Your statement was "Oh, yeah, dispensationalism teaches it could be any second." with "it" being "Second Coming of Jesus, in Final Judgment" from the quote of the post by Alan Gross.
My understanding of the defining characteristics of "Dispensationalism" are seven dispensations (eras) of God's interaction with man:
- Innocence (pre-Fall)
- Conscience (Fall–Noah)
- Government (Noah–Abraham)
- Promise (Abraham–Moses)
- Mosaic Law (Moses–Christ)
- Grace (current age)
- Millennial Kingdom (1,000 year earthly reign of Christ, yet to come)
For a "pre-tribulation rapture" dispensationalist (the sort most popular in the USA at the moment) the return of Jesus for his saints/Church/bride is imminent, but his judgement must wait until after the great tribulation.
For a "mid-tribulation rapture" dispensationalist the church/saints/bride must endure the first 3.5 years under the "antichrist" before Jesus returns for His people, and Judgement still waits until his second coming, so His return is less "imminent".
For a "post-tribulation rapture" dispensationalist (the most common pre-19th Century) the church/saints/bride must endure the Great Tribulation before Jesus returns for His people and Judgement, so His return is less "imminent".
For dispensationalists that see the "Millennial Kingdom" as fulfillment of the OT promises to Israel, there is a SECOND return Resurrection of the new saints at the end of the 1000 years and THEN comes the final judgement.
So "Dispensationalism" is a BIG TENT with a lot of views that do not easily suffer generalizations.
