Third Temple Anyone?

So Jeff and I had a nice long conversation last nite about the idea of the Third Temple being built to reinstitute sacrifices, temple worship, etc. The Dispensationalists need this because in their viewpoint, this brings Antichrist into the picture, which by default would mean the Rapture prior to that. The question really is: Is it likely that it will happen? Will God allow it, knowing that it's the wrong way? Or did Jesus, Stephen in Acts 7, Paul in Galatians 3, or the author of Hebrews all say back then, "you've got it all wrong! All these things leading up to Jesus were but a shadow and a type of things to come."

I also don't need to explain that the prosperity gospel loves the Left Behind idea, because God doesn't want any of us to suffer. He wants us to have our BMWs and be whisked away, right?
