A Dispensational believer I will quote here and reference at the end, is arguing against Amillennialism.  He says:

“The Day of the Lord culminates with Jesus’ victorious return to the earth after His judgments have vanquished antichrist’s reign of terror. He returns as a conquering hero to inherit His kingdom.”

I want us to look at the use here of the Day of the Lord.  No I’m not arguing for the Amil view.  I too oppose it.  The millennium is one thousand years of reign commencing after the Lord returns to establish it.  It therefore cannot “culminate” with Jesus’ return.  That statement would support an Amil or a postmil view.  If the writer here means begins rather than culminates; then he still would not be correct.  Why?  Because the Lord returns to vanquish Antichrist and the remainder His enemies. It’s plainly stated.  Jesus is seen in Revelation 19:15 mounted on a white horse and returning with an army also mounted on horses.  Then in Revelation 19:19 through 20:3 we see what He does to the Beast and the armies assembled against Him during His return.  His reign has begun, as He is being viewed in the heavenlies.  These things happen as a result of His return and they establish His reign.  He is not culminating but beginning the millennium (the day of the Lord). 

Revelation 19:19  And I saw the beast and the kings of the earth and their armies assembled to make war against Him who sat on the horse and against His army. (NASB1995)

An opposing army is also present on earth at His coming.  Armageddon brings Him back.  Revelation’s bowls confirm this:

Revelation 16:15  (“Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his clothes, so that he will not walk about naked and men will not see his shame.”). 16  And they gathered them together to the place which in Hebrew is called Har-Magedon. (NASB1995)

Scripture compliments itself if we let it.  The Dispensational attempt to make the Tribulation be equal even in small part to the millennium is refuted once again by the Scriptures.  Christ’s 1000 year reign begins with His coming to earth.  He does not destroy all evil during the Tribulation, but He does begin when He returns.  The return begins as recorded in Isa. 63 vs 1.   Where He is seen protecting Israel from annihilation. In Isa. 62:11, God announces to Israel, “Lo your salvation comes”  then He comes and begins His fight alone as Israel’s King in Royal robes, but when they see Him His Royal robes are already blood stained due to His beginning this confrontation with these Enemies wherein we see the first outpouring of Orge wrath carried out to set the stage for His coming in Rev. 19:15 where He is wearing these same blood stained royal robes. 

Jesus will see us through this great Tribulation. 

Revelation 7:9  After these things I looked, and behold, a great multitude which no one could count, from every nation and [all] tribes and peoples and tongues, standing before the throne and before the Lamb, clothed in white robes, and palm branches [were] in their hands; (NASB1995)

And we hear as we read on that these are those who have come out of the Great Tribulation.  We who love Him will stand with Him in that day and our numbers will be great. And we will witness the reaping of the harvest.
