I have to disagree with that the 6th seal is not pre Tribulation. Matt 24:29-31 and Mark 13:24-27 are not the same event as the 6th seal event. They are two different events.
The sun will be darkened, and the moon will not give its light
When the moon does not give its light it is because the sun has been completely hidden (A planet bocks out the sun?) or is turned completely off there is no light whatsoever. When there is no light from the sun then our moon can’t reflect light.
The sun became black as sackcloth of hair, and the moon became like blood
A blood moon cannot occur when there is no sun. If you have ever been to the SOHO site you can see that sometimes the sun looks black in some places from solar disturbance but when the 6th seal event describes the sun as completely black I think something will cause the sun to go ballistic around the time of a blood moon.

The 6th seal is the first tribulation then “after that tribulation” is Matt 24:29-31 and Mark 13:24-27. The only people that go before the 6th seal is the Philadelphia Church who is promised escape from the hour of trial and all the martyrs from the time of Jesus’ resurrection to now which is why there is such a large crowd in heaven. After these things I looked, and behold, a great multitude which no one could number, of all nations, tribes, peoples, and tongues. All those martyrs went through great tribulation.
Then the rapture of Daniel 12 when everyone who calls upon the name of the Lord will be saved, the manchild who is taken up in Rev 12. Which is mid trib. The year of 2014
2nd Thess The falling away comes first, and the man of sin is revealed, the son of perdition The word falling away is Greek 646 Apostasia: Defection from truth, falling away, something separative, divorce, to remove. So many argue that it means falling away from the faith or departure. God knew what He was doing in using that word because when only the Philadelphia church is taken in the first rapture many peoples faith will be shaken and there will be a falling away! Both a falling away and a removal will take place at the same time.
God Bless! Thank you John!!
