Hell
One day, just as I had awakened, when I was putting myself in the presence of God, I was suddenly overwhelmed by despair. Complete darkness in the soul. I fought as best I could till noon...I fell to the ground, despair flooding my whole soul. I suffered terrible tortures in no way different to the torments of hell. (24)
One day, I saw two roads. One was broad, covered with sand and flowers, full of joy, music and all sorts of pleasures. People walked along it, dancing and enjoying themselves. They reached the end without realising it. And at the end of the raods there was a horrible precipice; that is the abyss of hell. The souls fell blindly into it; as they walked, so they fell. And their number was so great that it was impossible to count them. And I saw the other road, or rather, a path, for it was narrow and strewn with thorns and rocks; and the people who walked along it had tears in their eyes, and all kinds of suffering befell them. Some fell down upon the rocks, but stood up immediately and went on. At the end of the road there was a magnificent garden filled with all sorts of happiness, and all these souls entered there. At the very first instant they forgot all their sufferings. (153)

Sr. Faustina is 'transported' to Hell -
Today I was led by an Angel to the chasms of hell. It is a place of real torture; how awesomely large and extensive it is! The kinds of tortures I saw: the first torture that constitutes hell is the loss of God; the second is perpetual remorse of conscience; the third is that one's condition will never change; the fourth is the fire that will penetrate the soul without destroying it - a terrible suffering, since it is a purely spiritual fire, ....the fifth torture is continual darkness and a terrible suffocating smell, and, despite the darkness, the devils and the souls of the damned see each other and all the evil, both of others and their own; the sixth torture is the constant company of Satan; the seventh torture is horrible despair, hatred of God, vile words, curses and blasphemies. These are the tortures suffered by all the damned together, but that is not the end of the sufferings. There are special tortures destined for particular souls. These are the torments of the senses. Each soul undergoes terrible and indescribable sufferings, related to the manner in which it has sinned. There are caverns and pits of torture where one form of agony differs from another. I would have died at the very sight of these tortures if the omnipotence of God had not supported me. Let the sinner know that he will be tortured throughout all eternity, in those senses which he made use of to sin. I am writing this at the command of God, so that no soul may find an excuse by saying there is no hell, or that nobody has ever been there, and so no one can say what it is like.
 
I, Sister Faustina, by the order of God, have visited the abysses of hell so that I might tell souls about it and testify to its existence. I cannot speak about it now; but I have received a command from God to leave it in writing. The devils were full of hatred for me, but they had to obey me at the command of God. What I have written is but a pale shadow of the things I saw. But I noticed one thing: that most of the souls there are those who disbelieved that there is a hell. When I came to, I could hardly recover from the fright. How terribly souls suffer there! Consequently, I pray even more fervently for the covnersion of sinners. I incessantly plead God's mercy upon them. O my Jesus, I would rather be in agony until the end of the world, amidst the greatest sufferings, than offend You by the least sin. (741)
 
Jesus' love for souls. He wants to save sinners destined for Hell
[urge] all souls to trust in the unfathomable abyss of My mercy, because I want to save them all. On the cross, the fountain of My mercy was opened wide by the lance for all souls - no one have I excluded! (1182)
 
I experience great torments of soul when I see God offended. Today I recognised that mortal sins were being committed not far from our door. It was evening. ...When I knelt down to pray, however, the Lord allowed me to experience how a soul rejected by God suffers. It seems to me that my heart was torn to pieces, and at the same time I understood how much such a soul wounds the most merciful Heart of Jesus. The poor creature does not want to accept God's mercy. (1274)
 
The loss of each soul plunges Me into mortal sadness. You always console Me when you pray for sinners. The prayer most pleasing to Me is the prayer for the conversion of sinners. Know, My daughter, that this prayer is always heard and answered. (1397)
 
Does God condemn anyone?
When the sisters got up at eleven o'clock at night to keep vigil and welcome the New Year, I had been writhing in agony since nightfall, and this lasted until midnight. I united my sufferings with the prayers of the sisters who were keeping vigil in the chapel and atoning to God for the offences of sinners. (1451). When the clock struck twelve, my soul immersed itself more deeply in recollection, and I heard a voice in my soul: "Do not fear, My little child, you are not alone. Fight bravely, because My arm is supporting you; fight for the salvation of souls, exhorting them to trust in My mercy, as that is your task in this life and in the life to come." After these words, I received a deeper understanding of divine mercy. Only that soul who wants [to be damned] will be damned, for God condemns no one. (1452)
 
Oh, how beyond comprehension is God's mercy! But- horror -there are also souls who voluntarily and consciously reject and scorn this grace! Although a soul is at the point of death, the merciful God gives the soul that interior vivid moment, so that if the soul is willing, it has the possibility of returning to God. But sometimes, the obduracy in souls is so great that consciously they choose hell; they make useless all the prayers that other souls offer to God for them and even the efforts of God Himself..(1698)
