yes and no.
yes because i believe it exists, and no because it wouldnt be heaven to me.
in heaven you are given eternal life. that is something i couldnt handle. knowing there is no end is something that would cause much pain to me.
i would rather no longer exist after death. life is great because it is short and will end.
eternal life would be terrible, there would be no goals. no reason to go on. i couldnt stand it. heaven would bee hell to me. even if i do good and am gratned to go to heaven, it would still be a hell for me. unlesss god lets me to no longer exist after death, which i doubt.
