What can we say? We have all been involved in and victims of this Christian bull-shit. I remember an elderly (jw) sister's telling me that in response to the nearness of the 1919 expectation that her mother sold their house.
And, if you were involved in serving Yahweh the "loving God" (haha) in his fulltime service, for any length of time, it may have cost you (as part of your life earnings) hundreds of thousands of dollars, if not a million or more.
And, we can think back to William Miller, whose teachings on the "end" became part of the American psyche, and informs American religious discourse to this day. His dates of 1843/44 all failed, with (according to one account) some adherents freezing to death (on one night) as they waited for the Lord to appear to them. Yahweh/Jesus had no mercy on them.
You can find a version of Miller's calculations in Wikipedia. Refer, en.wikipedia.org/wiki/William_Miller_(preacher) You will not fail to note their resemblance to Jws calculations.
And, early Christians also were to live in constant expectation, as is clear in the early Christian document, The Shepherd of Hermas.
(Reference: www.earlychristianwritings.com/shepherd.html )
That account was very popular in the early church, and accorded great respect within the church. A copy is bound into the Codex Sinaiticus. The beliefs of these early Christians as seen in this early writing are often quite unusual. But my point in referring to the work, is that the expectation of Christ's return among early Christians failed for them, just as it has failed Jehovah's witnesses on all the various dates and non-dates they have pointed to, and just as it failed those more orthodox Christians who expected the return and end in the year 2000.
Christ's return and the end of the world is just another failed Biblical prophecy, all those who hope in him are doomed to sad disappointment
