“After this I looked, and there was a vast multitude from every nation, tribe, people, and language, which no one could number, standing before the throne and before the Lamb. They were robed in white with palm branches in their hands.
Then one of the elders asked me, "Who are these people robed in white, and where did they come from?"
I said to him, "Sir, you know."
Then he told me:
These are the ones coming out of the great tribulation.
They washed their robes and made them white
in the blood of the Lamb.”
When the "Great Tribulation" happens there will be those from every nation, tribe, people, and language who will come out of it and stand before the throne and before the Lamb.
This is a word of great encouragement for every believer to remain faithful to Jesus no matter what is happening around you. Even if it looks like you have found yourself right in the middle of the "Great Tribulation" remember there will be a "vast multitude" which will come out of that tribulation and stand before the Throne of God!
Interestingly enough these verses do not indicate that they will get out of that terrible situation by dying. Verse 16 of this chapter mentions what they will no longer suffer. Death is not mentioned. The implication seems to be that they came to the throne room without dying on this earth. Like Enoch they pass from this earth without walking through the door of death.
If you are a follower of Jesus Christ today then look up, stand up, speak up, because "soon oh very soon" you may go up to praise Him in His presence!
