This is perhaps the greatest sermon I have ever read, and will likely ever read. I include portions of it here.
The Little Number of Those Who Are Saved, by St. Leonard.
St. Vincent Ferrer...relates that an archdeacon in Lyons gave up his charge and retreated into a desert to do penance, and that he died the same day and hour as St. Bernard. After his death, he appeared to his bishop and said to him, "Know, Monsignor, that at the very hour I passed away, 33,000 people also died. Out of this number, Bernard and myself went up to heaven without delay, three went to purgatory, and all the others fell into hell."
Our chronicles relate an even more dreadful happening. One of our Brothers, well-known for his doctrine and holiness, was preaching in Germany. He represented the ugliness of the sin of impurty so forcefully that a woman fell dead of sorrow in front of everyone. Then, coming back to life, she said, "When I was presented before the Tribunal of God, 60,000 people arrived at the same time from all parts of the world; out of that number, three were saved by going to purgatory, and all the rest were damned."
O abyss of the judgments of God! Out of 33,000, only five were saved! And out of 60,000, only three went to heaven! You sinners who are listening to me, in what category will you be numbered? What do you say? What do you think?
...
If you consider the sacrament of penance, there are so many distorted confessions, so many studied excuses, so many deceitful repentances, so many false promises, so many ineffective resolutions, so many invalid absolutions! Would you regard as valid the confession of someone who accuses himself of sins of impurity and still holds to the occasion of them? Or someone who accuses himself of obvious injustices with no intention of making any reparation whatsoever for them? Or someone who falls again into the same iniquities right after going to confession? Oh, horrible abuses of such a great sacrament!
...
Why, then, are you so surprised that the greater number goes to hell? To come to a door, you must take the road that leads there. What have you to answer such a powerful reason?
The answer, you will tell me, is that the mercy of God is great. Yes, for those who fear Him, says the Prophet; but great is His justice for the one who does not fear Hiim, and it condemns all obstinate sinners."
...
God is so good that when He sees a sinner running to his ruin, He runs after him, calls him, entreats and accompanies him even to the gates of hell; what will He not do to convert him? He sends him good inspirations and holy thoughts, and if he does not profit from them, He becomes angry and indignant, He pursues him. Will He strike him? No. He beats at the air and forgives him. But the sinner is not converted yet. God sends him a mortal illness. It is certainly all over for him. No, brothers, God heals him; the sinner becomes obstinate in evil, and God in His mercy looks for another way; He gives him another year, and when that year is over, He grants him yet another.
But if the sinner still wants to cast himself into hell in spite of all that, what does God do? Does He abandon him? No. He takes him by the hand; and while he has one foot in hell and the other outside, He still preaches to him, He implored him not to abuse His graces. Now I ask you, if that man is damned, is it not true that he is damned against the Will of God and because he wants to be damned? Come and ask me now: If God wanted to damn me, then why did He create me?
Ungrateful sinner, learn today that if you are damned, it is not God who is to blame, but you and your self-will.
...
Stop, and turn around; it is Jesus who calls you and who, with His wounds, as with so many eloquent voices, cries to you, "My son, if you are damned, you have only yourself to blame: 'Thy damnation comes from thee.' Lift up your eyes and see all the graces with which I have enriched you to insure your eternal salvation. I could have had you born in a forest in Barbary; that is what I did to many others, but I had you born in the Catholic Faith; I had you raised by such a good father, such an excellent mother, with the purest instructions and teachings. If you are damned in spite of that, whose fault will it be? Your own, My son, your own: 'Thy damnation comes from thee.'
"I could have cast you into hell after the first mortal sin you committed, without waiting for the second: I did it to so many others, but I was patient with you, I waited for you for many long years. I am still waiting for you today in penance. If you are damned in spite of all that, whose fault is it? Your own, My son, your own: "Thy damnation comes from thee." You know how many have died before your very eyes and were damned: that was a warning for you. You know how many others I set back on the right path to give you the good example. Do you remember what that excellent confessor told you? I am the one who had him say it. Did he not enjoin you to change your life, to make a good confession? I am the One who inspired him. Remember that sermon that touched your heart? I am the One who led you there. And what has happened between you and Me in the secret of your heart, ...that you can never forget.
"Those interior inspirations, that clear knowledge, that constant remorse of conscience, would you dare to deny them? All of these were so many aids of My grace, because I wanted to save you. I refused to give them to many others, and I gave them to you because I loved you tenderly. My son, My son, if I spoke to them as tenderly as I am speaking to you today, how many others souls return to the right path! And you... you turn your back on Me. Listen to what I am going to tell you, for these are My last words: You have cost Me My blood; if you want to be damned in spite of the blood I shed for you, do not blame Me, you have only yourself to accuse; and throughout all eternity, do not forget that if you are damned in spite of Me, you are damned because you want to be damned: 'Thy damnation comes from thee.' "

Brothers, I want to send all of you away comforted today. So if you ask me my sentiment on the number of those who are saved, here it is: Whether there are many or few that are saved, I say that whoever wants to be saved, will be saved; and that no one can be damned if he does not want to be. And if it is true that few are saved, it is because there are few who live well. As for the rest, compare these two opinions: the first one states that the greater number of Catholics are condemned; the second one, on the contrary, pretends that the greater number of Catholics are saved. Imagine an Angel sent by God to confirm the first opinion, coming to tell you that not only are most Catholics damned, but that of all this assembly present here, one alone will be saved. If you obey the Commandments of God, if you detest the corruption of this world, if you embrace the Cross of Jesus Christ in a spirit of penance, you will be that one alone who is saved.
