I certainly have heard that before; and unless I'm mistaken, it refers to
greedy and vain cowards (such as yourself) who want "heaven" to be a place
on Earth and who obviously want to
live forever on Earth, in order to
continue enjoying their sinful pleasures (mainly greed and vanity, followed by lust and gluttony)!

Furthermore, whenever they (including you) are
no longer able to continue enjoying their sinful pleasures, they
end up committing the sins of
anger (which
might lead to
murder) or
despair (which
might lead to
suicide).
