ABSOLUTE SCRIPTURAL PROOF OF A TWO-STAGE TRIBULATION........

In His 'Olivet Discourse ' Jesus said, "Immediately AFTER the tribulation  'OF THOSE DAYS' ......" in ( Matthew 24:29 ), and then He went on  to describe the events of the resurrection / rapture ot His Body of Christ Church  in ( Matthew 24:30=31 ).  Because the Church is "NOT appointed to wrath" , and because the resurrection  / rapture of the Church is a PRE-TRIBULATION  event  Jesus IS NOT describing the GREAT TRIBULATION upon the whole world in ( Matthew 24:29 ) ,  but rather He IS DESCRIBING the "SHORTENED"  FIRST STAGE of the tribulation exclusively upon Israel that is the GOG-MAGOG WAR.  

To correctly understand  what Jesus means by "the tribulation  OF THOSE DAYS" you must understand that Jesus is speaking "OF THOSE DAYS" of the "shortened" tribulation  judgment exclusively upon the Nation of Israel , which occurs immediately BEFORE the resurrection  / rapture of His Church.  When Jesus said,  "OF THOSE DAYS" He  IS NOT speaking of the days of GREAT TRIBULATION  judgment which comes UPON THE WHOLE WORLD AFTER the resurrection / rapture of His Body of  Christ Church. 

When Jesus said, "AFTER the tribulation  OF THOSE DAYS" in ( Matthew 24:29 ) Jesus means the Church is resurrected / raptured AFTER "THOSE DAYS" of the Gog-Magog War tribulation which is exclusively against Israel BEFORE the rapture. The following Scripture tells us that the tribulation ABSOLUTELY comes IN TWO STAGES according to :

Romans 2:9  ( King James Bible )

"TRIBULATION upon every soul of man that does evil, THEJEWS FIRST and then also THE GENTILES." 

Romans 2:9 ( Pure Word Bible )

"Affliction and distress ( tribulation ) upon every soul of man that produces evil work, BOTH the JEWS FIRST of all, and then also the GENTILES."

SO, THERE YOU HAVE IT :

 The tribulation absolutely comes in TWO STAGES : The FIRST STAGE is  "the tribulation OF THOSE DAYS" which are  upon "the Jews FIRST" that are THE DAYS of the  GOG-MAGOG WAR of tribulation judgment exclusively upon "the JEWS FIRST " in the Nation  of Israel  BEFORE THE RAPTURE.  

Then "IMMEDIATELY AFTER the tribulation OF THOSE DAYS", which are exclusively upon "the JEWS FIRST", the Body of Christ Church is resurrected / raptured according to Matthew 24:29-31, 

Then SECONDLY , AFTER THE RAPTURE God brings the GREAT TRIBULATION  judgment upon THE WHOLE WORLD of the GENTILES. 

Therefore, the Gog-Magog War exclusively upon  Israel is the NEXT EVENT for us to watch for BEFORE the rapture happens according to :

Luke 21:28

"When these things ( the Gog-Magog War ) BEGIN to happen, look up  and lift  up your heads because YOUR REDEMPTION ( RAPTURE ) DRAWS NEAR ." 

The events described previously in Luke 21:20-27 are the events of the Gog-Magog War of tribulation exclusively upon "THE JEWS FIRST"  BEFORE THE RAPTURE. 

According to Your Holy Word, come Lord Jesus !
