The merits of our Lord’s Cross and Resurrection have infinite value before the Father, and that for all time and eternity. These merits are never diminished, much as they are graciously poured out upon all souls. (See: Catechism of Catholic Church, 1476-1477)

We have access to Christ’s infinite merits through the gift of faith, through the Sacraments, and through the gift of prayer.

Our Lord Jesus also chose to open the floodgates, to pour out His infinite merits, His Divine Mercy, especially at three o’clock, the holy hour of His sacred death on the Cross:

“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. I will allow you to enter into My mortal sorrow. In this hour, I will refuse nothing to the soul that makes a request of Me in virtue of My Passion.” (Diary of St Faustina, 1320)

There is nothing that the soul cannot obtain from our Lord Jesus when it comes to Him with confidence and trust in His infinite goodness and mercy.

Prayer:

Lord Jesus, in virtue of the infinite love with which you opened your arms upon the Cross and suffered death in order to give us life, in virtue of your Divine Mercy, deliver us from our miseries.

Drive away the dangers that threaten our lives and salvation, cover us in your precious Blood, do not put us to the test, lead us not into temptation, fill us with true and perfect contrition for our sins, with the spirit of reconciliation, with the spirit of prayer, with the deepest love of your Sacred Passion, restore us to your friendship, and grant us your Holy Spirit evermore.

(You can say this prayer at the start of the Divine Mercy Chaplet, if you like)
