This is going to be a short teaching on the rapture. It will not be a popular teaching because the flesh doesn't want to hear the truth. The church teaches for the most part that it will be taken out "Raptured" before the start of the tribulation. Question is, what does the Word say about the timing of the"Rapture"? Let's start with Yeshua and His disciples in Mathew Chapter 24. Here we see His disciples asking Him what to look for at His 2nd comming. What I would like to do is compare the text of Math. Ch24 and Rev. Ch.6&7
Mathew

1. There will be a rise in false Christ. V(5) seal1
2. There would be a rise in wars between nations.  V(6) seal2
3.  There will be famines, pestilence, and earthquakes in diver places.  V(7) seal3&4
4. The Antichrist would desecrate the temple of GOD.  V(15) seal5
5. There would be a period of severe tribulation for GOD’s people. V(21) seal5
6. Sun darkened and moon will not give light V(29) seal6

 When we compare these signs to the seal judgements, we see that they are one and the same. Revelation chapter 6
 

1. Wars and Rumors of war. False christ’s Rev 6. 1-2: seal 1
2. Nation will rise against nation and kingdom against kingdom.  V(4) seal 2
3. Famines, pestilences, and earthquakes in diver places V(5-8) seal 3 and 4
4. Severe tribulation V(9-11) seal5
5. The sun became black as sackcloth of hair, and the moon became as blood; V(12)seal6
6. The 4 winds V(7:1) before 7th seal
7. These came out of the Great tribulation V(7:14)

     Notice the 4 winds are mentioned in Math. 24:31 and Rev. 7:1

24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.

Matthew 24:31

Now Revelation 7

7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.

Revelation 7:1

Let's compare  Rev. 7:14  and Math 24:21 these verses both talk about the great tribulation.

24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

Matthew 24:21

7:14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.

Revelation 7:14

The Great Tribulation starts when the Antichrist stands in the temple and declares he is god.  The entire seal judgments trumpet and bowl judgments are not the great tribulation as taught in pre-rapture doctrine. The great tribulation starts at the 5^th seal thru sometime after the 6^th seal. Note: The seals are not G-D’s wrath. They are not for punishing the world, but for evangelizing it. They are also a time of refining fire for the church. It is the Antichrist wrath upon man.
Hope you can start to see that we will be around for some hard times. Will finish in part 2
