Good post.
The word "parousia" is only mentioned in Matthew 24 of the Gospels, and that 4 times...[the rest are in the Epistles]
Here are the 3 different forms of that greek word:
parousiaV <3952> Mentioned 6 times. Matt 24:3; Philippians 1:26; 2 Thessalonians 2:1, 8; James 5:7; 2 Peter 3:4
Parousia <3952> Mentioned 15 times. Matt 24:27, 37, 39; 1 Corinthians 15:23, 16:17; 2 Corinthians 7:6,7, 10:10; Philippians 2:12; 1 Thessalonians 2:19, 3:13, 5:23; 2 Thessalonians 2:9; James 5:8, 1 John 2:28
parousian <3952> Mentioned 3 Times: 1 thessalonians 4:15; 2 Peter 1:16; 2 Peter 3:12
Peter and James shows the full end of all things happens at that "parousia" of Matthew 24.
and this was spoken well before the decimation of Jerusalem and the OC Levitical Temple and Sanctuary:
1448. eggizo eng-id'-zo from 1451; to make near, i.e. (reflexively) approach:--approach, be at hand, come (draw) near, be (come, draw) nigh.
1 Peter 4:7
Of all-things/pantwn <3956> yet the End has drawn nigh/hggiken <1448>;
be sane then! and be sober! into the prayers,
James 5:8
be patient! and stand-fast! the hearts of ye,
that the Parousia <3952> of the Lord has drawn nigh/hggiken <1448>;
Maybe a good post to you, but I myself like to think things through a little more before coming to any final conclusions about something.
Matthew 24:27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming(parousia) of the Son of man be.
Notice something here though.
2 Thessalonians 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming(parousia):
9 Even him, whose coming(parousia) is after the working of Satan with all power and signs and lying wonders,
These 2 verses in 2 Thessalonians 2:8-9 aid us in determining the coming in Matthew 24:27 and the timing of that coming. 2 Thessalonians 2:9 indicates it is after the working of Satan with all power and signs and lying wonders.
What working of of Satan with all power and signs and lying wonders?
How about this one for one?
Matthew 24:23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
25 Behold, I have told you before.
So wherever one places the coming meant in 2 Thessalonians 2:8-9, that is where they should place the coming in Matthew 24:27.
And since not even Preterists likely deny the coming meant in 2 Thessalonians 2:8-9 is meaning the 2nd coming, Preterists then must conclude Matthew 24:27 is referring to the 2nd coming based on 2 Thessalonians 2:8-9, and that it is after the working of satan with all power and signs and lying wonders.
Matthew 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Obviously the trib of those days in verse 29 are referring to Matthew 24:21. That makes the coming in verse 30 meaning after the great trib, and also after the working of satan with all power and signs and lying wonders, since that working of satan occurs during the time of the great trib, and not after the time of the GT instead.
