Sort of. What I don't understand is that Jesus hasn't returned yet...
Say as who?
God/Jesus comes many times in many ways for many purposes. Jesus came with the Holy Spirit at Pentecost. Jesus came to Saul on the road to Damascus. Jesus came in judgment against Jerusalem in 70AD. The author of Hebrews stated Jesus would come a second time for a salvation apart from sin (the premillennial view of his return is decidedly about sin). In point of fact, the phase "
Second Coming" does not exist anywhere in the Bible

. That phrase is a doctrinal addition to scripture, one that is man-made, not God-uttered. Most eschatologies assume all mentions of his coming
again are the exact same coming, a
second coming, one that they hold in contradiction to the fact he came in several places in the NT (and the OT if we accept those examples as Chrstophanies).
& it's been 2,000 years since John wrote revelation,
Yes, it has. It has been 2000 years since God stated the things that would happen quickly was near. So is God mistaken or a liar? No! Definitely not. That leaves us with only one other conclusion: Jesus did come, but not as most of our end-times views say he's supposed to come. Most of these debates on eschatology are about what a particular doctrine teaches, not what scripture teaches. When the Dispensationalist, for example, argues, "
That hasn't yet happened!" what s/he more accurately means is, "
The way my end-times doctrine teaches 'X' will happen has not yet happened." That's an entirely different statement than "
What scripture teaches hasn't happened."
Fundamentally, and I mean
fundamentally, if God says, "
X will happen when Y occurs," and Y then occurs it does not matter whether or not we understand how and why X happened or what X is. This boils down to whether or not we believe God, what God explicitly stated, or do we believe what man-made doctrines say God meant. When God uses the word "near," He always means near. That is a
fact of scripture. It's a fact anyone can objectively verify if and when they open their Bible and concordance and examine every single occasion when God used the word "
near." Once the facts of scripture are gathered.... be wary of those who teach what is plainly, objectively verifiable is not what was intended. If you do that study it will be discovered that some of the uses of "
near" occur
conditionally. That is to say God says, "
When W happens then X is near." For example, "
When the Messiah comes then there will be healing," or "
When the Messiah comes people will be made seeing but not perceiving." Whether or not there was ever any report of healing or blindness does not matter because God explicitly stated those things would occur when the Messiah came. The NT gospels do confirm those two particular examples, but it did not have to do so. The moment scripture reported the Messiah had come all the events associated with his coming were going to occur. The same hold true for all those OT prophecies about the "
last days." On any occasion when the NT states the OT last days prophesy was fulfilled it immediately become incumbent upon us to believe what is written. So, when Peter speaks in Acts 2 explicitly stating Joel 2 was fulfilled at Pentecost, we don't get to deny what is plainly stated. At best we could look at the Joel 2 text and ask whether or not all of that prophecy was fulfilled in that New Testament moment but if and when we do that we had better have something in that text to support our doing so. Extra-biblical man-made doctrines in and of themselves do not justify changing what is stated. Ever.
But that happens a lot when it comes to eschatology.
I mention Acts 2 because in Acts 2 we read Peter unequivocally stating God's promise to David to seat one of David's descendants on his throne was about
the resurrection of Christ, that his body would not see decay in the grave.
This is an example of the newer revelation explaining the older revelation, the New Testament explaining an Old Testament prophecy
and declaring it fulfilled. Premillennialists (both Historicists and Dispensationalists deny Acts 2:30-31 and teach his kingdom is not complete until he establishes a physical throne with his physical presence physically here on physical earth. The essence of that view is a Judaization of Christian eschatology, the imposition of the Old Testament over the New Testament and in a way that denies what is plainly, explicitly undeniably stated in Acts 2:31. God's oath was about the resurrection, not a chair made of wood covered in gold for someone to sit on.
if God is the only one who knows when Jesus is to return
Who said God is the only one who knows?
, surely God would know in what era we would be living at upon Jesus's return.
Yep. And He stated it in His word.
For example, it is very popular for premillennialists to point to Matthew 24 where Jesus says no one will know the day or hour of his return. That is true, Jesus did explicitly state that, BUT Jesus ALSO just as plainly stated all the events he was describing
in answer to his disciples' question, would occur in "
this generation."
Matthew 24:34
Truly I say to you, this generation will not pass away until all these things take place.
