I'm a bit confused by your answer. You seem to suggest that in Rev. 7:9-17 there are two different groups mentioned.
According to the passage, however, the vast multitude which cannot be numbered are those that have come out of the great tribulation. Vss 13,14 one of elders asks - who are these in the white robes? and he answers that they have come out of the great tribulation. They are before the throne of God. vs 16 They shall hunger no more, neither thirst any more..." and vs 17 "...and God shall wipe away every tear from their eyes." It also seems that they will no longer be touched by sin or death.
Perhaps you can clarify that for me.
I certainly did not intend to imply two groups, sorry.
For now, Rev 7:9-17 is one group a great multitude which no one could count,...who come out of the (30) great tribulation...and (42) God will wipe every tear from their eyes." These are the raptured saints, in my pre-wrath rapture viewpoint.
