Please let me show you something.
Those Jews who came to Jesus during the Trib are presented, by their tribes:
Revelation 7:8
“Of the tribe of Zabulon were sealed twelve thousand. Of the tribe of Joseph were sealed twelve thousand. Of the tribe of Benjamin were sealed twelve thousand.”
Those are the Jews who came out of the Tribulation Period. There is then another group presented:
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 throne, and before the Lamb, clothed with white robes, and palms in their hands;”
This group is the sum of all who were prepared with their lamps trimmed and burning at the time of the Rapture.
Both groups receive white robes in Heaven and return to earth with Jesus at the time of His Second Coming. This is not new. It has been right there in your Bible for the longest time.
