Every morning I open the back door and let my dog outside and every morning he's acts like it's the first time he's ever been out there. He explores every inch of it with all the gusto he can muster. To me, in order for everlasting life to be bearable, there would have to be some kind of shift in how one experiences time, and there would have to be a change in ones memory and attention span as well. My dog remembers things when he see's them but I'm sure he doesn't think about anything specifically unless it's right in front of him. He lives in the absolute moment, doesn't plan ahead or think about the past. I think we'd have to be like that to some degree. Kids are sort of like that in that they don't have a complete concept of time or of the future. Back when I believed in the Adam and Eve story, I used to think that maybe part of the innocence they lost when they sinned, was the childlike concept of time.
Growing up as a JW I was force fed the notion that I wasn't even going to graduate highschool before the New System arrived let alone get old enough to die from old age. I don't think I'd have expected such a thing had the adults in my life not held out everlasting life as something I should want.
Now I don't really want to live forever but I don't necessarily want to die either. Good thing it's out of my hands because I wouldn't be able to decide. These days I'm trying to be more like my dog by living in the moment more and not expecting too much out of life. Now that I've quit going to those meetings where the bad in the world is the main topic and where you are encouraged to live your life in suspended animation until armageddon , I find that I'm much more content and less aprehensive about the future.
