I like Mark Becker. He makes some good points but lands a little further in the other direction therefore perhaps a little bit of over correction on the other end of date setting.
Starting with the not knowing the day or hour - if we are to take that scripture in context with the rest of Scripture, what do we do with Paul's sentence "as we see the day approaching" in Hebrews 10:25? Obviously they were expecting the Lord back then too so expectancy is built into the Rapture.
Paul says "but you brethren are not in darkness" in 1 Thess 5:4 obviously expecting that the church WOULD know when the time was coming.
2 Thess 2 Paul gives a correction to those who thought they were in the Tribulation, reminded them of previous teaching and explained that the AC - the man of sin hasn't shown up. He was speaking to people in the early days of Nero's reign. They were sure Nero was the AC and they were in the Trib. For the "scholars" who say it's later, they forget that Paul was beheaded by Nero. He wrote 1 & 2 Thess, and he couldn't have written something after being beheaded, therefore it's in the early part of Nero's rule.
Paul was giving a correction that it wasn't then. The apostasy comes first - whether that is the apostasy of the church falling away from good teaching or the Rapture, it doesn't matter- because Paul makes it clear that the apostasy (whatever way we take it) comes first.
So those 3 passages all give the impression that Christians would, even should know the general time frame.
So yes we don't know the day or hour, but I think we can know the season, or "see the day approaching". That comes as we see things that can only be inside the Tribulation start to shape up around us. Things like satellite systems and cellphones so the whole world can see the 2 Witnesses in Jerusalem come back to life. In previous decades it would have been impossible to have the entire planet under a single monetary system or world govt. With computers, and now AI what was once a puzzle has become realistic.
Knowing the season, seeing the day approaching doesn't give us licence to set dates- because that does get into the day or hour.
I loved him including the genetic research angle because that
Genetics Research Confirms Biblical Timeline does confirm the 6000 year theory of the age of mankind.
As for the timelines coming out with a 168 year variance, that simply says how close this all is. 168 years is still close when looking at a 6K timeline. So people differ on the date of creation, or Egypt, or even the Cross (although that is about a 4 year variance). Bottom line it's less than 200 years out any way you look at the timeline, and the date of the Cross may well be something that all of time revolves around.
Bottom line it's all pretty close. So that doesn't wash out the millennial day theory, only the people who use it to set exact dates or suggest that it absolutely HAS to all be fulfilled by the 2K anniversary of the Cross. What if it turns out to be the 2K anniversary of the destruction of the Temple and the absolute end of the sacrificial system? (I don't think so but what if) God is in charge of history and whenever the time is right, He will send the Lord to get us and whenever the time is right He will allow the signing of the infernal covenant between death and Hades that Isaiah references, as well as Daniel.
I like how he puts this:
"
No one should ever be able to say in heaven, “I am the only one who accurately calculated God’s chronological timeline,” to the exclusion of everyone else. This is Creator God’s divine chronological timeline and not ours; though, as His creations made in His image, God certainly desires us to know approximately where we are, hence all the internal historical Biblical data He provided to us."
As he gets into the measurements of time, the different calendar systems, I agree with him, there is a lot of variation and the Bible doesn't clear it all up.
There are hints though. The date of Jesus arriving in Jerusalem- the date in 1948 of them becoming a nation, 1967 when they got the Temple mount back and then inexplicably refused to keep it. Those are embedded within certain time prophecies- 1948 and 1967 only becoming obvious after they happened. Jesus scolds the Pharisees for not knowing the day and hour when He presented Himself on Palm Sunday. It was clearly predicted by Daniel, as Sir Robert Anderson laid out for us to plainly see.
The recent discovery of the Essene calendar system which is ongoing, (see Dr Ken Johnson's work) sheds further light on how the Essenes saw time, and how they calculated Passover- differently to the Pharisees and Sadducees. Oddly enough the Essenes had predicted that what we know of as 32AD would be the year.
When he gets annoyed with the people who insist on exact 4K year dates here I agree with him. It's approximate. The ancient understanding of Elijah's ages was always approximate. It wasn't precise. (Although the time God gives a precise date thru Daniel, for Jesus to ride in on the donkey presenting Himself as the Messiah, Son of David, they SHOULD have known)
Although we'd all like to know precisely when the world began, Abraham was called (that is supposed to be approx 2K) and from Abraham to Christ is approx 2K. The age of grace is approx 2K followed by the millennial reign.
Date setters need precision, so they read that into things. It doesn't change the approximate time frame.
I also agree with him here:
"
To our readers who get excited when they hear someone project a day, or a date, or a timeframe for the rapture of the church: Are you tired of having your heart broken? It does not have to be this way. If we just watch and wait as our Lord commanded us, we will never be disappointed."
I don't see a problem with a general time frame as speculation- a theory as long as people aren't dogmatic about it because time frames come and go. I saw a lot of hype around the 40 years of Israel back in the 80's. Harold Camping and others -88 reasons why Christ will return in 88.
I think he's right about too much of this speculation raising people's hopes and then they become the scoffers that Peter warned of "where is the promise of His coming?"
But that passage points to an even deeper problem with how people would view the Word of God in the end times. How the flood of Noah and Creation itself would be under attack. And it's all related according to Peter. They don't just scoff at the Rapture or the Second Coming. They don't seem to care about the Flood or Creation. It's like they deny the bookends of the Bible. Which is exactly what we see today in the church.
I've always thought this passage isn't just speaking about unbelievers. It's about people who have heard of Creation, and Noah's Flood and deny it happened because everything just rolls along like it always does. Uniform processes of change over billions of years.
If we believe in a real Creation (and fall of Adam), and a real Flood, then we need to pay attention to the prophecies in the Bible and that would include the coming of Jesus.
But somewhere along the line, a lot of people would start to scoff. And today the scoffing isn't coming from the world so much, it's within the Church. The world doesn't care if we think God created everything in a set of 7 literal days or the billions of years that the Old Earth Creationists theorize. They look at us like they look at people who believe the earth is flat, or a giant turtle etc. We are a joke, nothing more.
The people who get angry and scoff are the ones within the church who've maybe had one too many encounters with a date setter and decided that is never going to happen. They seek out alternative theological positions that exclude the Rapture at least in the near term.
But to turn that back around, Peter notes that is one of the signs of the very last days. The scoffers weren't a feature of the early church. The church of the dark to middle ages had already forgotten that teaching.
The time of the scoffers is within the last 200 years or around the time dispensationalism rediscovered the Rapture which had been a feature of the early church.
So here we all are. Scoffers are scoffing, date setters are setting dates, people are getting disappointed and losing hope and it looks awfully like the season to me.
