Belief in God = Organized Religion.
I did present an organized and a personal scenario.
However a bomb at the wrong place will end the idea of forever for the atheist but not for the deist.
Only if the deist was correct in the first instance to be a deist and if he has chosen the right deity and if that right deity is feeling generous on the day. Otherwise the atheist and the deist are both just roadkill. Of course 40 years into the future, a mere blowing up might just be a temporary set back whilst you upload your brain backup to a new substrate.
I don't doubt that on another thread we could have a good-going evolution-creation debate based on the Jefferson quote, suffice to say that both sides acknowledge a guiding hand - the devil is in the detail :-)
At face value Jefferson's quote could be viewed as an argument from personal incredulity - many things that astounded a man of his time are basic education to an 8 year old these days. The WTS haved based their Creationist views on such logic.
