Such is the theme of the retreat for members and volunteers of the Faustinum Association as well as for Divine Mercy devotees to be held on January 12-14, 2024 at the Shrine of Divine Mercy in Krakow-Łagiewniki. Every one of us christened people is called to give witness of the merciful love of God. This is not an easy task, especially in our closest surroundings, which are often openly indifferent or even hostile to God and the Church. How to be a witness of Mercy in the modern world, based on the Bible and the experience of St. Faustina will be the topic of the retreat provided by Fr. Zbigniew Pałys, M.S., a teacher at the seminary of La Salette fathers and Sr. Maria Faustyna Ciborowska, I.S.M.M., Doctor of Bible Studies involved in the proclamation of the message of Mercy.
