Without trust there is no devotion to Divine Mercy as the Lord Jesus desires. This handy booklet contains an explanation of the essence of devotion to Divine Mercy, that is, trust; as well as the consequent disposition that we should have toward our neighbor, that is, mercy. It contains selected prayers of St. Faustina and the novena. It also explains the origins, meaning, and the graces that Our Lord longs to shower upon us through the Image of the Divine Mercy, Divine Mercy Sunday, Chaplet, Hour of Mercy and Spreading the devotion to Divine Mercy. A brief yet good summary of St. Faustina's life and mission is also included.
