Again, let’s not go further than scripture says.
You stated “of course the rapture generation won’t die”.
The scripture does not say that.
It says we will be “caught up” in the air with the Lord.
Don’t we know we will get new bodies that are incorruptible?
Why do you want to drag the old one around if you are raptured?
The popular idea of people “disappearing” - where is that in scripture? What if we suddenly went OUT of our bodies and into our new celestial bodies and were with the Lord in the twinkling of an eye?
I don’t know about you, but I am ready for my new body. What happens with the old one? Well it probably won’t blink out of existence.
