THE GREAT TRIBULATION BEGINS WHEN JESUS OPENS THE SEVENTH SEAL.....

Jesus opens the SEVENTH SEAL and gives the SEVEN  ANGELS the SEVEN TRUMPETS  of judgment. The GREAT TRIBULATION BEGINS when the FIRST ANGEL SOUNDS his trumpet , and the Great Tribulation ends after the seventh angel  sounds his trumpet.

Previous to Jesus opening the Seventh  Seal,  which BEGINS the Great Tribulation ,  the LAST EVENT of the SIXTH SEAL is the resurrection  / rapture of His Body of Christ Church who are now the GREAT MULTITUDE IN HEAVEN standing  before the Lamb BEFORE the Seventh Seal is opened.  

AFTER the resurrection / rapture event of the SIXTH SEAL is complete Jesus then opens the SEVENTH SEAL and God's Great Tribulation judgment BEGINS upon the WHOLE WORLD  with the SEVEN ANGEL'S trumpet judgments . The Great Tribulation upon  the WHOLE WORLD   BEGINS when the FIRST ANGEL sounds his trumpet according to :

Revelation 8;1-2

"And when He had opened the SEVENTH SEAL there was silence in heaven for about the space of half an hour. And I saw the SEVEN ANGELS which stood before God  , and to them were given SEVEN TRUMPETS."

NOW NOTICE that John sees the GREAT MULTITUDE IN HEAVEN as the LAST EVENT of the SIXTH SEAL BEFORE Jesus opens the SEVENTH SEAL which then BEGINS THE GREAT TRIBULATION .

Scripture states that the GREAT MULTITUDE are in heaven  BEFORE the Great Tribulation BEGINS. Therefore, the GREAT MULTITUDE in heaven CANNOT BE TRIBULATION SAINTS. 

SO, THERE YOU HAVE IT :

The GREAT MULTITUDE IN HEAVEN , which is the last event of SEAL SIX , who are before throne and before the Lamb  CAN BE NONE OTHER THAN the resurrected  / raptured Body of Christ Church who are raptured TO HEAVEN BEFORE the Great Tribulation BEGINS when Jesus opens the SEVENTH SEAL thus proving the rapture is PRE-TRIBULATION.  The events of seal #1 through seal  #7 are given to us in chronological order of occurrence. That is why they are numbered for us so we can know the exact order of occurrence. 

The tribulation saints CANNOT APPEAR in heaven as part of the SIXTH SEAL BEFORE the tribulation  BEGINS when Jesus opens the SEVENTH SEAL !  The GREAT MULTITUDE IN HEAVEN , described in Revelation  7:9-17, is THE RESURRECTED / RAPTURED BODY OF  CHRIST CHURCH . The tribulation saints come in later AFTER the Great Tribulation BEGINS. 

According to Your Holy Word , come Lord Jesus !
