The what if your wrong argument.

[Oldandeasilyconfused]

What if they're wrong?

The question is arse about. Why on earth should I believe they might be right?

(1) There is no credible evidence to prove the premise of their argument. IE the existence of god.

(2) The doctrine of the rapture was an imaginative invention of a couple of American puritans in the seventeenth century. The frootloopery of the rapture remains in the purview of the lunar religious right, a tiny minority of Christians world wide.

In some modern traditions of Christian eschatology, the Rapture is a reference to "being caught up" referred to in 1 Thess 4:17, when, in the End Times, the Christians of the world will be gathered together in the air to meet Jesus Christ.[1] Rapture is used in at least two senses, in the sense of pre-tribulation views in which a group of people will be "left behind" and as a synonym for the Resurrection generally.[2][3][4][5]

The concept of the Rapture, in connection with premillennialism, was expressed by the 17th-century American Puritan father and son Increase and Cotton Mather. They held to the idea that believers would be caught up in the air, followed by judgments on the Earth, and then the millennium.[12][13] The term Rapture was used by Philip Doddridge[14] and John Gill[15] in their New Testament commentaries, with the idea that believers would be caught up prior to judgment on the Earth and Jesus' Second Coming.
