Cheer, the Rapture isn't a critical doctrine but it is Biblical and that alone makes it important.
You just don't get it so your presumed timeline and perception of events is scrambled.
Truth is, the pretrib Rapture of the Church will be a sudden event, it will come with no warning. Understood correctly, the Rapture is comforting, not fearful (1 Thess 4:18).
The "strong delusion" passage you mention is and will be a warning for those who are left behind - AFTER the Church is "caught up". The Rapture will see no Christian left behind to go through the "Wrath of God" Tribulation, not even you.
You're not "close minded"? Well, I wonder if you've yet read a single one of the Bible passages I've posted? (I haven't read any of your supports because you've not given us any!)
"
He has already said" that believers - his children - are not subject to his wrath. I take that to certainly include the coming wrath of His seven years of Tribulation. (I'm sure you know it's there but you ignore 1 Thess 5:9 ... I don't!)
So, as usual in your stout disagreements, you cite no supporting scripture for your fuzzy position,
you just wave your hands in the air and tell the world about your specious "dreams". I believe you will need more than just telling people what you "think" to change many minds! ???
