Then if premillennialism applies John 6:54 to what they believe the second coming is in revelation chapter 19 then who do the saints reign over if every unsaved person is dead according to the verse 18 below?
Revelation 19
17 And I saw an angel standing in the sun, who cried in a loud voice to all the birds flying in midair, “Come, gather together for the great supper of God, 18 so that you may eat the flesh of kings, generals, and the mighty, of horses and their riders, and the flesh of all people, free and slave, great and small.”
Is Zechariah 14:16-19 not in your Bible? Is or is not the OT holy writ as well?
Zechariah 14:12 And this shall be the plague wherewith the LORD will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.
Verse 12 is likely meaning Revelation 19:21, for one.
Zechariah 14:16 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
17 And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
18 And if the family of Egypt go not up, and come not, that have no rain; there shall be the plague, wherewith the LORD will smite the heathen that come not up to keep the feast of tabernacles.
19 This shall be the punishment of Egypt, and the punishment of all nations that come not up to keep the feast of tabernacle
This is meaning after verse 12 has been fulfilled first. Note what the text says---that every one that is left of all the nations which came against Jerusalem.
The saved never come against Jerusalem to begin with. Therefore, we know the saved can't be meant here. Which Jerusalem is meant? IMO, the one meant in Revelation 11:1-2, for one. Except that is not meaning a literal city in the middle east.
Now note what verse 17 says---And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
We already know from Revelation 19 that the timing of verse 12 is the 2nd coming. Well maybe you don't already that, but that doesn't mean some of the rest of us don't. We need to ask our self this since verse17 is obviously meaning post the 2nd coming, the fact zero, in any sense, during the past 2000 years can possibly explain verse 12. And that verse 17 must follow verse 12. Is verse 17 meaning before or after 1 Corinthians 15:28 is fulfilled? This matters because if verse 17 means after 1 Corinthians 15:28 is fulfilled, this indicates we have to apply verse 17 to all of eternity since there would be no time period with a beginning and an end preventing it from happening.
But if verse 17 is meaning before 1 Corinthians 15:28 is fulfilled, yet post the 2nd coming, there is indeed a time period preventing it from continuing in that manner forever. And everyone here, including you, know exactly which time period I'm meaning. I'm not saying you agree, but that is beside the point.
Not to mention, it's plainly obvious to a lot of us, maybe not to any Amils as well except for maybe a few, that this in verse 5 in Zechariah 14---and the LORD my God shall come, and all the saints with thee---undeniably means Revelation 19:11, 14, for one. And that verse 12 in Zechariah 14 is because of the 2nd coming recorded in verse 5. Thus then leads to verses 16-19, which plainly, undeniably, says there are some survivors.
Of course though, except it would be absurd to do so, one can maybe argue that the one meant in Revelation 19:11 is not God, nor is anyone meant in Revelation 19:14 meaning any of His saints. Therefore, Zechariah 14:5 and this---and the LORD my God shall come, and all the saints with thee---couldn't possibly be meaning Revelation 19:11, 14, for those reasons.
