Thank God for His grace, whether He transforms me before the GT or whether He takes me up after, His grace will be sufficient for me. If He takes me before I will be with Him for eternity, if not I know He will in a few years. I'm not sure where I stand, I was a strict pre-trib. Here's where no one seems to have an answer. The story of Noah and Lot, they were both taken out of the judgement on the wicked, with Noah he was in the Ark the day the flood came, yet he was also preserved through that judgement. Lot the fire and brimstone did not rain down until he left the city, then the judgement came, he was rescued from the judgement he was totally taken out. In Luke 17 Jesus put both of them in His teaching on the coming kingdom.
I think calling it a false doctrine or of the devil is dangerous because if it is true where does that put you. Paul said prophecy is in part, but when the perfect cones we will fully know or as Daniel put it in 9:24 all prophecy will be fulfilled. So no one fully knows what is going to happen. Sure we can say, but the prophecies of His first coming were all true, of course they were but, we are looking at them after they were fulfilled. After Jesus explained the destruction if the Temple, the sign of His coming and the end of the age to the disciples and what did they think about those things? In Acts 1:6 “Lord, will you at this time restore the kingdom to Israel?”
So after the Lord Himself explained it all to them, somehow it seems that they thought that His resurrection was His return and He was going to judge the world, I did say it seems. Whatever they believed they had in their minds that His resurrection somehow lead to the restoration of the kingdom of Israel. There were more then like people that viewed the suffering servant prophecies as it being a picture of Israel's sufferings (an assumption) and that why the Messiah would come in triumph. So don't be so sure about your eschatology, here's something to think about. God has always delivered the just from judgement on the wicked.
Here's what Peter says II Peter 2:4-9 "For if God did not spare angels when they sinned, but cast them into hell and committed them to chains of gloomy darkness to be kept until the judgment;5 if he did not spare the ancient world, but preserved Noah, a herald of righteousness, with seven others, when he brought a flood upon the world of the ungodly;6 if by turning the cities of Sodom and Gomorrah to ashes he condemned them to extinction, making them an example of what is going to happen to the ungodly;7 and if he rescued righteous Lot, greatly distressed by the sensual conduct of the wicked8 (for as that righteous man lived among them day after day, he was tormenting his righteous soul over their lawless deeds that he saw and heard); 9 then the Lord knows how to rescue the godly from trials, and to keep the unrighteous under punishment until the day of judgment,10 and especially those who indulge in the lust of defiling passion and despise authority."
Which one is it, preserve or rescue, doe He preserve us through the GT or does He rescue us from the GT?
