The 2 passages in the video (1 thess 4 and 2 thess 2) both speak directly of the ‘day of the Lord’ as the topic paul is speaking on.
The interpretation of the rapture/harpazo is correct. It is a catching away. Everyone argues so much about this word though that they fail to address the meaning of the word ‘meet’ that follows (meet the Lord in the air).
In the Greek, the word used for meet is apantēsis. There are at least two other words for meet used in the New Testament and they have slightly different meanings. In this instance, it means to come out of a place to welcome an approaching dignitary and accompany them on the last part of their journey to you. It is used of Paul on his journey to Rome, where the people came out to meet him.
In 2 thess 2, where the bloke in the video claims apostasia is the rapture, there isn’t a Bible scholar in the last 2000 years that has associated the word with a rapture. It’s not what the word means and you can’t use the literal translation of harpazo one minute and then use a really tenuous link to another word in the next instance to support your case. It is linguistic gymnastics of the worst kind. Where apostasy means ‘departure’ or ‘falling away’ or ‘rebellion’ in the passage, it clearly indicates something that happens before the day of the Lord. As Paul describes the harpazo in 1 thess 4 as something that happens on the day of the Lord, the ‘departure’ cannot possibly be the rapture.
Here is what Jesus says about the timing in John 5 -
28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,
29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
‘The hour’. The dead in Christ rise first. The those who are alive in Christ. Then judgment is brought on all those who are not His.
Peter describes what happens on the day of the Lord - the heavens will disappear with a roar, the elements will be destroyed by fire, and the earth and everything in it will be laid bare/burned up.
The rapture and second coming are the same event. The day of the Lord. And there are no second chances for those who haven’t accepted Jesus as their saviour by then.
