A few words to the doves about the post that there is a 7 year tribulation. In general be wary of long winded explanations to prove specific points in scripture.
Is there a 7 year tribulation? I'm not aware of one in scripture. I do know from the book of Daniel that there is the prophesy of the 70 weeks, each week consisting of 7 years. 69 of those weeks have been fulfilled, the remaining week of 7 years yet remains to be fulfilled. I also know from the book of Daniel that in the midst of that final week the person commonly referred to as the Antichrist will declate himself to be God in the rebuilt temple in Jerusalem. I also know from the book of Matthew that immediately after that event there will be great tribulation such as the world has never seen. A little putting together of Daniel and Revelation leads most bible students to agree this terrible event know as the great tribulation lasts 3 1/2 years.
Is all of Daniel's 70th week "the seven year tribulation"? Only if you want it to be. I have books that say it is. One book I have takes two hundred pages to make that point. But men can justify anything. Just look at history.
