I studied this very intensely about a dozen years back. I found that if you answer three questions with what is written, you can come to only one conclusion about the tribulation.
1 Who rises first.
2 When do they rise.
3 When is the last trumpet.
you all might find this VERY interesting...I really like this guy. There is a part 1 & 2 about ‘confusion in the cemetery’ and he spells out, via scripture what happens when we die and when we go to heaven. If any of you watch it I’d love to hear your opinion.
