Reasons for this vary. For some it’s all about heavenly trumpets: how many there are, and when they sound. For others, the teaching of the
apostle Paul that the godly “shall suffer persecution” and the words of the Lord himself that “in the world
you will have tribulation”
tip the scales in favor of a Church that will suffer through the end times along with the world. Others
compare the order of events in John’s Revelation visions with the future described
by the Lord Jesus in the gospels, leading them to anticipate martyrdom like so many of our fellow believers throughout
history. Still others believe the doctrine of the Rapture originated in the 16th century counter-reformation teaching of Papal Rome, and therefore consider it discredited.
All these are arguments from detail.
