They think that they can force God’s hand. They’re that arrogant.

Anyway, the whole fundie end-times narrative is late 19th-century fanfic. It not only contradicts their scriptures, it’s also incoherent and badly written. At least Dante, when he made things up, was consistent with the core beliefs, as well as his work being far better-written and more coherent than the source literature. But the Rapture is just the rantings of tent-show shysters. Even bronze-age shepherds did better.
