Ola you stateThey thus in error conclude that they must be the saints that will be killed in the Great Tribulation, for their faith in Christ.I disagree with this thought simply because, the angel doesn't say to John that they were killed for their faith.He only says,
"These are they which came out of Great Tribulation..." (Rev.7:14)Really Ola? Rev 6:9And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held
Rev 6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? Rev 6:11
And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they [were], should be fulfilled.
Note; this is in keeping with "until the fullness of the Gentiles comes in" There is a certain number.
Now in chapter 7
It is asked who is this multitude? Elders represent the raptured Church and are asking the question
And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?
Rev 7:14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
