You've been reading a little to much Tim Lahaye.
Tim Lahaye, don't know him... is he an author or a theological scolar or what ?
Update: I looked at his website and he's pretrib, and i'm most definately not a pretrib believer
I observe Jewish new year for the last 10 years or so, partly because I believe the rapture will take place on that day sometime in the near future (so it's out of respect [not imminent expectation])
Also because I believe God himself works through this calender; so stuff thats prophecied for 'this or next year' is actually already starting and taking shape from the previous or next Rosh celebration.
