When I was still "in" a few years back (shortly before my complete mental and physical departure), I had the overwhelming conviction that I had the heavenly calling (to be with Christ) but I never partook, caving into pressure from my JW spouse and her family.
I still feel a "calling" of sorts, though I'm not sure what to call that calling. My concept of "heaven" - if it could even be considered a "concept" at this stage - certainly does not match any orthodox Christian understanding of such, so far as I'm able to discern.
