So while one understands their views another can understand at what point in history did people introduce or reintroduce (this speaks to your post above) that view.
See, not all Christians believed this view of futurism in the past and not all believe it today.
Ah, but the point you were making and which Wikipedia also erroneously makes in that it was a concept invented in the 18th century... it was not.
As I said, along with a multitude of other biblical precepts, one is free to believe them or not. Take Trinitarianism, the resurrection and Jesus Deity among many others... there are religious movements to fit all desires and shades of belief. What is important for me though is that the bible actually shows us what is biblical and to believed and what is not... without a shadow of doubt.
I would not be dispensationalist if the bible did not clearly show Dispensationalism, I would not believe in a rapture if the bible did not show this to be a biblical expectation. I define Christianity by what the bible says, not the other way around.
