THE QUESTION  IS ASKED .........

The question is asked in :

 Revelation 6:17

"For the great day of His wrath is come , and WHO SHALL BE ABLE TO STAND ?"

The question  is answered in:

Revelation 7:9

"After this I beheld , and lo, a great multitude which no man could number of all nations and kindreds  , and people, and tongues  STOOD  BEFORE THE THRONE and  before the Lamb ."

SO, THERE YOU HAVE IT:

No one CAN STAND  before the throne and before the Lamb  in heaven without first  being resurrected and/or raptured . The "great multitude" in heaven STANDING before the throne and  before the Lamb  is the resurrected/raptured Body of Christ Church. 

According to Your Holy Word, come Lord Jesus !
