There have always been people willing to confidently predict Jesus’ coming or the end of the world from time to time, and with the rise of the internet that stream of predictions appears to be almost continuous now. So what are we supposed to do with all these predictions? What does this Bible say about them?
Well, we should ignore any that say they know when Jesus will return, because scripture says that is impossible to predict. If it is a more localized prediction, write it down and hold them to that answer. If it is from God it will come true. If it is not, then we can safely ignore them from then on.
