300 "Oh, how much
I am hurt by a soul’s distrust! Such a soul professes that I am Holy and Just, but does not believe that I am Mercy and does not trust in My Goodness. Even the devils glorify My Justice but do not believe in My Goodness.
My Heart rejoices in this title of Mercy.
366
I desire to bestow My graces upon souls, but they do not want to accept them. You, at least, come to Me as often as possible and take these graces they do not want to accept. In this way
you will console My Heart.
367 To comfort you, let Me tell you that there are souls living in the world who love Me dearly.
I dwell In their hearts with delight. But they are few. In convents too, there are
souls that fill My Heart with joy. They bear My features; therefore the Heavenly Father looks upon them with special
pleasure. They will be a marvel to Angels and men. Their number is very small. They are a defense for the world before the justice of the Heavenly Father and a means of obtaining mercy for the world. The love and sacrifice of these souls sustain the world in existence. The infidelity of a soul specially chosen by Me
wounds My Heart most painfully. Such infidelities are swords which pierce My Heart.
512
You are my great joy; your love and your humility make Me leave the heavenly throne and unite myself with you. Love fills up the abyss that exists between My greatness and your nothingness.
580 “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.”
