The forms of devotion to Divine Mercy transmitted through Sister Faustina are:
Veneration of the image of Merciful Jesus;
the Feast of Mercy;
the Chaplet of Divine Mercy;
the Hour of Mercy;
the Spread of the Cult of Divine Mercy;
The Apostolate of Divine Mercy.

They are linked to special promises, which refer to everyone.
Every act of veneration of Divine Mercy must be an expression of trust and must be linked to the practice of mercy towards one's neighbor, if to the devotee of Mercy he must ensure all those benefits that Jesus has linked to such devotion.
