I most certainly am not a preterist, I'm a futurist, but if your bible is leading you to a pretrib understanding, perhaps you should change translations.
Oh I can debate the very best of your teachers.
Ask one of your teachers for a postrib rapture verse.
Tell em you will wait for a response.
Then wait and wait and wait.
They, like you will not be able to give any.
We own end time big time.
Matt. 24:29-31, 1 Thess. 5:3-5, Eph. 6:13, 2 Thess. 2:3-4, 1 Pet. 4:17-19, Rev. 6:9-11, Rev. 7:9-14 shows the post GT raptured/resurrected church arriving in heaven, Rev. 12:17, Rev. 13:7-10. These are all post-persecution verses. If by post-trib you mean post 70th week, then I agree there is no rapture at that time. Now I know you'll say these aren't the church, they are trib saints, but there is no such group. They are the still here church! That theology was made up by pre-tribbers to account for all the places it still shows who can only be described as church people.
You do not know the pretrib doctrine.
Of course those left behind martyrs , are the church.
They are tge 5 foolish virgins.
All 10 are virgins/saints.
5 worthy 5 foolish.
The rapture is worthy saints vs carnal saints.
Heaven authenticates via witnesses.
" let my word be confirmed in 2 or 3 witnesses."
1) Jesus said " pray That you may be counting worthy to escape the things about to come upon the Earth and stand before this son of god"
He said that to born again believers.
2) Jesus said " Because you have kept the word of my testimony. I will also keep you from the hour of testing that's about to come up on the whole world."
3) Jesus said "2 men will be in a bed. One will be taken the other 1 left. 2 women will be in a field, one will be taken in the other one left.
There are about 10 verses declaring the worthy of ones are taken in the rapture.
I could go deeper but you will trample the deeper things.
I am sure the virgin parable is risqué, as any allegory is trampled by you.
