Anyone who goes to lengths to deny that there will be a rapture/resurrection event to heaven, should it take place, will not be included.Denying a rapture to heaven does not disqualify one from being raptured. The only requirement is to be a saved Christ who is alive on Earth when it is time for the rapture. This is why it isn't possible to somehow miss the rapture if you are saved and alive at that time.
It is similar to anyone who goes to lengths to deny Jesus's death on the cross provides for atonement of one's sins - will that person be saved if they die in that state of denial ? No.
