If the Church is raptured at the end of the Tribulation then there are no physical believers left to populate the world and produce the offspring that is killed just prior to the Great White Throne Judgment:
Revelation 20:7-9 King James Version
7 And when the thousand years are expired, Satan shall be loosed out of his prison,
8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
Secondly, the "Sheep" of the Sheep and Goat judgment are not glorified, but are "left:"
Luke 17:26-37 King James Version
26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
30 Even thus shall it be in the day when the Son of man is revealed.
31 In that day, he which shall be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
32 Remember Lot's wife.
33 Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it.
34 I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
35 Two women shall be grinding together; the one shall be taken, and the other left.
36 Two men shall be in the field; the one shall be taken, and the other left.
37 And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
When the Son of Man Returns, according to His Own Word, we will see complete destruction of the wicked, as it was in the days of Noah and Lot.
He destroyed them all.
One shall be taken, and one left. Where are they taken? He just told you: they are taken in judgment. They are destroyed.
Hence the Supper of the Great God.
If we interpret Prophecy as it has always been interpreted it is really very easy to understand. But when we try to make Scripture something other than what it is, revelation provided to men that we might know the Lord's will and what is going to happen, then we end up stumbling over our doctrine.
Like you and other Post-Tribulational believers do.
