I used to wonder why the Lord's coming for us is in Acts (Acts 1:10–11) and the epistles (1 Corinthians 15:51–57; 1 Thessalonians 4:13–18), but not in Revelation. I think there are a few reasons for it, which we might want to discuss.
J. N. Darby differentiates prophecy (which relates to God's purpose and government on earth) from revelation to the church. From that point of view, we could say the Lord's coming for us is a matter of church truth, as opposed to prophecy (and I think Robert has made this point here before, but I can't find it now). So the Lord's coming for His saints is distinct from the Lord coming with His saints: the former is detailed in the epistles (1 Corinthians 15:51–57; 1 Thessalonians 4:13–18), the latter is in prophecy (Jude 1:14–15; Revelation 19:11ff). I think there's a good deal of merit in this view.
There's another perspective on this that I think is worth contemplating. Several years ago I was part of an assembly that went through the book of Revelation over the course of several months' reading meetings. I read through that book many, many times over the course of those meetings, and was struck that it's not truly chronological. It struck me that Revelation is laid out similarly to Hebrews, where the Lord Jesus is shown to be superior in various comparisons. So the first three chapters show the Lord as Head (and Judge) over the church, then we see Him as superior over Heaven in the next couple chapters; then as superior over the fallen world and its kingdoms; over Satan, and Babylon and the antichrist; then as Judge over the living and the dead; and finally over the new creation. I realize that's very vague.
No doubt there are a lot of consecutive events in Revelation that are specifically mentioned, and there are clues right there in the text. For example, "then I saw" is a common phrase that indicates relation in time. But my point is that there are several sections that might well run concurrently.
It's also worth mentioning that Revelation is certainly a very symbolic book. There are several things in there that are not to be taken literally: the sword coming from the Lord's mouth, for example (Revelation 1:16). I really don't think we'll see a sword in the Lord's mouth when He comes to get us, I'm sure this is a symbolic figure.
So here's one bit of wisdom we can see in the scripture: moving the Lord's coming for us into the epistles, where the language is much less symbolic makes it much easier for us to grasp. We can firmly anchor the apostolic teaching of the Lord's coming literally, physically for us in time and space because of the context of 1 Thessalonians and 1 Corinthians.
But we might also remember that not all prophecy is actually fulfilled. And before you jump down to the comments section, consider the prophet Jonah. He predicted the overthrow of Nineveh in forty days, and it didn't happen (Jonah 3:4). I don't think we fully appreciate this point: the Lord sent Jonah to Nineveh, and His word to Nineveh accomplished exactly what the Lord wanted it to accomplish. But that prophetic warning went unfulfilled, precisely because they believed it.
I have heard that exact argument used for Revelation, and it's difficult to argue against. We know that God will send prophets with the purpose that their warning will be heeded; as a result, what they warn about won't come to pass.
Now, I don't actually think that's going to happen. I do believe Revelation will play out as written. But I don't know what that will look like when it comes to pass. There is symbolic language in that book, and it can be difficult to know which features are symbolic, and which ones are literal. For example: I can believe the demonic locusts (Revelation 9:1–12) will look just like demonic locusts, I can also believe they won't really be visible at all. Remember that Elisha's servant couldn't see the angelic host around him without divine intervention (2 Kings 6:17), maybe the people afflicted by those demonic locusts won't have any sense they're there, except for the pain they inflict. I just don't know.
But the point is that the Lord's coming for us is not described in terms that invite speculation. Will the Lord come down on an actual horse (Revelation 19:11), or is that a symbolic description? I don't really know. But notice that when the apostle describes His coming to get us (as opposed to His coming with us), he uses much more concrete language.
The Lord Himself will descend with a shout (1 Thessalonians 4:16), the dead in Christ will rise (1 Thessalonians 4:16), those who are His and are still living at that time will meet them in the air (1 Thessalonians 4:17). This isn't symbolic language, and it's not in a context laden with symbolism.
So here's a thought, and I think it gets back to the point that J. N. Darby and Robert were making: we can anchor our hope on the Lord's coming for us much more dogmatically (and certainly) than we can discuss things like what Babylon, or what those demonic locusts are. We can, in a sense, disagree on how to interpret big chunks of Revelation, while agreeing on 1 Corinthians 15:51–57 and 1 Thessalonians 4:13–18.
Personally, I find Darby's view of the Revelation convincing, and there are significant differences between that and the Scofield notes view. I think I've commented on those differences before. But there are very good reasons that honest believers sincerely disagree with me on that. And I'm not going to make it a bigger deal than it is.
That being said, I'm certain the Lord's imminent return is not in the same category as the demonic locusts. The apostolic attitude toward the Lord's return was that it could happen at any moment, and they lived expecting it. Again, I'm not going to accuse people who disagree with me of heresy, but living out the faith once delivered to the saints involves living in expectation that the Lord is coming for us and could be here at any moment.
