Hi the Bible is a history of what happened and contained in that history are revelations. Some of these revelations are prophetic. The prophecies coincide with moral laws as well as judgement is based on behaviors. The history of the Bible contains an expanding list of promises of God and explicit prophecy about future outcomes. The end times and the rapture are not isolated as events unto themselves. To really understand it you need to integrate the total sum of all the themes and promises made in the Bible. Rev 10 says when the 7th angel had sounded its thunder the mystery of God as revealed through his servants the prophets would be finished.
The basic outline of what will happen is understanding that there is a specific 7 year period known in the new testament as the tribulation but in the old it is called by Jeremiah as the time of Jacobs trouble and in Daniel the 70th week and in Joel and elsewhere the great day of the LORD. The history of Israel is one that had a conditional covenant, that is one based on blessings for obedience and judgment for evil practices. The law predicted Israel would be destroyed and kicked out of the land for breaking the covenant and this has happened now twice. Once they were kicked out 70 years in Babylon and then from 70 AD to 1948 a long expulsion. God promised unconditionally to Abraham that that land of Canaan would be given to his heirs forever. God reaffirms this in 2n Sam 7 and in Luke that there is time that Israel will dwell safely and in peace having been delivered from their enemies and this peace was to last forever. Now this has never happened so it is either failed or still future.
The 7 year tribulation has a specific mid point where the antichrist commits what is termed the abomination of desolation. Jesus said to watch for this and to flea when you see it. It is when the antichrist puts an end to the daily sacrifices. Now Israel has not had the sacrifice since 70AD. Yet they are back and a group called the temple institute has replicated everything necessary to resume these sacrifice not performed since the destruction of the temple in 70 AD. In Hosea 3 God said this 4 For the children of Israel shall abide many days without king or prince, without sacrifice or sacred pillar, without ephod or teraphim. 5 Afterward the children of Israel shall return and seek the LORD their God and David their king. They shall fear the LORD and His goodness in the latter days
You see Israel has gone many days without the sacrifice and now they have prepared its return. The tribulation requires the sacrifices to be up and running for the antichrist to put and end to them. Anyways i went through all of this to demonstrate that the specific themes mentioned in scripture are lining up as history is arcing through the unlikely odds of these things ever coming to pass.
The rapture has to do with a promise that we will not all die and those at the last trump will be raised and meet the Lord in the air with the dead in Christ rising 1st. The debate as to if this is pre mid or post tribulation is a long one. If you read zech 14

you see Jesus coming with his saints destroying enemies and establishing a throne. Even the geography is redefined.
In REv 20 4 And I saw thrones, and they sat on them, and judgment was committed to them. Then I saw the souls of those who had been beheaded for their witness to Jesus and for the word of God, who had not worshiped the beast or his image, and had not received his mark on their foreheads or on their hands. And they lived and reigned with Christ for afn thousand years.
You want to be sure you are in Christ and weather you have died or are one of those who are translated and meet him in the air that you are on this side of it. This is really a huge subject but the tribulation is the wrath of God and Jesus promised not to appoint us to wrath and that this day was one no one would know about so if it is at the end of the tribulation we are given the exact amount of days from the end of the sacrifices till the 2nd coming so that idea is cancelled.
