"Question 1: Show me the rapture mentioned in Revelation 19:11-21 or Zechariah 14:1-5? It’s not there."
I don't use the word "rapture", neither does God's Word. Rapture comes from a Latin translation of the Greek word harpazo ("caught up" in the KJV). So from the start, dispel any and all "rapture" theory usages.
Revelation 19:2 Jesus has avenged His saints; Rev.19:7-9 the marriage of The Lamb, and those called to it, which per Matt.25 is when Jesus returns.
3 Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle.
4 And His feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
5 And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the LORD my God shall come, and all the saints with Thee.
Parallel proof that the Mount of Olives is where Jesus will literally return to is in Acts 1, showing where He ascended to Heaven from, and the angels revealing that He would return in like manner.
"Question 2: Show me the church mentioned in one OT or NT passage discussing the tribulation?"
3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
Jesus then explained to them what would befall His Church at the end of this world just prior to His return to gather them, since the very last sign He gave in that Olivet Discourse was the sign of His Second Coming.
In 2 Thess.2 Apostle Paul covered signs of the future tribulation at the end of this world. Apostle John was given the Revelation by Jesus, and it covers many signs of the very end of this world which parallel His Olivet Discourse signs? Ever read it???
"Question 3: How can the rapture and glorious appearing be on the same day when the rapture day is unknown and the glorious appearing day will be known? How can a day be both known and unknown?"
The misunderstanding is your own fault; trying to apply absolutism dating to an unknown day. If someone says, "on that day", it means a certain and specific day, but it doesn't define the exact date like October 22, 19.... Christ's return will be on a specific day, and hour, but like He said no man knows what 'date' that is. Yet He did... give His to know events leading up to that day, and that's for His that believe and watch, staying in His Word of Truth.
Question 4: The open door into heaven with a voice, trumpet, and catching up to heaven occurs in both Rev 4:1 and I Thess 4:16-18.Why do post-tribs reject this as the pre-trib. rapture? Open door Rev 19:11.
If one continues to read Rev.4:2, should notice that John said he was "in the spirit" when that happened. There's Old Testament examples of that also, like Isaiah 6. Ever read it? Or Ezekiel 8. Ever read it? If you had, you wouldn't have allow those without knowledge to misguide you to think Rev.4:1 is about a rapture. John's flesh body was simply in prison on Patmos while his spirit was shown the Revelation visions.
In Rev.19:11, Heaven is opening with Jesus Christ coming on His white horse, with a sword. No "rapture" idea there at all.
"Q5: If you accept the 2 witnesses are caught up to heaven in Rev 11:12 by ‘Come up hither’ why not rapture in 4:1?"
Because Rev.11:12 specifically is... about the final 7th Trumpet ("last trump") being changed and caught up to the Heavenly at the end of this world per Christ's Promises, while Rev.4:1 is about John being in prison on Patmos with God touching John's spirit to see visions. Same thing in Ezekiel 8 when Ezekiel was shown by God visions in the temple.
"Question 6: Show me the church on earth from Revelation 6-18? It is not there because it is in heaven."
15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
16 And He gathered them together into a place called in the Hebrew tongue Armageddon.
17 And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.
Where is it taught in the NT that Jesus will come "as a thief in the night"? By Apostle Paul in 1 Thess.5, right after he had mentioned being "caught up" by Jesus in 1 Thess.4. Jesus is speaking DIRECTLY TO HIS CHURCH ON THE 6TH VIAL timing. He is warning His Church that is ON EARTH, to keep their garments lest they walk naked and in shame. In Rev.3 Jesus spoke to the Church at Sardis about defiled garments.
So there you have it, Biblical proof... that Christ's Church is STILL... on this earth all the way through the 6th Vial.
"Question 7: If the church is not raptured until Rev 20:4, as post-tribulationists think, then how could the church be in heaven in Rev 19:7-11, before Christ’s glorious appearing?"
Even a true pre-tribber ought to be embarrassed to ask this question. Apostle Paul in 1 Thess.4 showed us clearly that when our Lord Jesus comes, He will bring the "asleep" saints WITH HIM...
1 Thess 4:14-15
14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
That means those who have already died in Christ, those Jesus will raise and bring with Him when He comes back to the Mount of Olives.
This shows how pre-trib confuses the "asleep" saints today with their false pre-trib rapture view.
"Question 8: Do you agree that the 24 elders in heaven represent the raptured church age Christians?
If no, then who are they and what proof do you have of their identity?
If yes, then will you accept the pre-tribulation rapture and reject the post-tribulation rapture as error?"
I don't use the word "rapture" since The Bible doesn't either. I use "caught up" from the KJV translation of Greek harpazo. The 24 elders of Rev.4 & 5 is a post-tribulation millennial VIEW. It's a future-forward VISION John was given. Not everything John was given by vision in Revelation was in the exact order it will occur. This also is how the Old Testament prophets are written. This is why men who devise theories like the pre-trib rapture theory (began in 1830 in Britain through John Darby) show they have MUCH lacking in Old Testament Book study, especially the prophets. Apostle Peter told us to be mindful also of what is written in the prophets (2 Pet.3:2).
"Question 9: Do you agree that the armies in fine linen accompanying Christ at His return are church age Christians? If no, then who are they and what proof do you have of their identity?"
I agree they are all... believers and followers of Jesus Christ. If you left out Abraham then you'd be denying the first origins of faith on God's Promised Salvation by Faith (Galatians 3). The phrase "church age", how it's used today can be a trap into all sorts of non-Biblical doctrines of men.
"Question 10: Who are you looking for, Christ or antichrist? Why would Christ want His bride to look for the antichrist?"
