So, ... just to be clear ..., do you believe then that there may be genetic 'seed' of Israel (Jews) alive unto the end, who may live in grievous sin all their life - and fall away to worship the beast, who will at the last moment be allowed to see the Truth of God Almighty and be taken to Heaven - despite all the wickedness they have done?
Ain't no pre-trib rapture, so you can forget asking me to agree to that false doctrine of the devil. And that is what you are trying to prod me about, with that fake "tribulation saints" idea from the Pre-trib Rapture theorists of men. This you can count on: by the time the "great tribulation" starts, each person will already be divided to one side or the other, and will remain in their belief to the day of Jesus' return. That means, if you believe the false Pre-trib Rapture theory from men when the trib starts, you will continue to believe it throughout that tribulation, all the way to the end of it, because at the end of it is actually when Lord Jesus showed His coming to gather His Church is (Matthew 24:29-31 and Mark 13:24-27).
God through His prophets foretold of the gathering of house of Judah and house of Israel back together again, in the lands He promise their fathers. And God through Jeremiah promised that Israel would never... end as a nation before Him. The 144,000 list of the sealed from the seed of Israel in Rev.7 is a testimony of their continued existence. So speculation that the 144,000 represent someone else other than who that Scripture says is just men's leaven.
If you don't know this, maybe more Bible study might be in order, as Lord Jesus did not cancel prophecies yet to come to pass that were written back in the Old Testament prophets.
2 Peter 3:1-2
3 This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance:
2 That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour:
