You are incorrect. A cottage industry looking for pre-McDonald instances of pretrib preaching sprang up AFTER Dave MacPherson published his painstakingly researched book, "The Rapture Plot". It's not unlike the efforts of evolutionists scurrying about looking for evidence to substantiate that notion AFTER it was hypothesized. :nono:

Nonsense; McPherson supposed research is the research of a rank amatuer at best, an outright hack at worst.
Your blinder is that while you do strike me as an above average inteligent individual, you nevertheless, obviously allow said inteligence to be guided by a failure on your part to ask yourself "now how might I look at these things objectively - in fact, what might be objective principles for doing so?"
It's an extremely important question in helping one to arrive at an actually objective means of coming to understand what the Apostle Paul had meant by the words "prove," "all," "things," "hold fast" "that which is good" - each of which is a distinction in itself as a part of the whole.
It happens that some instinctively do that sort of thing unaware they are doing so.
The rest do not; thus the need for noting towards separating out this distinction behind actual objectivity, and in fact, the person who does separate out it consciously is bound to end up seeing even sharper distinctions than the person who just does that unaware that is what he is doing.
The rest out there, well, they forever remain in a combination of their own ideas, together with a steady overdose of an endless stream of the writings of men; most of who are merely parroting the same manner of supposed "thinking a thing through" they themselves were weaned on via their own OVERRELIANCE on the writings of men, and or words of others, all the way back to the dark ages that followed after Paul's words...
2Tim 1:15 This thou knowest, that all they which are in Asia be turned away from me; of whom are Phygellus and Hermogenes.
In EVERY single attack against Dispensationalism and its various distinctions - even at times by some Dispensationalists themselve THAT kind of an objectivity is EVER missing.
