“Have the general resurrection and great judgment happened?”
They obviously haven’t happened, since, as I said, us living Christians are all still here, walking around in our same old bodies, and we are not reigning over anything. So if we were to try and interpret it your way, it would make God a liar.
That’s the consequence of a method like preterism, where you determine what you want to believe first, and then try to interpret the text in light of that goal. It just leads to absurdities and contradictions.
Boogieman, I believe you have an idea about resurrection that is based more on assumption than exegesis. It was to be a rising out of hades to heaven by the faithful, an event that was not visible. As I pointed out in a comment above, the passages about resurrection and judgment are consistently portrayed in Scripture as imminent to the biblical writers.
