In some cases some of these types have turned Revlation into a doom's day cult -repleat with revealed knowledge and date or event settings (which is prophesising) which never come to pass (thus false prophets).
We are not suppose to try and predict the date of Jesus's return, But Prophecy is something that is written through out the Bible and we do ourselves a dis-service and to GOD by not reading and looking at world events as foretold in the Holy Bible....GOD wants us to be aware of the sorrows that will be coming to earth this will make us stronger spiritually and keep us strong when we see so much pain and violence all around us...Prophecy IMHO is like a protective sheild around us...
I agree wholeheartedly. We treat the end-times like an investor uses the Wall Street Journal, speculating on world events like a stock broker trying to decide whether to sell short or long. Today's troubles and moral challenges are enough for us to be worried about. The Great Commission can't be fulfilled if we're hiding in bomb shelters.
And personally, I've never met a pre-tribber who didn't believe that Armageddon was coming within their (or at best the next) generation.
