How about giving us clear Scripture to show this? Where in Scripture does it say, "there will be believers who get left behind, that wasn't chosen as a Bride, but they are still saved"? You cannot even prove there is a tribulation period after the second coming.
When Jesus comes, He rescues all the elect and destroys all the wicked, before He pours out is final and wholesale wrath. That is the pattern of history. That is what Scripture teaches.
Where does it say the one left behind is (a) believer and (2) survives the wrath that is poured out in that great climactic day? You are forcing what you have been taught into the inspired text. You have to. There is not one single proof text in the Word. Your failure to provide the same reinforces that. No Pretrib can prove that. All we are getting from you is wild unsubstantiated claims.
If you were to openly and objectively look at the text that you are referring to, you would see that it actually forbids a Pretrib scenario. Good at the proves Amillennialism. Instead of the Pretrib soundbites, let us look at what the text actually says!
Jesus said in Luke 17:24-34: “For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day. But first must he suffer many things, and be rejected of this generation. And as it was in the days of Noe, so shall it be also in the days of the Son of man. They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all. Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. Even thus shall it be in the day when the Son of man is revealed. 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. Remember Lot's wife. Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it. 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. Two women shall be grinding together; the one shall be taken, and the other left. Two men shall be in the field; the one shall be taken, and the other left. 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.”
“one shall taken, and the other shall be left”
If we look closer at this passage we learn, “in that night (when He shall Come) there shall be two in one bed; the one shall be paraleemftheésetai (or) taken, and the other shall be afetheésetai (or) left. Two women shall be grinding together; the one shall be paraleemftheésetai (or) taken, and the other afetheésetai (or) left.”
It is interesting when we look at the meaning of this Greek word paraleemftheésetai used here. Strong’s says that it indicates, “to receive near, i.e. associate with oneself in any familiar or intimate act or relation.” The word is interpreted elsewhere in the King James Version as ‘receive’, ‘take unto’ or ‘take with’. The company that are therefore received by Christ in this passage are those that have been brought into an intimate mystical union with Him through salvation; they are His elect. This narrative is unquestionably referring to the catching away of the saints, and the marriage of the lamb.
This is the same word that Christ used in John 14:3 when He promised His disciples that He would come again to receive them, saying, “In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and paraleémpsomai (or) receive you unto myself; that where I am, there ye may be also.”
Interestingly, the word used here to describe the second party in view is the Greek word afetheésetai, which carries the meaning to forsake, put away or lay aside. This is the fate that awaits the wicked alone when Christ comes in all His glory.
No one that has taken the time to examine the meaning of the Greek words for “taken” and “left” can surely deny that the definition of “taken” is manifestly positive and the definition of “left” is patently negative.
Q. What then happens to those left behind?
A. The Lord’s solemn warning in the midst of the aforementioned narrative confirms the answer, and is in complete agreement with Christ’s unambiguous preceding comments in the same chapter, and every other explicit passage in Scripture. He makes it abundantly clear that instant and complete destruction befalls the wicked. He solemnly counsels the disciples, “Remember Lot's wife.”
Remember Lot's
Q. Why must we “remember Lot's wife”? What befell her?
She got caught in the escape out of Sodom because her heart was still there. Despite being fully aware of the impending destruction, Lot's wife’s heart was located in Sodom and towards the awful iniquity; this was despite the fact that she also desired to be with the people of God. Notwithstanding, Genesis 19:26 says of Lot, “his wife looked back from behind him, and she became a pillar of salt.”
Her foolish refusal to once-and-for-all turn her back on Sodom caused her to be instantly and completely destroyed. Through her un-preparedness, she was immediately cast into a lost hell – damned and doomed for all eternity – without hope and without Christ.
What Christ is therefore warning in this reading is this: ‘Remember Lot's wife because she was found wanting on the day when God finally poured out His judgment upon the wicked; be warned because His second coming will similarly expose the heart of every hypocrite, although on this occasion it will be for the very final time. Those left behind will face the same punishment as Lot’s wife – total destruction.
When Noah left the world of his day and entered into the ark
there were many left lying in beds and grinding at mills to receive
the wrath of God and therefore destruction. The same happened in Lot's day. The same will happen at Christ's Coming.
After Christ described the destruction that accompanies His return, He talks about one being rescued the other being destroyed. Jesus tells us that those left behind will suffer the same total, immediate and awful doom that Noah's world and Sodom suffered in their day (Luke 17). Once the ark door closes that is it. It is too late.
Where ever the carcass is there the eagles will be gathered together
The disciples then ask: “Where, Lord?” Christ replies: “Wheresoever the body is, thither will the eagles be gathered together.” Eagles flock to where there is prey. Where bodies lie that is where they will congregate. Death and destruction mark the aftermath of God’s judgment. Whilst God’s people are rescued the wicked perish in destruction.
The eagles devour those left behind. Rev 19 correlates.
