Paul is telling the Thessalonians/believers that they are not in the Day of the Lord because the APOSTASIA comes first AND you haven't experienced THIS APOSTASIA as of now. But, have you experienced THE apostasy in your life? Whatever the APOSTASIA is, it must be something observable, otherwise how would you know it if THE APOSTASIA happens. It must be something that all believers can observe so they know it is THE apostasy that Paul is referring to. Paul tells Timothy that in the later times there will be an apostasy, he even gives examples of what this apostasy will be like. THE apostasy is not a local event, but a slow progression of events that ultimately will result in THE apostasy.
Jude records an apostasy, but it was not THE apostasy obviously. The pre-tribbers position has an identifiable event that is THE APOSTASIA. Something that can't be ignored, not even by the world. So, is THE apostasy an observable event such that we can say, "Yes!! We are in THE apostasy that Paul told us precedes the Day of the Lord."
Just thinking out loud
