Spreading of Devoction to the Divine Mercy
Jesus said to Sister Faustina:
Souls who spread the honor of My mercy I shield through their entire lives as a tender mother her infant, and at the hour of death I will not be a Judge for them, but the merciful Savior (Diary 1075).
All those souls who will glorify My mercy and spread its worship, encouraging others to trust in My mercy, will not experience terror at the hour of death. My mercy will shield them in that final battle… (Diary 1540).
Jesus wants us to proclaim his infinite mercy through our everyday lives. We can always do it via our attitude of trust towards Divine Mercy in each situation we encounter daily and via active love towards the others. We must tell the others about his goodness and encourage them to be trustful. And the fields that we can't reach out through our deeds nor words, can be always reached through our prayer.
Jesus addressed a promise of particular importance for the priests:
Tell My priests that hardened sinners will repent on hearing their words when they speak about My unfathomable mercy, about the compassion I have for them in My Heart. To priests who proclaim and extol My mercy, I will give wondrous power; I will anoint their words and touch the hearts of those to whom they will speak (Diary 1521).
