It’s my personal belief that man will cross the red line one day with all this human cloning stuff and that is when the end of the world will be.
In a lot of ways, the punishment of man’s sin is found in the sin itself. i.e., I don’t think there’s one single line in the sand that will precipitate the end. But the continuing dehumanization and collateralization of life will lead to greater and greater acts of inhumanity and atrocity as societal “norms”.
Some may argue that the 20th century may never be paralleled in the kind of worldwide savagery that spanned two world wars, the concentration camps, the gulags, S.E. Asia, Africa, etc. But those were all atrocities committed during war, power consolidation, and general upheaval. We’re talking about normal, “civilized” society with a scoreboard of aborted babies that would make your run of the mill political tyrant blush. When Hitler experimented on human beings, it was ghastly. When society demands it today, it’s “progress”. That’s the qualitative difference: The 20th century featured perverted, heartless individuals; today we have a perverted, heartless society. That’s the price of sin, and God doesn’t have to lift a finger for us to suffer unspeakable punishment.
