...The rapture will occur when He returns for Believers. (Even post-tribs!) This is not a coming...
I believe the rapture is a coming:
"I will come again" (John 14:3).
"The coming of our Lord" (2 Thessalonians 2:1).
"The Son of man coming" (Matthew 24:30).
"The coming of the Lord" (1 Thessalonians 4:15).
"They that are Christ's at his coming" (1 Corinthians 15:23).
I don't believe that the scriptures teach a 3rd coming.
...Christ does not arrive at the earth...
I believe that we will be caught up to meet Jesus coming "in the clouds" on his way down to set his feet on the earth.
"The Son of man coming in the clouds...
with a great sound of a trumpet,
and they shall gather together his elect"
(Matthew 24:30-31).
"We which are alive and remain unto the coming of the Lord...
with the trump of God...
shall be caught up together with them in the clouds, to meet the Lord"
(1 Thessalonians 4:15-17).
I don't believe that the scriptures teach two different comings "in the clouds,"
or two different "last" trumps (1 Corinthians 15:52),
or two different raptures.
Because 1 Thessalonians 4:14-17 shows Jesus "coming," but doesn't show him landing on the earth, some believe it refers to a part-way coming of Jesus whereby he comes down only as far as the clouds and then returns to heaven. But note that Matthew 24:29-31 and Revelation 19 don't show Jesus landing on the earth either. Do some then believe that Matthew 24:29-31 and Revelation 19 are also not the 2nd coming?
Note that 1 Thessalonians 4:14-17 doesn't show Jesus returning to heaven. Acts 1:11 says Jesus will "come" just as he left: he won't come only as far as the clouds and then return to heaven again, just as he didn't leave only as far as the clouds and then return to earth again. He went from the Mount of Olives to the clouds to heaven, he will come from heaven to the clouds to the Mount of Olives (Zechariah 14:4). There's no 3rd coming of Jesus.
...John 14:3 implies that Christ will come to take us to where He is...
Note that no verse says the rapture takes anyone any higher than the clouds.
Jesus said: "I will come again, and receive you unto myself" (John 14:3). Note that he didn't say he would come back before the tribulation or that he would take us into heaven.
Jesus said: "I will come again, and receive you unto myself; that where I am, there ye may be also" (John 14:3). Note that he says we will be where he is after he comes again. He doesn't say he will turn around and go back into heaven. And indeed we will be where he is after he comes again: on the earth during the millennium (Revelation 20:4-6, 5:10, 2:26-29).
I believe Jesus said "In my Father's house are many mansions... I go to prepare a place for you," to show why he was going, not why he was coming back, and to show that he still has great and eternal plans for us in New Jerusalem, where the Father will dwell with us after the millennium: "I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God" (Revelation 21:2-3).
...This return will be FOR His saints as in I Thessalonians 4...
Note that at the rapture Jesus will come back "with" all his saints: "Even so them also which sleep in Jesus will God bring with him" (1 Thessalonians 4:14); "I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ" (1 Thessalonians 5:23), "to the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints" (1 Thessalonians 3:13).
...Then we have the seven year tribulation...
Note that no scripture promises us a rapture before the tribulation. Jesus says he will come to gather us together "immediately after the tribulation" (Matthew 24:29-31), and Paul says Jesus' coming to gather us together must "destroy" the Antichrist (2 Thessalonians 2:1-8). We Christians must go through the coming tribulation (Revelation 13:7-10, 14:12-13).
...the marriage supper of the Lamb...
Note that the Bible doesn't show the marriage of the church or the marriage supper happening before or during the tribulation, or in heaven; it doesn't announce the marriage and supper until the 2nd coming, immediately before we descend with Christ at Armageddon (Revelation 19:7-9, 14). "The bridegroom came; and they that were ready went in with him to the marriage" (Matthew 25:10). I don't believe the Bible teaches a 3rd coming.
After the tribulation, I believe the rapture will gather us into the clouds to be married (Revelation 19:7) before Armageddon. The supper will be on the earth after Armageddon (Revelation 19:9, 17; Isaiah 25:5-9).
Note that the supper on the earth in Isaiah 25:5-9 is spoken of in connection with the same coming in which Jesus "will swallow up death in victory" (Isaiah 25:8); "Then shall be brought to pass the saying that is written, Death is swallowed up in victory" (1 Corinthians 15:54).
In the pre-trib view, why isn't the Lamb at the marriage of the Lamb (Revelation 19:7) or the supper of the Lamb (Revelation 19:9) at any time we see him during the tribulation (Revelation 5:6-13; Revelation 6:1; Revelation 7:9-17; Revelation 14:1-4)?
...Matthew 24 is not speaking of the rapture...
In the pre-trib view, isn't Matthew 24:36-44 speaking of the rapture? Note that in Matthew 24:36-44 Jesus is referring to the same "coming of the Son of man" as when he says "immediately after the tribulation of those days... they shall see the Son of man coming" (Matthew 24:29-30). Jesus isn't teaching a 3rd coming.
...The church is not part of the tribulation...
Note that we Christians are referred to throughout Revelation (6:11, 7:14, 9:4, 12:17, 13:7-10, 14:12-13, 15:2, 16:15, 18:4, 20:4), and there are no Christians outside of the church (Ephesians 4:4-5).
...is not in Matthew 24...
In the pre-trib view, in Matthew 24:36-44, isn't Jesus speaking to us Christians, whether Jew or Gentile? Note that he is speaking to the same believers, the same "ye," in Matthew 24:15 that he is speaking to in Matthew 24:42.
Note that Jesus tells them: "Ye shall be hated of all nations for my name's sake" (Matthew 24:9). Would unbelieving Jews be hated for Jesus' name's sake?
