I don't understand your explanation, nor does it align with Matthew 25.
Matthew 25 states that all nations will be assembled at the return of Christ and will be judged. Eternal life or eternal punishment are the two options..no other.
Matthew 25 is speaking of a judgment [/separation] of "still-living" persons [of the nations (plural)] at the time of His "RETURN" to the earth; the judgment/separation has to do with who will ENTER the MK age (NO "RESURRECTION" is taking place in this chpt (nor in Matt13 upon which His disciples' Q of Him in Matt24:3 was BASED, and which kicks off this whole two-chpt answer/response by Him [note: v.25:40,45 "the least of these My brethren" is not speaking of those BEING judged/separated here (the Sheep/goats, by contrast, are "of the nations [PLURAL]" who are the ones being judged/separated in view of how they themselves either AIDED [/blessed] "the least of these My brethren, or did NOT do so)]
And, there is no intervening period.
The "intervening" time-period is NOT "between His 2nd Coming/Return to the earth" [here] and the START of the MK age; but [instead]
…[but] IS the MK age [the time-period between His "2nd Coming/Return to the earth [Rev19:19,21/16:14-16,20:5, i.e. the FIRST of the TWO "PUNISH" words in Isa24:21-22]" and the later "GWTj [Rev20:11-15, i.e. the SECOND of the TWO "PUNISH" words in Isa24:21-22!]
I encourage folks to read the Gospels and Epistles without dispensationalist blinders that insert gaps where they don't exist.
And I encourage the readers to not disregard all of the timing- and chronology- and sequence-clues and wordings which are abundant, but which the "amill-teachings" [and others] thoroughly disregard, as though insignificant and of no matter/consequence
So, when Christ returns, this happens:
Matthew 25:46 46 And these will go away into eternal punishment, but the righteous into eternal life.” (ESV)
There is no room for an intervening period.
Both the Isa passage I supplied and the Rev passages I supplied (which are parallel) tell of a time period which FOLLOWS the FIRST of the TWO "PUNISH" events.
By the way, if someone else wants to try to explain your exegesis of 1 Corinthians 15, I'm open to it. I cannot understand the way that you phrase things. Your writing style simply doesn't work for me.
K, I'm just saying that 1Cor15:24's " *THEN the end" does not mean what the "amill-teachings" insist that it does, when THEY read it to be saying "then immediately [/right then] the end" [as tho nothing further is left to happen, His reign has already (at this point) accomplished "the last enemy that shall be destroyed is death," according to their "chronology" which misses the chronology and timing issues (in abundance) provided in Scripture]; and
...rather than what Revelation 19:15b's wording says in its "FUTURE tense" [at that point] "And He SHALL shepherd them [/the nations] with a rod [/sceptre] of iron [righteousness and strength]" where the wording of 1Tim6:15 parallels also Rev19:16, and 1Tim6:15 [one of only 2x "KING" is used in all of the epistles] is also "FUTURE"... "SHALL SHEW [/openly manifest]" (and which SEQUENCE "agrees" with other passages such as Dan7:27 [following the specific time-slot in v.25] and where that says, "the greatness of the kingdom UNDER the whole heaven"... [too many more...]
* THIS "THEN" is a SEQUENCE WORD ONLY with NO "TIME-ELEMENT" attached, and the LIST is telling the SEQUENCE;
