Dude, there is no rapture or tribulation chosen just for plot device! We are constantly under assail for our faith. We see the hungry and the thirsty and scurry past them, telling ourselves that once my business is done, I'll go back to them. . . . but we forget to remember on purpose.
We are not puppets and God is not the puppet master. We have free will to choose the left hand or the right hand path. We do have a bless3ed map to keep us on track, and that is the Church and all she encompasses, from Holy Scripture to comfortable sacraments, to Our Lord's Own Examples.
How the world ends or was created is about as germane as whether the chicken or egg was here first! We are here. We do have a pathway. We do have the Holy Spirit. It is like arguing about the chosen word for English translation for "serpent" in the Garden of Eden story: was it a snake or a snake that had legs and then lost them as some allege? Would that be a lizard then? Would that be evolution, by chance, a most interesting amount of sand to throw into the gears' lubrication that concept!
Why was the world united about the basics of the end times and salvation and the sacraments until the 1500s? Then it got interesting, but by the late 1800s it just got and stays just plain weird with snake handlers, revival tents, jets for tv preachers and their wigs, novel innovations such as "prosperity preaching" and the ever exciting "rapture and tribulation for fun and profit."
There is no point arguing with the insane and seriously brain damaged unless it is for fun and the edification of those who are alongside for the joyride.
