On the second time reading through your post and prayerfully wondering what this is like compared to the world before the flood :
did Yhwh want any of the people to perish ? The Ark would not hold all the people, but could it have worked like it did in Nineveh if the people had repented in sackcloth and ashes, even though Yhwh did not offer a chance for the world to be spared as far as I know?

Then, the last thought that occurred to me as reading it, "one lost sinner" vs ninety-nine who are not lost ....
are there even one person in one hundred on earth today who is not lost ? (It seems dramatically fewer people than this are saved).

Yet the sins of all mankind are paid for by the blood of the lamb who was slain, right ? - just not efficacious for those who never believe ? Meaning EVERYONE who comes to Jesus, He will in no wise cast out,
but how many will come to Jesus ?

Or again, as the Father says - "whoever seeks Me will find Me" ; but how many will seek Him and keep seeking Him ?

Then once more it is written concerning the keys: (to the teachers?) "You have the keys of the kingdom but you refuse to enter in. And if a little one(young child? or unbeliever any age?) comes seeking the kingdom, you do all you can to prevent them from entering..." So the little ones referred to here are not in the kingdom yet, and I don't see that all, many, or some, or a few? of them will be ... Is this clarified somewhere ?
