Paul is my only post trib teacher since he placed rapture after GT has ended.
Paul taught no such thing! Paul taught the gathering of the church first, then the Day of the Lord, the time of God's wrath.
By teaching that the church is present on the earth during the time of God's wrath, you do away with the fact that Jesus took upon himself God's wrath, satisfying it completely. Because of this, the wrath of God no long rests upon believers.
You people who believe that the Lord is going to put His church through the time of God's wrath, need to do a deep study on the seals, trumpets and bowl judgments. For those who endure patiently, Jesus said that He would keep out [out of] the hour of trial that is going to come upon the whole inhabited world. We are kept out of that time period, not through it or in it, but kept out of. If the church were to be gathered after the great tribulation, it would put the church through the entire wrath of God, right along with the wicked.
God does not punish the righteous with the wicked. And since the seals, trumpets and bowl judgments will affect the entire earth, then the church cannot be here during that time, because what is coming will be God's direct wrath, which believers are not appointed to suffer. Believers in Christ have been credited with the righteousness of Christ and reconciled to God.
You and others need to understand the purpose of the Day of the Lord and who it is against. Because it certainly isn't against the Lord's bride. You also need to understand that there is a difference between the trials and persecutions that Jesus said we would have as a result of our faith vs. God's coming wrath.
Regarding the rapture being placed after the great tribulation, if you are speaking about those who John sees come to life in Rev.20:4-6, those are the great tribulation saints who are introduced in Rev.7:9-17. This group is not the church, but are those who become believers after the church has been gathered and during the time of God's wrath. The resurrection has phases/stages to it:
* Christ the first fruits
* The church (then, when he comes, those who belong to him)
* The Male Child/144,000 (changed and caught up)
* The two witnesses
* The great tribulation saints
All of the above are apart of the first resurrection. Just fyi, 'first' does not mean 'only.' The first resurrection refers to all resurrections which take place prior to the resurrection which takes place at the end of the thousand years.
