Isn't one time enough?

Every few years a fringe Christian leader
or group predicts when Jesus Christ is coming back to earth. The latest date,
announced on billboards in some mid-sized American cities, is May 21 of this
year.
It does not seem to matter to these
groups that dates have been set before in church history, and that the dates
come and go and Jesus doesn't make his appearance. Apparently hope--and
hype--springs eternal in the hearts of those with millennial aspirations.
The second coming was a fairly dominant
theme in the congregation I grew up in. It was a fearful prospect: would I be
ready when he came? If he takes all his followers with him, would I be left
behind? Would I get caught in some act that displeases Jesus?
