"We died with willful resolve to be separated from God. Do you now understand why hell lasts forever? It is because our wills were fixed for eternity at the moment of death. We had made our final choice. Our obstinacy will never leave us.
"Under compulsion, I must add that God is merciful even towards us. I affirm many things against my will and must choke the torrent of abuses I should like to vomit out.
“God was merciful to us by not allowing our wicked wills to exhaust themselves on earth as we should have been prepared to do. This would have increased our faults and our pains. He caused us to die before our time, as in my case, or had other mitigating circumstances intervene. Now He shows Himself merciful towards us by not compelling a closer approach than that afforded in this remote inferno. Every step bringing us closer to God would cause us a greater pain than that which a step closer to a burning furnace would cause you."
"I tell you, the fire of which the Bible speaks does not mean the torment of the conscience. Fire is fire! What He said: ‘Away from Me, you accursed ones, into eternal fire’, is to be understood literally. Literally! How can the spirit be touched by material fire, you will ask? How can your soul suffer on earth when you put your finger on the flame? In fact the soul does not burn; and yet what torture all the individual feels!
"Our greatest torture consists in the certain knowledge that we shall never see God. How can this torture us so much, since on earth we are so indifferent? As long as the knife lies on the table it leaves you cold. You see how keen it is, but you do not feel it. Plunge the knife into the flesh and you will start screaming in pain. Now we feel the loss of God; before we only thought of it.
"Not all the souls suffer to the same degree. With how greater wickedness and how more systematically one has sinned, the more weighs on him the loss of God and the more the creature he abused is choking him. The lost Catholics suffer more than those of other religions, because they, mostly, received and despised more graces and more light. He who knew more suffers more cruelly than he who knew less. He who sinned out of malice suffers more keenly than he who sinned out of weakness. But nobody suffers more than he deserves. Oh, if that were not true, I should have a motive to hate!"
