Agree with 1/4 of what you posted.
- The prophecy in the book of Revelation is for the Jesus followers - whether of Jewish or gentile heritage.
- Chapter 2 and 3 are to churches that are varied from mixed to mostly gentile.
- Chapters 5 to 20 are about the fall of Jerusalem in 70 AD - and we read about not only the 144K Judeans but also the vast multitudes from all nations who are included in the worship of the Lord.
- By the time John wrote the book of Revelation *around 65 AD*, “Christianity” was still a sect of 2nd temple judaism.
- Current day Judaism is derived from Phariseeism and actually dates to AFTER 70 AD, so is a “niece” religion to Christianity and about 40 odd years YOUNGER
