There is a tendency to always trying to look for an end time of meaning of the book of Revelation, that people forget that it was also written to specific people going through tribulation in their own time.
I have found this article that I think will put the ever and present relevance of the book in today’s setting, and not, as said before, in some future events:
Christianity and the Imperial Cult. The context of the imperial cult in Revelation 2-3 and the growing influence of Domitian would have put Christians under pressure to either conform or face some form of persecution. While this may have not been as organized as modern preachers make it out to be, Christians would have been viewed with suspicion if they did not participate in the imperial cult.
Christianity and the Pagan world. This is especially seen with regard to the social life of Greco-Roman cities. How does a practicing Christian “fit” in pagan society? Could a Christian participate in a civic event like athletic games if those games were dedicated to a god? Could they eat food at a festival if it had been used in a sacrifice to a god?
The Church and Judaism. It is possible the church had grown far enough away from Judaism by the end of the first century that the differences were quite clear. How does a Gentile who believes Jesus is Messiah relate to a Jewish faith still looking forward to the Messiah?
Different sub-Christian Groups. These early “heretical” groups within the church disagreed over authority, which may indicate the possible influence of Docetism and antinomianism. The church needed to develop internal discipline and expel teachers not conforming to apostolic teaching or ethical expectations.
Do read the short, but thought provoking article. You can find it here.
