You said - "We believe in an actual, PHYSICAL resurrection, just as Jesus was, that's why the 'graves open'.  Since NOTHING is ever really 'destroyed', but only 'changed' (decay, burning, etc), all that made up that person are literally 'still out there' somewhere."  I completely agree with you.  I have gone back and forth on what the "sudden destruction" would be.  Maybe an earthquake or nuclear war, but I always come back to the supernatural destruction (or reconstruction) that would involve a physical resurrection and probably the earthquakes that would accompany it.  I don't think the people who are left behind will know what hit them.  It will be utter, unimaginable chaos and it might take a while for them to even figure out who is missing. That movie "Skyline" certainly gives me the creeps.  Especially the tag line that says, "Don't look up".  I will continue to "look up" and look forward to meeting you.
