I am at work on a phone so ill give a quick answer, based on my memory. I remember it taught in church like 10 years ago and it stuck. God promised redemption to jews as his chosen people, that has not happened as they are still looking for his coming. The church will be raptured and with it goes the holy spirit from among the gentiles. The two witnesses will be preaching from jerusalem and they will realize the blood of Christ on their hands and repent, while in second thessalonians’s it tells that those that reject Christ now, inferred as not having his promises which is gentiles, will be turned over to the great delusion and fall under the antichrist. God has his chosen people that he promised to bless snd the tribulation will be that redemption for them.
Yes, I am familiar with that general type of teaching, I just was hoping someone could point out to me where exactly they found the basis of that teaching in the Bible, since I have never been able to locate it.
