Anecdotal data doesn't really count. It's what we see in society as a whole that matters. And what we see is that Christians don't actually act as if they believe Heaven (and hell, for that matter) exist. They say they believe it, but they act as if they don't.
I, for one, am very glad that this apparent “contradiction” occurs. If my “believing” family members were full of joy that my brother was getting his “mansion” when he died (nearly two years ago after a short battle with cancer), I would have been livid.
Then, too, the query itself is a bit tricksy:
The OP fully understands that we’re little more than psychotic apes with brains too big for our own good.
Asking how a religion, even, if
true, (assume for the sake of argument that Christianity is “the right religion” and that the decedent now exists on a high plane of existence loaded with unbound
joy), could
negate millions of years of evolutionary pressure (as well as thousands of years of social-norms).
Emotions are there for a reason.
That reason isn’t to assert what you think to be true but to acknowledge what one feels is what one feels.
I usually go numb for a few weeks and slowly grieve over time. I got family that get the bulk out as soon as they can, that’s what works for them, great.
I like to savor the
pain. In small doses, for years.
I don’t ever pray for my family, the 400 people who I know to “be family”, but I sure do think of nearly half of them pretty regular.
Having “one go missing”, for me, requires “work”, to look up their birthday, and think of the birthday parties we may have shared at being, remembering interactions and what they said, and how they talked and how much, in that moment you realized that you “shared blood” with this guy and you were
glad!
Expecting
Homo sapiens to believe their way into expressing joy when losing a loved one, would be
pushing it, even for their God.
