Things to Come,...not historical.
“Things to Come,...not historical”
It’s both. Chapters 2 and 3 are Jesus giving His assessment of the early churches. Christians of all eras should apply his words to themselves and avoid the “lukewarmness” that disgusts Him.
The early Church was under intense persecution. The Roman Emperor Domitian (81-96) demanded that he be worshiped like a God. So did Antiochus IV Epiphanes (Daniel 7) in the Old Testament. God, working through His servant John, uses history to tell us that the end of the world will once again feature a man trying to force others to worship him as God.
