I think that it is wrong to hold (with the Premillennialists) that, from chapter 4:1 on, Revelation is all future.
Question: Do you believe the Bible teaches a pre-tribulation rapture? Will the believers in Christ be taken out of this world while the unbelievers are "left behind" to endure the final tribulations before the last day of this world? And will those unbelievers "left behind" have a last chance to repent?

Answer:
The answer is "No" to all questions...
BTW I note on the OPC you provided that there’s an author speaking in the first tense..as if this is his opinion rather than fully the doctrine the Opc has. So is this guy that significant to write as he does,...is it just his opinion?
