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 Lamb, clothed with white robes, and palms in their hands;"
This is after John's second vision has taken place. Only here, and in John 12:13 were palms used to glorify our Lord. The Jews used these palm branches, "and cried Hosanna: Blessed is the King of Israel that cometh in the name of the Lord". That is a fact, Jesus did come in the name of the Lord God Almighty.
Revelation 7:10 "And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb."
In other words, these great numbers of people, came from all races and nations and languages on the face of the earth, and each and every one of them have been saved.
This is not part of the "rapture" as many teachers teach. No; but it is the people who have died in the Lord's work, and have gone to be with Him. It is my father who died twelve years age, and my uncle Ron who has passed on; It's my grandmother Knecht, who passed on when I was a child, and every other saint of God, who lived a life on this earth, and died and went to be with the Lord; from any century in this earth age.
Those are the ones John sees standing before the Lord in their white robes, washed in the blood of the Lamb, and their sins made white as snow.
Though we laid their fleshly bodies in the ground, Praise God their souls went immediately to be with the Father. [Ecclesiastes 12:7] From Adam and Eve to this present time, all these saints of God are now angelic soul beings; though they sinned in the flesh, each has repented of their sins, and God is faithful and just to forgive all those sins, and make them white and pure as snow.
These are the people Christ brings with Him ,they got to Heaven when they died,why is that so hard to understand?
