The only way to salvation is through Jesus Christ. Everybody knows Christ/God during the time in the womb. If any of them reject their salvation, be it in the womb or out of it, why should they be saved when they reject?
You have been given in the past, and are being given right now, the chance to be saved... to accept Jesus salvation, the only way to be saved. It would be unfair to everyone to save those people who don't accept Jesus salvation.
I mean, if you go to the store and buy strawberries, but some other guy goes to the store and buys peaches, should you get the peach flavor when you eat the strawberries? Wouldn't it be way more logical for you to get what you asked-for/purchased/ate, the strawberry flavor?
Your whole way of thinking doesn't fit with nature and physics. In other words, your personal religion doesn't fit with science.
''The only way to salvation is through Jesus Christ. Everybody knows Christ/God during the time in the womb. If any of them reject their salvation, be it in the womb or out of it, why should they be saved when they reject?'' Nothing about this is ever claimed in the bible. So, stop inventing stuff?
