The Jesus Christian teaching is that before Jesus returns (Yeah, we believe that Jesus will return!) there will be a time of intense persecution against all believers. We don't set any dates. "Soon" is just soon, and in general, it seems that prophecies take LONGER than we expect to actually come to pass.
We also believe that AFTER Jesus returns, his followers will rule the world for a thousand years (the "Millenium").
But please not that I have referred to "all believers" and "his followers" here. Jesus Christians teach that being a member of our community does not guarantee that one is a believer/follower, and being out of our community does not mean that a person is NOT a believer/follower. This is just one of many beliefs that do NOT fit the classic profile of a cult, but which gets glossed over in an attempt to paint the picture blacker than it is.
Blacker? Using that word in that context is racist. Out here in the system, we object to using terms that have racist connotations.
