I failed to mention something in my last response, and it has some bearing on the OP's question.
The first resurrection of Revelation chapter 20, is just that:
The first resurrection of the saints of God. In other words, there was no resurrection during some "secret rapture" prior to the first resurrection.
How does this possibly pertain to the OP's question?
Well, if "someone," and a lot of these "someones" exist, believes that they are going to be "caught up" to heaven prior to the great tribulation, and then they find themselves here during it, there is a possibility that they might cave or fall away from the faith in order to preserve their own life for a season.
Anyhow, I do not know what your beliefs are in relation to "the rapture," but there is nothing in the Bible that says it is pre-tribulation. And by nothing, I mean nothing in either the Old Testament or the New Testament. Sure, I know the verses which people twist to try to support that doctrine, but none of them hold up under scrutiny. I also know the absolute futility of engaging people in that particular conversation, and that is why I initially shrank back (but for a moment) from mentioning this in my previous response.
