Just read Revelations. Basically, there will be a huge influx of impostors and false idols that all are very cunning and charismatic. As soon as one of them declares him self God, that's the beginning of the end. Eventually, after so many years of the Anti-Christ's reign Jesus reincarnate arrives to prove him wrong and the believers are swept away to heaven, leaving in their spirit bodies. So really, when you see Jesus in the coffee shop you should be wary. Unless of course you believe Revelations has already begun. EDIT: This was a very harsh summary. Somewhere along the line, there is Armageddon which is a pretty important part. I'm sure there was something else I forgot to mention.
