That interpretation of Luke 21 is very complicated and confusing. Unfortunately it neglects the basic structural outline of the Olivet Discourse and basic principles of hermeneutics; namely that the simplest explanation is likely the right one and should be favored over a more complex alternative.
In the Olivet Discourse Jesus provides an outline of the end times (Luke 21:8-19; Matthew 24:4-14).
Then He discusses the time of Jacob's trouble, or the great tribulation, in greater detail (Luke 21:20-24; Matthew 24:15-28).
Thanks for the nice breakdown. However, it does not appear that you understand that Luke and Matthew are talking about different events in these verses.
Next He answers His disciples question about the sign of His coming. Here He also provides that the resurrection takes place. (Luke 21:25-28; Matthew 24:29-31)
Agreed.
At this point Jesus pauses the chronological progression to provide warnings to His followers, the first being the parable of the fig tree. (Luke 21:29-33; Matthew 24:32-35) These parables are all concerning the event He just described.
After these warnings Jesus explains what happens next concerning those who claim to be His servant. (Matthew 25:31-46)
Of course being a dispensationalist you would believe it speaks only of Israel, dispensationalism is a system of theology that is dependent on the pre-tribulation rapture and overly ridged distinction between the Church and Israel. This system also attributes that some of the NT is not for the Church at all either.
There is absolutely a distinction between the Church and Israel. Part of Israel cannot see until the fullness of the Gentiles comes in.
Romans 11
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
The fullness of the Gentiles will come in at the pretribulation rapture which is the barley and wheat harvest.
I can not agree with those three tenants of Dispensationalism. Luke 21 only mentions the "harvest," as you called it, as being near the Cosmic signs immediately preceding the Day of the Lord. The same point that Matthew 24 attributes the gathering of His Elect. Everything else after is reflecting on the signs He just described.
The harvest in Luke 21 and Matthew 24 can be found in Revelation 14.
4 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
17 And another angel came out of the temple which is in heaven, he also having a sharp sickle.
18 And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
19 And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God.
If you really want thought provoking ideas, Revelation 16:15 paraphrase of several of the warnings immediately proceeding the 7th plague (Bowl).
Sorry. I am not following you brother.
Furthermore, the key signs (lightning, sounds, Thunder, Earthquake, etc.) are present in the 7th and 7th seal, the 7th trumpet, and the 7th Bowl.
The difference is that the voices, lightning, thunder and earthquakes of the 7th seal occur at the beginning of wrath. The same events of the trumpets and Vials occur at the end of wrath after Armageddon.
Revelation 20:6 states the First resurrection is after the tribulation... but I suppose either First doesn't really mean First or that doesn't apply to the Church?
The first resurrection is the resurrection of the righteous, The dead in Christ are righteous and they will be raised before the seals are opened.
In Daniel 12 we see another resurrection of the righteous just after the great tribulation
Daniel 12
And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
Here is the great tribulation in Revelation 14
Revelation 14
13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
And here is that harvest which is BEFORE WRATH.
Revelation 14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
17 And another angel came out of the temple which is in heaven, he also having a sharp sickle.
18 And another angel came out from the altar, which had power over fire; and cried with a loud cry to him that had the sharp sickle, saying, Thrust in thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.
19 And the angel thrust in his sickle into the earth, and gathered the vine of the earth,
and cast it into the great winepress of the wrath of God.
Here is the dead being judged after wrath which is what you are seeing in Revelation 20
Revelation 11
18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
By the way, the time of the Gentiles ends with the tribulation... that's why the Gentiles are trampling the temple underfoot. Rev 11:2
Israel is not delivered from their chastisement until after the tribulation and fullness of the Gentiles.
You are making a error here brother. FYI, The times of the Gentiles and fullness of the Gentiles are different events. You can probably search on the internet and get a good description the difference.
