From the time John the Baptist preached that the time was at hand (meaning very soon) to Peter saying "the end of all things is at hand" and Jesus promising his return in "this generation" of 2,000 years ago, things have continued as if they never had said those things.
It can't be emphasized enough that the whole New Testament is one big failed prophecy of the soon return of Jesus and the immediate arrival of judgment day. It didn't happen - get over it.
That some of the doomsayers, like Christadelphians, claim that God just felt sorry for us and is just giving us a little longer to repent because of an imagined 1st century apostasy means nothing but an excuse for continuing to be stupid. I mean, it has been 2,000 years, give-me-a-break!
Yes, it's very popular nowadays to claim that God has postponed judgment day indefinitely - just any old excuse to keep the cults up and running, I suppose.
