It was the period from 66-70, from the Roman response to the Jewish revolt until Jerusalem’s destruction. According to the gospels, Jesus said the ‘appointed times of the nations’ aka the ‘great tribulation’ would happen within a generation of his death, and then Jesus would return shortly after. Of course, Jesus didn’t return and Christians have been making excuses ever since, leading to nutters reinterpreting passages from Revelation to conveniently apply to ‘our time’.
Non-sequitur: first you say Jesus prophecy was fulfilled then you say Jesus failed to return. Your fallacious style.
A heavenly Messianic kingdom cannot be trampled upon. Jesus was alluding to heavenly Jerusalem. The word trampled is a literary device. It is your fallacious style to first interpret Bible prophecy and then to attempt to invalidate the Bible and your interpretation of fulfilled prophecy with it. Ergo your interpretation cancels out and becomes invalid. If the Bible is not valid, prophecy is meaningless and your interpretation is also nonsense. Whereas, we have shown consistency.
