I have one thing I’d like to post on this subject.
Like you seem to, I believe that the greater part of souls are lost. I hope this is not the case, especially since I am a sinful person who does not pray well, but like you I do not see how to conclude otherwise given the testimonies we have.
However, it is also important to realize that even the lesser part of the whole of humanity is still a great many souls.
In one particular testimony,
Cry of a Lost Soul, a damned woman is forced to speak about Hell and the nature of her own damnation. She says this:
"Prayer is the first step towards God. And it is the decisive step. Especially prayer to her who is the Mother of Christ, whose name we never pronounce. Devotion to her rescues from the devil numberless souls whom sin would infallibly give to him."
"Numberless souls"
Similarly, there is another testimony where the visionary looks out over purgatory and saw an uncountable multitude of souls undergoing purification. (Sorry, I can’t remember who this was off the top of my head.)
My point is this. The reason that the Saints, and even Christ himself, seem to indicate that few will be saved is because so few people bother themselves with Him. So few people put in effort to stop sinning. If
you are putting in the effort, if
you are praying, and fighting to stop sinning, and trying always to grow in love of God, then
you can have a reasonable assurance of your own salvation.
And so, rather than focusing on everyone else, or the numbers, or anything like that, you need to focus on
you, and on
God.
Before anyone responds stating these words are credible yet still, we are not to despair, please look at the following: 3 (persons in purgatory) / 60000 (deaths) = .0005% or all but 1 out of every 20000 people are going to eternal fire. - derived from St. Leonard of Port Maurice quote
Also, I wanted to touch on this.
Where were all those souls coming from, and when? I think we can reasonably assume that if 20,000 monks from religious orders were to be placed in a room, or 20,000 dedicated family men, the number of the elect would be far greater than in a group of 20,000 gamblers from the streets of Las Vegas, or 20,000 atheists who cared nothing for God.
