The English word 'rapture' derives from the Latin verb 'Rapere,' meaning 'to carry off,' or 'to catch up.' Although the term 'rapture' is not found in the Bible, the theory is based on Scripture. Those who accept the Rapture theory believe that all non-believers on earth at the time will be left behind for the tribulation period.
There are many Christians who believe that the second coming of Jesus Christ will be in two phases. First, He will come for believers, both living and dead, in the “rapture” (read 1 Thessalonians 4:13-17). In this view, the rapture—which is the transformation and catching up of all Christians, dead or alive, to meet Christ in the air—will be secret, for it will be unknown to the world of unbelievers at the time of its happening.
The effect of this removal, in the absence of multitudes of people, will, of course, be evident on earth. Then, second, after a period of seven years of tribulation on earth, Christ will return to the earth with His church, the saints who were raptured (Matthew 24:30, 2 Thessalonians 1:7, 1 Peter 1:13, Revelation 1:7). He will be victorious over His enemies and will reign on the earth for 1,000 years (the millennium) with His saints, the church.
After 1,000 years, living unbelievers and the wicked dead now raised to life will be judged at the great white throne judgment. They will then be cast into the lake of fire, while the saved will live forever with Christ in a new heaven and earth (Revelation, chapters 19-22).
Many other evangelical Christians believe that Christ’s return and the rapture will not occur until the seven years of the tribulation have ended. As far as the latter view is concerned, the rapture will not be secret, since it will be part of Christ’s visible and triumphant return to end this present evil age (1 Thessalonians 4:13-17).
At this point, interpreters differ as to whether there will be a literal thousand year reign of Christ on earth or whether the white throne judgment and the new heaven and earth will immediately appear.
All Christians do not agree on every detail of what will occur in the final events of this world’s history. Some of these events and their order of occurrence have simply not been made clear in the Bible. What is important is that all Christians hold in common that Christ will ultimately return bodily, visibly, and gloriously to reign and rule with His resurrected and transformed saints forever and ever. The details of this great event will be made known in God’s own time.

Jesus Christ will be seen, and every eye shall behold Him, not only when He comes the second time, but when I send Him for His Awaiting Bride [Elect Harvest workers – Matthew 24:31]. All will know who took their spouses, and parents, and other family members. All will know, My Saints. There is nothing that won‘t be revealed. Father will not tell you how long they will see Him in the clouds meeting you, His Bride, in the air [1st Thes 4:17 – Left Behind]. This is directly in My Word, but has been continuously misconstrued because My Children do not consult Me, as they read My Word. My Saints, the world will be completely deceived by satan and his minions; for he will deceptively say that My Son was an alien come from a distant planet, and the world is going to believe his lying and deceiving ways and persuasions. Every eye will see, but not every eye will believe. It is so important to be in My Holy Word, My Saints.
Matthew 24: 30 Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other.
