I have gone back and looked at Daniel 9 again and Matthew 24, and it is still obvious that Jesus was putting the Tribulation into the future, a future that would be a long time from then. The signs he talked about before the “tribulation’, “spoken of by Daniel the prophet”, were to occur BEFORE the tribulation. Signs like the gospel getting preached unto all nations.
The earliest “post-apostolic” writings would not have said otherwise. PAUL himself said: “But ye, brethren, are not in darkness, that that day should overtake you as a thief.” – 1 Thessalonians 5:4
Paul made that warning because some people back then were saying “any minute” now, maybe due to the same misinterpretations of Jesus “no man knoweth”.
Isaac Newton also projected the Second Coming centuries into his future, though from what I’ve read, the basis for his calculations may be faulty. The point is it was commonly known by Biblical scholars even from before him and after him, among other things, that the Antichrist and Second Coming would NOT happen before the restoration of the nation of Israel, the return of Jews to the Promised Land.
So it is NOT true that the post-millenialist view was always in vogue. it has been around awhile but in historical terms is recent.
When Jesus said “Let no man deceive you”, he immediately clarified. Look at the two verses together:
Matthew 24:4 And Jesus answered and said unto them, Take heed that no man deceive you.
Matthew 24:5 For many shall come in my name, saying, I am Christ; and shall deceive many.
That word “for” is a conjunction that in English means why the warning. He is warning against deceit by false Christs and like in the writings the earliest church leaders wrote, against those who say Jesus is Christ but deceive many.
