Jesus, in Matthew teaches a time of great trivulation followed by the second coming and the gathering of the elect. If you think some or all of this time is 'the day of the Lord' I do not see why you bring this up in a discussion where you support pretrib or midtrib. The gathering happens after the tribulation.
I've said that
"the Day of the Lord" is an
earthly-located time-period of much duration:
"a-period-of-time-[not-lasting-merely-24-hrs]-of-JUDGMENTs-followed-by-a-period-of-time-[also-not-lasting-merely-24-hrs]-of-BLESSINGs" [<--ALL THAT]... so I've pointed out that it consists of
ALL THREE of the following:
1) the 7-yr tribulation period
upon the earth (the
"DARK/DARKNESS" /
"IN THE NIGHT" [/NIGHT WATCHES] portion); and
2) His Second Coming
to the earth (the "
SUN of righteousness
ARISE" portion); and
3) the 1000-yr reign
on/over the earth (the "reign...
GLORIOUSLY" portion)
^ ALL THREE (
= "the Day of the Lord"... it is
not merely "a singular 24-hr day").
In view of
that (which I've stated repeatedly ^ ),
the
Matthew 24:29-31 passage (your passage) is referring to the time-slot of His Second Coming
to the earth (recall what I've said about the Olivet Discourse). So I've said that
Matthew 24:29-31 is what takes place AFTER the trib yrs, at the time-slot of His Second Coming
to the earth, FOR
the earthly MK age to commence [and is
NOT covering the Subject of "our Rapture"
at all, per context]).
Compare the following two passages (I've pointed out in several posts):
Matthew 24:29-31 [ylt] -
29 ‘And immediately after the tribulation of those days, the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from the heaven, and the powers of the heavens shall be shaken; 30 and then shall appear the sign of the Son of Man in the heaven; and then shall
all the tribes of the earth smite the breast, and
they shall see the Son of Man coming upon the clouds of the heaven, with power and much glory; 31 and he shall send his messengers [/angels] with
a great sound of a trumpet, and
they [the angels/messengers] shall gather together his chosen
from the four winds, from the ends of the heavens unto the ends thereof [i.e. from the extremities (note: this is not saying the destination is "TO Heaven")].
Isaiah 27:12-13 [and 9a for good measure, this time] [bsb] -
9 Therefore Jacob’s guilt will be atoned for,
and the full fruit of the removal of his sin will be this:c [<--note:
see Rom11:27 in its context]
[...]
12
In that day the LORD will thresh from the flowing Euphratesd to the Wadi of Egypt,
and you, O Israelites, will be gathered one by one. 13 And
in that day a great ram’s horn [/trumpet] will sound, and those who were perishing in Assyria will come forth with those who were exiles in Egypt.
And they will worship the LORD on the holy mountain in Jerusalem.
[
compare also Isaiah 24:[21-22]23, which passage I've shown in past posts to be parallel time-wise
with Rev19:19,21/16:14-16/20:5 at the time of His Second Coming
to the earth; see also
Isa11:11-12]
[these passages ^ are
NOT about "our Rapture"... but they do take place WITHIN the overall time period known as "the Day of the Lord" which has three parts total (see part
"2)" from the list above, for the portion regarding
"His Second Coming to the earth" which is where
Matt24:29-31 "fits" in--
AFTER the trib yrs, and at the "
GREAT trumpet")]
