"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, clothed with white robes, and palms in their hands;" Rev. 7:9.
Through this verse we have a tremendous insight into the tribulation period. Insight into what Satan is doing and insight into what God is doing. When the tribulation period begins there are no believers on the earth, the church has been raptured leaving no saved people on earth. Though we do not have much information about the details of what God is doing, as Satan works to corrupt men, and to destroy and enslave, God is also at work, the gospel is preached and multiplied millions are saved. That is a revelation about the tribulation period that we seem to forget. Perhaps more people are saved than in all of the past ages of history. Here in verse 9-12, we see them around the throne in heaven, during the tribulation period, worshipping God and praising Him.
These verses give us a rare glimpse into heaven, these verses are some of the most revealing in all of scripture concerning heaven.
Verses 13,14 confirm who these are, emphsis is on the salvation of these saints. "These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb" verse 14. The question in verse 13 is answered, "whence came they?"
As we study through the book of Revelation and are overwhelmed by the awful rebellion of man and the catastrophic judgment of God, we need to have superimposed upon our minds Rev.7:9-14. Remember, there are two scenarios in the book, that which Satan is doing and that which God is doing. The plan of Satan comes to a climax and the plan of God comes to fruition.
The tribulation martyrs seem to be on the losing side, perhaps you sometimes feel you are on the losing side, read and reread these verses.
But rejoice, inasmuch as ye are partakers of Christ`s suffering`s; that, when His glory shall be revealed, ye may be glad also with exceeding joy. 1Pet.4:13
