Rev. 1 has two parts, this is gross misinterpretation.
7 Behold , he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
Clearly a picture of the Second coming, but we don't have the loud voice and trumpet linked to this! Verse 8 ends John's intro to the book, then he explains his first vision by referencing a voice and trumpet. He then sees the picture of Jesus as He's described with the message to the seven churches. Notice the Amens at the end of verses 6 and 7. Each of theses are completed statements.
What is interesting is that when John sees the vision of Jesus there is a loud voice like a trumpet, but we can't definitively link v. 8 with the rest of the vision of chapter one. This is a vision that compelled John to write the book of Revelation, it's not a vision of what the Second Coming is! How can you say this?
2 Who bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
Again you misunderstand. John is not saying he definitively sees "all things that will happen." Everything that he sees is definitively the word of God and of the testimony of Jesus christ. John's vision is the fullest account of the future, but it is not everything that will take place.
I believe there are clear allusions to the Rapture in the picture of saints being in heaven, the promise of "kept from the hour (the very time period) of tribulation that will come upon the whole earth" and the illustrative nature of the beginning of chapter 4, where John is taken to heaven "after these things." What things? After the message to the seven churches, the dispensation of the Church. I'm not going to force the Rapture into chapter four, but I think there is a natural picture of it.
Let's review 1 Thessalonians. The first three chapters are personal and historical, about Paul and his relationship to the Thessalonians and their growth. Then 4:1
1Finally then, brethren, we request and exhort you in the Lord Jesus, that as you received from us
instruction as to how you ought to walk and please God (just as you actually do walk), that you excel still more.
This begins a section that goes thru verse 8.
Verse 9 is a new topic:
9Now as to the love of the brethren, you have no need for
anyone to write to you
Paul introduces this with the Greek words
Peri de, now concerning. This goes thru verse 12
Verse 13, new topic, again with the Greek word
peri, concerning those who are asleep in Jesus, this goes thru verse 18.
Now notice again, ch. 5:1, new topic, again introduced with
peri de, Now concerning the times and epochs, the day of the Lord. This is a clear linguistic and topical break that is not based on a chapter division, it's based on the Greek text!
Pre-trib theorists are not trying to make up what isn't there. We are reading the clear breaks that Paul is making in his discussion.
The restrainer is removed before the man of lawlessness is revealed. This must be before he opposes and exalts himself above every so-called God. In other words, it must be before the mid-point of the tribulation. In fact the Restrainer is removed before the lawless one is even revealed! So before the beginning of the Tribulation, Daniel's 70th week! I'm not making this stuff up!
Then notice Paul's concluding remarks.
2 thess 2:13But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation through sanctification by the Spirit and faith in the truth.
14It was for this He called you through our gospel, that you may gain the glory of our Lord Jesus Christ.
There is hope here. Paul doesn't emphasize that they will endure the Tribulation. He emphasizes that they are beloved, chosen from the beginning for deliverance, to gain the glory of our Lord Jesus Christ.
