The word "rapture" is not in the Bible and the concept is not taught there either.
Some say that it is in 1 Thess 4:15-18.
It is funny that they say that the rapture is an event where people will just disappear, and those "left behind" will not know what happened. They describe this as a "secret coming of Christ", but 1 Thes:4 16, and the other verses they use, describe the Lord coming "with a shout, with the voice of an archangel, and with the trumpet of God"
This does not sound like a secret, quiet event!
This verse is speaking of the second coming of Christ at the end of the world, not a rapture! After this coming of Christ, there will be no Earth remaining for anyone to be left behind on! (2 Peter 3:10)
The “rapture” theory is partly based on a misuse of Matthew 24, especially verses 40-41, but notice closely this chapter.
In verse 3, more than one question is asked. The first question, "When will these things be?" is answered in verses 4-35.
"These things" refers to the things they had been discussing, the destruction of the temple, the destruction of Jerusalem. This was to take place before that generation passed away! (verse 34) This happened in 70 AD.
From 36 onward talks about the coming of Christ. Notice the change from "those days" in the previous verses to "that day" in verse 36 and following.
This is the answer to the last question in verse 3. "what will be the sign of Your coming, and of the end of the age?”
This passage clearly says there would be no "signs" before this event!
Notice it will be just like the coming of the flood in Noah's time. Normal life continued until the flood.
Verses 37-39 say, "But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be."
But, back to your question, notice these verses closely! The flood "took them all away" and the coming of the Lord will be like this event!
But, in the flood, who was taken away and who was left?
The evil were taken, and Noah's family were left to begin life again on Earth.
When the Lord comes, therefore, the evil will be taken away. In fact, the next chapter has the Lord telling the evil, "Depart from me!" (Matthew 25:41) They will be gathered up like weeds and thrown into the fire! (Matthew 13:40)
Those left behind will be left with the Lord (in the place where He has come)! They will be left with Jesus! This is the opposite of what the rapture teaches!
Also, they will not be left on Earth because the earth will be destroyed! 2 Peter 3:10 says, “But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.”
Read Matthew 24 slowly and carefully!
I want to be left with the Lord! I don't want to be like the evil in the days of Noah who were taken away! Those taken away when the Lord comes will be sent to eternal punishment. "So shall the coming of the son of man be!"
Jesus is king NOW! He reigns on his throne NOW!
There will be no rapture followed by a thousand year reign on Earth. When Jesus returns, the heavens and Earth will be destroyed!
