Are you trying to say that the great tribulation has already occurred?
In short yes.
Here are the reasons:
1. Revelation 1:9 “
I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ.”
2. Rev talks about famine, war, etc. - all seen in the period of the end of Nero’s reign and the year of the 5 emperors - in Jerusalem there was actually a civil war DURING the Roman siege. They burnt each other’s granaries, leading to horrific starvation and cannibalism.
3. The siege lasted for 2.5 years / 42 months / 1260 days.
4. The early Christians all believed that this was the great tribulation.
