In Rev. 2 the first church is Ephesus, the church whose eyes are not on Jesus; they focus on other things. The second message is to Smyrna, the faithful poor church. The third message is to Pergamum, the church of idol worship and pagans hiding sensual sins. The fourth message is to Thyatira, the church that tolerates paganism. The fifth is to Sardis, the dead works church. The sixth is to Philadelphia, the small but committed church. And finally, the seventh message is to Laodicea, the rich, materialistic lukewarm church.
Then, the church is no longer mentioned. Tie that in with the verses you pointed out, and you have a pre-trib. rapture. Yet, the word "rapture" is not recorded in the Bible.
After the church is no longer mentioned, there is a sound of a trumpet and John finds himself in heaven standing before the throne of Almighty God. Then the seven seals are opened in the Book, one seal at a time.
I believe that we will be "raptured" before the tribulation.
If Jesus comes before the tribulation, or any suffering at all on our part, we're all flying together - even the mid/post tribbers. :) In the meantime, it seems more reverent and scriptural to live as though we expect to die for Christ, than to expect Him to rescue us from any pain or discomfort.
After which, we will then rule over assigned parts of the world with Christ during the Millenium kingdom.
