy should lead us into lively, personal and gradually deepening relationship with Jesus. It should help us to penetrate the mystery of Divine Mercy that was revealed through the Saviour's passion and death so that our human hearts could be filled with gratitude towards Jesus Christ and trust him boundlessly.
