The pre-trib rapture is a recent idea, but I don't think the rapture at the return of Christ is a recent concept. The prophet Zechariah tells of Christ's return in detail.
As you can see, prophecy is not too difficult to figure out. When people tell me about figurative fulfillments, I ask them to show me some. Those that have figurative or apocalyptic elements are rather obvious. That is, if you start reading about dragons, stars, beasts, horns and such, one knows one must look for literal elements. But when the prophets speak about things that are literal, you can pretty much bet that they're literal. Read Isaiah 53, for example. It's all about Christ as anyone who's read the New Testament can tell. The ones who don't want to find a literal fulfillment (like the Jews, who reject Christ) will mind a more mysterious angle.
As for the two prophets, Zechariah talks about two olive trees and two candlesticks, but doesn't tell us what they represent. John does, though. He tells us about the prophets and then said, "These are the two olive trees and candlesticks...." It's doubtful he would throw us another spiritual bone so that later someone could say, no the two prophets were actually two classes of missionaries that were abolished and then reinstated. By the time we're done they'll be two red ants on an ant hill somewhere in Tyre. Remember, too, it was the Beast who kills the two prophets. And as soon as the prophets ascend to heaven, the Beast is killed where he stands. So if you don't buy into the JW interpretation, well, it's just too bad for you.
But back to the rapture. Here again is Zechariah:
It's very easy to understand because it's all there. Does it strain critical thinking? Yeah, but so does the parting of the Red Sea, the virgin birth, the resurrection and the ascension. All religion does that, but I have no problems believing it. Note in the above the prophet states that the Lord my God (Christ) will come and "all the saints with thee." Saints means "holy ones" and can refer to the Jews, Israelites, early Christians and Christ's followers today. But John talks about how "every eye" would see him, including those who killed him. Is that a reference to the Jews he's with or those who were part of the Roman army and who are now in the spirit world?
Other than that, the scripture above is pretty clear cut.
If one reads Isaiah 63, it's difficult not to see this as Christ's second coming.
Clearly this is Yahweh speaking. He asks a rhetorical question, "Who is this that cometh....?" but then answers and says, " I that speak in righteousness, mighty to save. " Again, it inescapably points to the fact that Jehovah is Jesus Christ, and that Jehovah is not the Father, but the Son of the Father. If the Governing Body is looking for some "new light," that should be good for a few lumens. I mean, "And they shall look upon me whom they have pierced...." (Zech. 12) and " Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle. And his feet shall stand in that day upon the mount of Olives...." Here we see that Jehovah's feet will stand on the Mount of Olives, when it's a clear reference to Jesus. "Hello, McFly!"
But that's another topic.
Jesus ascended into heaven and two
angels appeared saying he would come
in like manner. They were on the mount
of Olives, where it's prophesied he will
return.
