There are a variety of views within Christian circles about the rapture/revelation of Christ. The most common is a pre-tribulation, pre-millennial view (my personal view 'Things to Come' by Dwight Pentecost and books by John Walvoord on Revelation or rapture are solid and academic vs 'Left Behind' Hollywood version).
The rapture is when Christ comes back FOR the Church (Jn. 14:1-2; I Thess. 4; I Cor. 15; 2 Thess. 2, etc.). The Church Age saints from the early church until now will be invisibly taken to be with Christ for 7 years (Daniel's 70th week). This is our resurrection and is NOT limited to 144,000. Rev. 6-19 describes the wrath of God, restoration of Israel, fury of Satan, etc. during this Trib. period leading up to Armageddon. The rapture is the blessed hope of the Church and we are not appointed to wrath. The trib period is not a picnic, but a time when millions will die (vs WT millions now living will never die error). The 144,000 are literal Jews who convert to Christ and are super-evangelists during this time. Many will be saved and a great crowd will be martyred and go to heaven. The Antichrist and False Prophet will be around and thrown into the lake of fire at the Second Coming of Christ after Armageddon (visible return vs 1914 invisible WT nonsense). While in heaven, believers will be judged for works/rewards at the Bema Seat judgment of Christ (2 Cor.; Rom.). Our sins were judged at the cross (not stake nonsense) and we were saved by grace through faith, not endless JW works that are useless in determining destiny. The Second Coming is preceded by signs (Mt. 24-25), but the rapture is imminent (can happen any time, perhaps today). The Second Coming is when the Church comes back WITH the church to rule/reign with Christ for 1000 years. Old Testament saints and Tribulation dead saints are raised up at the Second Coming after the Trib. Tribulation saints who survive Armageddon (hopefully many JWs, Mormons, Muslims, atheists, Buddhists, etc. will convert to the true Christ during this time...the only way a JW has any hope if not saved now) will enter the millennium in natural bodies and procreate, etc. The WT is wrong to think most will go to paradise earth with a few in heaven. Millions of believers will be in heaven. Eventually the population of earth will grow exponentially. Satan will be loosed after the millennium and some will fall away. The Great White Throne judgment after the millennium is where the unregenerate dead of all ages will be raised and judged (there is not a general resurrection, but stages). They will join beast, false prophet, Satan in the lake of fire where they will be tormented day and night forever and ever (just as God is worshipped forever and ever vs WT lie of annihilation). There will be no second chances (Heb. 9:27). JWs teach possible hope to be raised for another chance, another lie (death seals destiny). The New Jerusalem will descend above earth and there will be interaction between glorified saints and those on earth (probably beginning of mill.). After the GWT, a new heaven and new earth will be created for the eternal state. The Marriage Supper of the Lamb will be at the start of the mill. There will be judgment of nations, etc. at that time also.
Eschatology (study of end times) is based on all relevant verses, not just a proof text or two (chronology is not easy to establish, but JWs are right about a few things and wrong about many more things; see Daniel, Revelation, Matthew, Thessalonians, Zechariah, Ezekiel, etc.).
