Sister Faustina's mission

In the Old Covenant – said Lord Jesus to Sister Faustina – I sent prophets wielding thunderbolts to My People. Today I am sending you with My mercy to the people of the whole world  (Diary 1588)

Speak to the world about My mercy; let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice. While there is still time, let them have recourse to the fount of My mercy; let them profit from the Blood and Water which gushed forth for them (Diary 848).

The Lord Jesus did St. Sister Faustina Kowalska, apostle of Divine Mercy. Its mission is to remind the world of the eternal truth of God's merciful love for every human being. He met them and gave it does, above all through the witness of their own lives and leaving us Diary, which appears incomprehensible mercy of God, encouraging the reader to trust his goodness. Sister Faustina also invites us to beg for mercy of God for every man and for showing him in every situation of life.

I feel certain that my mission will not come to an end upon my death, but will begin. O doubting souls, I will draw aside for you the veils of heaven to convince you of God‟s goodness, so that you will no longer continue to wound with your distrust the sweetest Heart of Jesus. God is Love and Mercy (Diary 281)
