God steps in....

Okay.  Here's letter (via Right Wing Watch) from a far right religious group that puzzles me.  If, in fact, their prayers to God stopped the Times Square bombing, does that mean he could have stopped 9/11 but didn't?  And what would that say about such a God that would allow such suffering?  (By the way, the prayer day described was a complete flop.  A few hundred people at the most showed up, when they were expecting close to 10,000.)
