The Book of Revelations contains a curse upon those who would alter it's contents. This "curse", naturally, had no effect--and the original vision (and writing) of the Apostle John may never be found. What remains of his writing has been grossly distorted and promoted in various forms as predictions of imminent doomsday. The dates of the end have come and gone many times and will continue to come and go as long as there are those that long for an end to things. I'm sure the motives are varied. Some long for perceived "justice"--personal spiritual reward, and punishment for their perceived enemies. BUT the end is not coming anytime soon. Jesus promised to return and I'm confident that He will do so one day. But as He told us plainly while He was in the flesh, the time is not for us to know. I will make a guess. I observe that mankind has made some progress in the past 2000 years, but I would suggest that this progress is insufficient. This is important because I think it very unlikely that He would return to say the same message. I predict the time will be ripe when Jesus' revelation of a loving Father in heaven and brotherhood of man is widely embraced throughout the world. At that time, mankind will be ready and receptive to new revelations. Such a time seems likely hundreds of years away--and certainly, there is no guarantee that Jesus would choose to come even then. All that we can do now is speculate. But pining for the "rapture" serves no good purpose. It's difficult to see any good or meaningful teaching that comes from rapture doctrines.
