Divine Mercy
Jesus I trust in you.
“I promise that the soul that will venerate this image will not perish. I also promise victory over [its] enemies already here on earth, especially at the hour of death. I Myself will defend it as My own glory.” [48]
In one of the first booklets that Sister Faustina’s confessor, Father Sopocko, published, he mentioned a promise made by Jesus regarding the veneration of the Image of Himself that He told Faustina to paint, that we cannot find neither in the diary nor in her letters. Before St. Faustina was told by her spiritual director to keep a diary of her spiritual experiences, she used to record those, about which she thought she ought to inform him, on pieces of paper and give them to him. The Sister who was the vice-postulator for Poland knew that there was a collection of these which ultimately must have been given to the investigatory tribunal that was to inspect her writings, and it’s possible that this promise was mentioned among those papers. Anyway, Father Sopocko knew about it and I’m sure that if it wasn’t true, he would not have included it in that booklet. It was a promise that Jesus made: I will save those cities and houses in which this Image will be found. He also said: I will likewise protect the persons who will honor and trust in My Mercy. - Source
