i have not read this (read the part above), but thinking about the unseen world is very complicated
for example
god is eternal (i hope my vocab is right), he lives for ever
he knows everything that is going to happen
now listen taking the point above in mind
after few centuries no 1 knows if humans might exist, but he will be there (watching)
after few hundred centuries, it is possible that the earth might not exist but he will be there (watching)
after few hundred millenniums, it is possible that he might not be there, but he will be there (watching)
after THOUSANDS AND THOUSANDS OF MILLENNIUMS, the universe might not be there (reverse big bang - end to universe), but he will be there again (watching)
so he will be there all the time (NO NUMBER OF CENTURIES - JUST INFINITY - NO END)
so what he will live for ever
now look at for ever
for ever, MEANS INFINITy
u cannot imagine the end till he will be there.
imagine being there for 2 years
imagine being there for 10 years
imagine being there for 100 years
imagine being there for 100 centuries
imagine being there for 10000000 BILLION centuries
but after that u cannot imagine the time, (so u will think, for how long will god be there watching)[imagine life, when there is no solar system/life/universe]
ur mind stops working at this point
by the way, my point was not about death(but about unseen world, and life after death)
