There are also multitudes saved in that time. Not just the Jews from the 12 tribes. As for placing the church in heaven, if we call the Bride the church, that is correct. There are also plenty of saved people back on earth in that time. So if you want to call them 'Adam's flesh', well there are plenty left behind at the Rapture. Then you claim the church is here till the sixth seal. Proof?
Those remaining will live on the earth. In Matthew 25 the sheep are never said to die, yet they have to be changed out of Adam's flesh and blood. It states they are granted eternal life. That life is on earth.
"Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:"
This is not a judgment placed on the church in Paradise. This is about those Christ as Prince on earth in Jerusalem just pronounced on those on earth after the Second Coming. Jesus never says, oh, but you have to suffer physically and be killed or suffer until the tribulation is over. No where does it claim they have to die or be physically resurrected. They are safe until the Resurrection in Revelation 20:4, where they join those beheaded to live on earth.
The next group are those still alive in the 7 Thunders, but we know little about them except they are the wheat and tares in Matthew 13. But that harvest Jesus explains He and the angels are present on earth at that point. That would be after the Second Coming.
"He answered and said unto them, He that soweth the good seed is the
Son of man; The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; The enemy that sowed them is the devil;
the harvest is the end of the world; and the reapers are the angels."
This happens at the 6th Seal, because that is when the angels and Christ arrive. Revelation 6:13
"And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind."
This is John's symbolism about the angels:
"And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other."
