An Excerpt from the Diary of St. Maria Faustina Kowalska

" On a certain occasion, the Lord said to me, I am more deeply wounded by the small imperfections of chosen souls than by the sins of those living in the world. It made me very sad that chosen souls make Jesus suffer, and Jesus told me, These little imperfections are not all. I will reveal to you a secret of My Heart: what I suffer from chosen souls. Ingratitude in return for so many graces is My Heart's constant food, on the part of [such] a chosen soul. Their love is lukewarm, and My Heart cannot bear it; these souls force Me to reject them. Others distrust My goodness and have no desire to experience that sweet intimacy in their own hearts, but go in search of Me, off in the distance, and do not find Me. This distrust of My goodness hurts Me very much. If My death has not convinced you of My love, what will? Often a soul wounds Me mortally, and then no one can comfort Me. They use My graces to offend Me. There are souls who despise My graces as well as all the proofs of My love. They do not wish to hear My call, but proceed into the abyss of hell. The loss of these souls plunges Me into deadly sorrow. God though I am, I cannot help such a soul because it scorns Me; having a free will, it can spurn Me or love Me. You, who are the dispenser of My mercy, tell all the world about My goodness, and thus you will comfort My Heart." - Diary, 580
