That’s not much of an argument. There are more than 250 direct and indirect preterist time statements in the New Testament. That doesn’t include time related material such as Daniel’s 70 Week prophecy, which was expected to be wrapped up in the generation of the Apostles. It’s going to take more than just a mere assertion to prove your point.
Check Revelation 13 re: the mark of the beast - when has this occurred in history? And regarding Daniel’s 70th week, the apostles may have expected it, but it did not happen at that time.
