The End will come after the Rapture. I believe the following verses is what happens at the beginning or right after the rapture: “I looked when He opened the sixth seal, and behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind. Then the sky receded as a scroll when it is rolled up, and every mountain and island was moved out of its place. And the kings of the earth, the great men, the rich men, the commanders, the mighty men, every slave and every free man, hid themselves in the caves and in the rocks of the mountains,”“and said to the mountains and rocks, “Fall on us and hide us from the face of Him who sits on the throne and from the wrath of the Lamb! For the great day of His wrath has come, and who is able to stand?”
Revelation 6:12-17NKJV
So, the Bible is stating this is the day of God’s wrath. Just before this verse it states what tradition says the disciples and other Christians went through in history after Jesus went to heaven, they were persecuted and killed. Matthew 24 and Luke 21 state the timeline of the world until the tribulation and the second coming of Christ. The second coming of Christ is different from the rapture as stated in Titus when Paul calls the coming of Christ an appearing and kingdom. The rapture could be called an appearing. When Christ returns to the earth it will be his kingdom being set up. I highly recommend a book by Bob Yandian called Understanding the End Times. I believe it is quite accurate. Anyway, Luke 21 says this: “But before all these things, they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons. You will be brought before kings and rulers for My name’s sake.”
Luke 21:12 NKJV
I believe this has already happened and does not apply to our time because it says before all these things. Matthew 24 verses 9-10 says what I don’t think applies to us because with Luke 21 it says before all these things. What it says before this is what we look for as signs for our time: “And there will be great earthquakes in various places, and famines and pestilences; and there will be fearful sights and great signs from heaven.”
Luke 21:11 NKJV
Also this is another sign for our time: “Then many false prophets will rise up and deceive many. And because lawlessness will abound, the love of many will grow cold.”
Matthew 24:11-12 NKJV
Finally Matthew chapter 24 verses 15-28 talk about the tribulation as does 1&2 Thessalonians and Revelation. So to conclude the rapture can’t take place until the Son of Perdition is revealed or the Antichrist. “Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition,”
II Thessalonians 2:3 NKJV
When we see the Son of perdition who exalts himself above all that is called God, the rapture will take place and the end will come.
