After its completion in 1934, the Kazimirowski painting first hung in the Bernardine Sisters' convent near the church of St. Michael, where Sopoćko was a rector. In her diary, Faustina wrote that Jesus told her to inform her confessor that the proper place for the painting was in a church, not in the hallway of a convent. The first public exposition of the Kazimirowski painting was on 26–28 April 1935, at the Church of the Gate of Dawn in Vilnius. In 1937, on the Sunday after Easter, which later instituted as Divine Mercy Sunday by Pope John Paul II, the painting was put on display beside the main altar in St. Michael’s Church in Vilnius. The image, including small reproductions of it on various devotional materials, was used by Sopoćko in promoting devotion to the Divine Mercy.