And he said it
twice. He had told the Pharisees the exact same thing just a few hours earlier. No one will know the day or hour, but it will happen in
this generation. Not "
that" generation," as many say he meant. The Greek there is conjugated in the near-demonstrative. The near-demonstrative CANNOT be made to mean anything but what it plainly states. But MANY teachers, including many noted and esteemed theologians teach "this" means "that." Norm Geisler once argued "this generation" meant "that race which eventually sees those things." because the word "
genea" can be translated race, depending on the context. He later recanted. The phrase "
this generation" is used almost exclusively in Matthew and Luke. The phrase is found only one other place in the NT (Heb. 3:10), where the author is quoting from Psalm 95. All 14 of the gospel uses refer to the generation to whom Jesus is speaking at that time. Most of them are references to the OT where prophesies were tied to the Messiah's coming (incarnation) to Israel. If you check this out, make sure you start reading at Matthew 21:18 and read all the way through to Matthew 26:5. Matthew is reporting one day's events and it took him five chapters to do so. Jesus enters Jerusalem, cleans out the temple in obedience to the Levitical Law, and then leaves the city. The next day he returns and is repeated challenged by the Sadducees and Pharisees. He eventually pronounces judgment on them telling them they are graves full of dead bones and their house is desolate. He then leaves the temple where he informs the accompanying disciples the temple will be destroyed and that evening, after they've walked up to the Mount of Olives (which looks down upon the temple roof) they asked him when those things would happen. Jesus answers their question, and the passage closes with Matthew reporting the Jewish leaders had begun to plot Jesus' death. That all takes place in one day.
I'm at a understanding that Revelation was written for our generation...
Yes, that is true, but the reason it has meaning for all people of all generations (beginning with those who are Christians) is because God
was faithful and true. It is because He kept His word that we KNOW we can trust Him. The modern futurist teaches an entirely different kind of trust. They teach we're are to trust God because He
will keep His word, not because He
has kept His word.
...as we are told in Matthew 24 the things to look out for in order to be ready for his 2nd coming.
No. In Matthew 24 Jesus told
his disciples, the ones sitting there with him on the Mount of Olives to be ready. You, me, and everyone living in the 21st century are never mentioned. Go back and read that chapter and ask yourself, "
To whom does the 'you' in this verse refer?"
"
You" will see X...
"
You" will hear of Y...
"
You" will be handed over to tribulation...
Those yous are said
to the disciples, not you or me. Those yous are said
about the disciples, not you or me. Jesus did NOT say, "
They" will see and hear X and Y. He said
you will see and hear them. Exegetically speaking, these are called "
audience affiliations." We apply the text to the audience identified in the text itself. So, for example, when Paul opens his epistles with "
I Paul, a bondservant of Christ am writing to....." he is identifying his audience. It's not okay for us to apply his words to some other group of people unless the text of his epistle states otherwise.
Read the text exactly as written with the normal meaning of the words in their ordinary everyday usage unless there is reason in the text to do otherwise. Understand the words as the original speaker and his original audience would have understood them.
The only thing we should be looking for are the parts of prophecies left to be fulfilled and that's why the debate continues: premillennialists say a lot has not been fulfilled where most of the other eschatologies are more preterist (which means prophecies are already fulfilled).
So I'm still at the understanding that the mark of the beast could be a chip or a DNA change.
Okay.
I've made my case and I appreciate the time taken and the patience and kindness extended to consider an alternative point of view.
In summary, I remind you that the teachers of that model have never got even one prediction correct in the entire existence of that model. Eschatologically speaking, not a single one of them have ever been correct; they are all false teachers when it comes to these kinds of prognostications. The only way 21st century conditions like the advanced technologies suggested in this op can be made is by denying some of the most basic rules of exegesis, like the original meaning, literal reading, temporal markers, audience affiliations, and using scripture first to understand scripture. I've made some recommendations for comparative points of view and done a basic examination of a few eschatologically relevant passages in scripture. I'll leave you with three other verses to consider.
Psalm 110:1
The LORD says to my Lord: "Sit at My right hand Until I make Your enemies a footstool for Your feet."
The LORD says to His Lord to sit at the LORD's right hand until the LORD defeats the Lord's enemies. The rest of the psalm has the Lord effecting events on earth from his seat in heaven. He does not leave until his enemies are defeated. This reconciles perfectly with the fact Revelation has Jesus in heaven, seated on his Father's throne all the way through to chapter 21 and 22. Nowhere prior does the book of Revelation explicitly state Jesus is on earth.
1 Corinthians 10:11
Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come.
The
ends of the ages had come. Not their beginning, but their ends.
Matthew 24:34-41
Truly I say to you, this generation will not pass away until all these things take place. "Heaven and earth will pass away, but My words will not pass away. But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone. For the coming of the Son of Man will be just like the days of Noah. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be. Then there will be two men in the field; one will be taken and one will be left. Two women will be grinding at the mill; one will be taken and one will be left.
In the days of Noah it was the ones who were taken away by the flood that died and were destroyed. It was the ones who were left behind, eight people in all, who went on to live in a covenant relationship with their Creator. Pre-tribulational rapturists interpret this backwards. When the Son of Man comes it will be like it was in the days of Noah where many will be destroyed and those who remain will enjoy God's covenant promises.
Thanks for hanging in there with me. Let me know what you think of those other books when as you read them and I'll gladly recommend some specific sources for each eschatological pov if you like.
