There’s going to be an end of the world, when Jesus returns. I don’t know enough about it to know whether everyone still alive on earth will die before they can be judged. Will they all die? If so, then their age, whether it’s 10, 100 or 1000 years, makes no difference. Will they not die but just be immediately judged? Then again, it would have been in God’s plan all along that the people alive at the end of the world wouldn’t die, and again their age is irrelevant.
Seems to me that the issue is not avoiding death per se, but avoiding final judgement.
I reckon some people fear death because they don’t believe in an afterlife and therefore don’t want life to be over. But probably others are scared of death because they know deep down inside that there is an afterlife, and that with the kind of life they’re living, they’re not going to go to Heaven.
One of the saddest things I heard about was a priest who met a young man who refused to believe he would die. He kept insisting that, no, scientists were working on a cure for death, and they were going to find one, and he would live forever. This young man was absolutely adamant about this, no matter how much the priest tried to reason with him that he couldn’t live forever. I wonder how many people today are also living like this, unable to accept their own mortality.
