Many people seem to believe that any expression of religious doubt reflects a moral weakness and poorly on the object of this belief. In simple terms, doubt is perceived to reflect badly on the Divine. The fact is, though, that doubt, actually, is solely descriptive of a person, reflecting his/her lack of certainty. And this lack of certainty is really just the natural consequence of being human. The Almighty is the only One Who knows the complete truth. We, all human beings, are just struggling to gain some perception of what is really going on. We ultimately, though, do not fully know. Doubt reminds us of this, of our humanity.
