Go here to read the article with the above title by Dr. James Tabor. The final paragraph is as follows.
For Paul the “appointed time” of the End had drawn very near (1 Cor. 7:26, 29, 31). How near, it is difficult to say, but he wrote that in the early 50’s CE. If he, like others in the movement before 70 CE, expected the fulfillment of Daniel 11 and 12, with the “desolating sacrilege” set up in the Temple at Jerusalem, then events such as Gaius’s attempt to have his statue placed there (41 CE), and Nero’s persecution of the Christians in Rome, would have fired the apocalyptic speculations of the movement to a white hot temperature (witness Mark 13). Apparently his plans to go to Spain never worked out, due to his arrest under Nero (Rom. 15:28), so his grand hope of bringing the bulk of Israel to accept Jesus as Messiah through his Gentile mission became more and more hopeless. By AD CE it was becoming increasingly difficult to maintain any immediate hope for the “redemption of Israel.” Others would pick up the pieces in various ways, but Paul was gone and what emerged in his name, even in the short decades after 70, was the beginning of a new and very different story.
