On what are you basing your declaration that Eze 38-39 happens after the Rapture ..??
The only GOD-executed event after the rapture is Armageddon, and Exe is definitely not Armageddon. The final event is between GOD and Satan.
And .. God’s Word says that “It’s GOD’s desire that NONE should perish”. So, because of GOD’s love for humankind, why wouldn’t HE want to provide an event where more people could chose HIM, and be saved from eternal damnation ..???
Therefore, GOD would have no need to leave evidence of bones and weaponry for people to see .. if the rapture had already taken place.
Some will come to salvation during the Tribulation.
