Day 256 with St. Faustina's Diary

Today's readings are from Notebook 4, numbers 1256-1261. I heard a really good homily that talked about the struggle for us to understand when innocent people suffer. I thought it would be a good thing for us to talk about because we see Sister Faustina suffering and, also, her confessor and spiritual director. Trying to get this message of Divine Mercy has caused a lot of suffering for all three of them. But...why and what does it mean?
