Jeremiah 4 & 6 = 1 Thess 4 & 5 and 2 Thess 2

Looks like a very interesting study, uscgvet   ;-)   

I totally with you and Ireneus and Jaco  ;-) that Jeremiah 6 and 2 Thessalonians are the same event.     I also totally agree that we have to look at the Old Testament to fully understand the New Testament.  
In the 6 verses listed, there are some similar words, and 5 of the 6 are describing one thing and 1 is totally different.   

I think everyone would agree that the two most universally used and well-known passages to explain and support the rapture are both by Paul and are

1 Thessalonians 4:15-17 and I Corinthians 15:51-52.   Paul explicitly connects the rapture - [Harpazo - to be caught up, snatched up quickly by force] with the resurrection of the dead in Christ in a nano-second- the blink of an eye- instantly.   The Greek word is "Atomo" where we get our word atom, the smallest particle. 

So we can agree that the passage in 1 Thessalonians 4:15-17 is the rapture.   

The other 5 verses are the 2nd coming.  Totally separate time, place, purpose, and group, and length of time.   The thing that confuses people are the trumpets.  

The "Day of the Lord" is a set phrase from the Old Testament, understood and used by 10 writers, over a span of 600 years, from  the 10th century BC to the 4th Century BC.  
To put this in perspective, - this phrase already had a well-established meaning more than 500 years before Christ was born.   

The phrase appears in 19 passages in the Old Testament and there are 45 different terms and words used - not counting the phrases which appear multiple times like dread and terror.   
The words are always negative -- Fear, vengeance, destruction, fury, calamity, terrible, dreadful, anguish, war, bloodshed, punishment, and it is described as being chased by a lion, confronted by a bear and when you get home, you get bitten by a snake, and the day women are ravished.    

Amos says "Woe to you" - A cry of despair, and a term used to announce judgment from God- "who desire the Day of the Lord."  

To help make the point, i going to highlight the words from the passages that the writers use to describe them in your quote box above in purple.    See the pattern over and over - Fear, anguish, pain, destruction, Woe, spoiler, not able to escape.    
It's not just that the words to describe the rapture and the Day of the Lord are starkly different.  The words are literally mutually exclusive.   

Let's look at an example.  Tim says I'm going to describe something to Bob and Rob.  It's Gray.  

Bob - "It's smoke"  everyone knows it's gray.  
Rob -"uh, no,  it's a tree trunk."  Just because something is gray doesn't make it smoke.      We need more words. 
It's gray, it's tiny, very timid, runs away at every chance, furry, often described as friendly in books.   
It's gray - it's massive, terrifying, aggressive, attacks unprovoked, razor sharp teeth, vicious predator.      
Anyone would not logically say that these words are describing the same thing.    The words are mutually exclusive.  Something cannot be tiny, and at the same time massive. 
Something cannot be timid, and at the same time aggressive, vicious predator.   The terms are mutually exclusive.  

**The confusion is also made worse because many translations of 2 Thessalonians 2:2-4 incorrectly say "Day of Christ", but the passage in the Original says "Day of the Lord"- this passage is not talking about the rapture.   
It is this passage - taken out of context, that is often used to show that these the Abomination of Desolation and the Great Apostasy happens before the rapture - because the KJV and others say Day of Christ.   

When we understand that the original says Day of the Lord - it makes a huge difference. !!    These things happen before the Day of the Lord- which is fulfilled in the Day of Atonement - understood as the day the door is closed, and the day the sentence is pronounced.  

In the same way that the words to describe a mouse and a Great White shark are mutually exclusive, the words used to describe the rapture and the Day of the Lord are mutually exclusive. 
    - We are told to long for, - look forward to the rapture - Titus 2:13 New Living Translation "while we look forward with hope to that wonderful day when the glory of our great God and Savior, Jesus Christ, will be revealed."   The rapture is the wedding of the Messiah.    The parable of the 10 bridesmaids is a rapture picture, and it's also compared to a feast.  

    - We are told NOT to desire the Day of the Lord - It's wrath and destruction from the Almighty - and is described as being bitten by a serpent.   That's not a wedding, guys. 

What's interesting is that over and over throughout scripture we see a clear pattern of the door being shut, and judgment, or punishment follows.  The Ark is a symbol of the rapture.  The people went in the open door.  Noah and his family knew in advance - no random surprise event.  They were lifted up above the flood, and delivered on a Feast Day.  Unleavened bread/ Passover.   The door was shut and judgment came.  
Lot - the door was shut - and judment came.  
The same wedding parable in Matthew 25 that is a picture the rapture.  The open door, the wise knew the time. The foolish did not.  The door was shut and Judgment came.  

Lastly - it's important to note the phrase "The Day of the Lord" is like a Thief in the night.  It's not the LORD - it's the Day of the Lord.  The Thief in the night is a well-documented idiom, that goes back before Christ - and it's an ancient Hebrew idiom for the Captain of the temple guard.   

He would go through at night - looking for any temple guards asleep on their watch.  If he found one sleeping, he would light his clothes on fire.  The guard would wake up - maybe even feel the heat and run out into the temple court and throw off his robe and be in his boxer briefs.   

This is why Jesus says to the dead and sleeping church in Revelation - IF you don't repent, - then i will come on you like a Thief in the Night.
