Unquestionably, there is nothing more important than having a solid factual and rational basis for one's faith. To the many who think of faith as a belief strongly held and without evidence to support it (and often even in spite of much evidence to the contrary), that may seem an outrageous statement. Logically, however, if believing something strongly doesn't make it so, as human experience daily proves, then it is the greatest folly to continue on with a "faith" which, because it has no basis in fact but merely in fancy, must inevitably prove to be empty. The cost could be eternal and irrecoverable.
