While there's no profit in running anyone down, I do wonder sometimes why TV preachers spend so much MONEY (it costs a lot of money to be on TV) preaching almost nothing but the End Times stuff.  Jesus said to watch -- that means to prepare your heart for God and focus on your relationship with Him; it doesn't not mean expending a bunch of time, effort and money in predicting exactly when He's coming back.  I fail to see the benefit in all this End Times rhetoric -- if you know you're ready, then get over it and move on to something else (preferrably spreading the Gospel to the lost).  IMHO