Those who remain faithful to the end, waiting on Christ Jesus to return like the prophecy states, look for the coming Antichrist who will come first and cause great tribulation upon the saints still alive on earth, and then we look for Jesus Christ to return and defeat the Antichrist and gather us to Him and the asleep saints He brings with Him, which will end the tribulation. To refuse the warnings our Lord Jesus and His Apostles gave His Church today about the coming Antichrist is a sign of rebellion against Christ Jesus, and thus that rebellious one will not remain a "chaste virgin" to Jesus when He comes later.
"Question 11: How will the tribulation sufferings comfort us? Post-tribulationists can’t explain this."
No suffering comforts us. The Holy Spirit Comforter Jesus sent comforts us. Our Lord Jesus' grace and forgiveness when we sin and repent comforts us, for all men fall short of the glory of God. So your idea is kind of... sick, as you're trying to fit a square peg into a round hole with a very un-Biblical analogy.
"Question 12: Does the Philadelphian church represent the faithful church at the end of the church age?
Do you believe that God will keep this church out of the time of the tribulation coming on all the world?"
Only 2 Churches in Rev.3 & 4 our Lord Jesus had no problems with, Smyrna and Philadelphia. They represent His elect saints. And what did He warn His very elect saints about in His Olivet Discourse of Matt.24:23-26, which is about the time of great tribulation? Why would Jesus warn His very elect of that for that tribulation timing if they are to be raptured like the false pre-trib rapture theory of man proposes? Simply because the pre-trib rapture theory is false, a doctrine of men.
"Question 13: Since Jesus returns to earth from a wedding, doesn’t this prove the church is in heaven before the glorious appearing? Can you see that this disproves the post-tribulation rapture? Why is the church in heaven (19:7) if the church is raptured after Jesus returns to earth as post-trib claims?
You obviously cannot read. Rev.19:2, He has already... judged the whore. Rev.19 is about Christ's second coming to judge the whore. Rev.19:7-14 are about the armies of the "asleep" saints Paul said Jesus will bring with Him when He comes!
Have your pre-trib teachers not taken time to explain to you that 1 Thess.4 is covering TWO GROUPS of saints, and not just one??? The first group are the saints that "sleep" in Jesus that have already died. The 2nd group are the alive saints on earth that are "caught up" to Jesus AND THEM, when He comes! The only saints who are to be "caught up" are the ALIVE saints on earth when Jesus returns to end the tribulation!
What they refuse to teach you is how THAT 1 Thess.4 scripture by Apostle Paul is showing that time of the alive saints on earth being "caught up" is the SAME... timing of the future resurrection of the saints.
"Question 14: Who is the Restrainer? If he is the Holy Spirit’s influence in the church, then doesn’t this prove the rapture comes before antichrist is revealed and before the tribulation as II Thess. 2:6-8 states?"
The one who holds of 2 Thess.2 that Paul mentioned is in Daniel 10. It is NOT... The Holy Spirit. You are presenting just another false doctrine of men, and idea from hirelings that don't understand The Word of God.
2 Thess.2 is specific... that the Antichrist will come first to cause a great apostacy, and then Jesus will come to destroy him with the brightness of His coming. THAT... is when the Antichrist will be 'revealed' to the deceived. When Antichrist first shows up THAT... is when he will be 'revealed' to Christ's elect and not the deceived. Those deceived will not know who that Antichrist really will be until Jesus returns, and thus their shame for flying away to that false one who comes first. That is exactly what pre-trib rapture theory is for, to deceive as many as will listen to men, instead of God through His Son by His Word of Truth.
"Question 15: Why would Jesus prepare a place for us in heaven and not take us there at the rapture (as post-tribulation rapture people think)?"
This so simple, if people would only read what our Lord Jesus said in John 14, even this:
3 And if I go and prepare a place for you, I will come again, and receive you unto Myself; that where I am, there ye may be also.
Where is our Lord Jesus coming to per Scripture at His 2nd coming? To the Mount of Olives (Acts 1; Zechariah 14). That is where He is indirectly referring to. So what did the Old Testament prophets reveal about that? They revealed there will be a sanctuary complex built by Jesus there in Jerusalem (Zechariah and Ezekiel). That complex will contain 'abodes' for the priests. And that's actually what the word "mansions" in John 14 means, abodes. On earth is where the prophets show that will take place.
"Question 16: What is the purpose of the rapture if it occurs at the end of the tribulation? No purpose!"
That shows how in love one can be with a doctrine of man. Apostle Paul compared that kind of deception to men's doctrines as being spiritually "drunken" (1 Thess.5). The "caught up" idea of 1 Thess.4 is only about the saints still alive on earth to the very LAST DAY of this present world:
40 And this is the will of Him That sent Me, that every one which seeth the Son, and believeth on Him, may have everlasting life: and I will raise him up at the last day.
The resurrection of the saints AND the "caught up" event occur BOTH ON THE SAME DAY, THE LAST DAY. The last day means the END of this present world, i.e., NO MORE WICKED REIGNING ON EARTH!
"Question 17: Who resurrects and gathers the church at the rapture, Christ or angels? Christ! Then how can Matthew 24:31 refer to the rapture if angels gather the elect of Israel here?"
Here you've made the same mistake again. You agree the resurrection of the "caught up" event both happen at the same time by that. But when does Scripture show the resurrection happens??? On the LAST DAY... which Jesus showed in the above Scripture I quoted from John 6:40. You can also find it in John 6:39; John 6:44; John 6:54; John 11:24; and John 12:48 reveals the wicked being judged on that same "last day".
Shall I keep going???
