Dispensational eschatology is one of the few things that they do not prooftext. it is unclear what you mean by this. Do you mean eschatology which recognises that the current age is the Church Age etc?
They have to take large chunks of Daniel and Revelations, then sprinkle in Thessalonians 2 and mix it all together. It is interesting to note that in order to get everything to fit, they take parts of each book and stitch it together into one grand timeline.
it is a matter of observation that not all prophecy occurs in one place! So the nature of your objection is unclear. EG When Gabriel addresses Daniel regarding 'the end times', it clearly relates to the end times!
I am merely expressing the difficulty of putting all the pieces together results in some interesting interpretations such as 2 and 3 second comings of Christ.
It is far more productive to take a more socratic approach and just keep asking questions.
it would only be "more productive" if you ended up with a coherent narrative, which you don't.
I don't have a coherent narrative? I guess your right. I don't need to know exactly what occurs in the end times. It isn't an important part of my life. I know that God wins, do I need to know what all the details are?
e.g. why is there no comprehensive timeline in the Bible, why is it split up amongst several books,
because that is the nature of revelation.
The nature of revelation is to be super confusing and disjointed to everyone except the the evangelical Christians who proclaim it to be really easy to figure out if only we listen to them? Ok...
how do you know what is overlap and what is part of the timeline, how do you know you are interpreting it correctly,
by placing yourself under the lordship of the Holy Spirit and assuming that God intended to communicate.
As this is why there are only 40,000 denominations around, because they all agree to the interpretation.
I don't know about your Holy Spirit, but the Holy Spirit I have faith in does not lead to near as much confusion.
why has this doctrine been around for only 150 years and really only in the US, etc. it hasn't and isn't but keep perpetuating the myth.
I'm sorry, I'll rephrase. It is a doctrine that Daniel and St John taught but was mysteriously lost for 1850 yrs of Church history only to be heroically restored by St John Nelson Darby and the "true church" of Plymouth Brethren although I suspect that many of their other teachings you would find objectionable so the real true church didn't actually show up until St. Hal Lindsey wrote the new appendix to Scripture: "The Late Great Planet Earth".
No, that doesn't sound like "Restorationist" Christianity a la Mormon/Jehovah Witness at all...
