The Polish Mystic Faustina Kowalska was declared a saint in the presence of 200,000 people today and the first Divine Mercy Sunday was celebrated worldwide. We look at her short but spiritually intense life. How the devotion to the divine mercy has spread around the world. Finally we also look at the evil that was perpetrated a few years later, in the neighbouring parts of Poland. A Deep Darkness to contrast the luminous message of Divine Mercy.
