Have you ever caught yourself being nervous in a dark room, in your own home? For example, every now and then, before I go upstairs for the evening, I will turn out all of the downstairs lights, and start walking up the stairs. And I will occasionally get this feeling that someone could be downstairs, behind me. I suppose I can't completely rule out the possibility that someone is hiding in my home, waiting for me to turn out the lights, etc., but it defies rational thinking.
It takes a few seconds to refocus, and laugh at myself. Since I know I take security of my home seriously enough, keeping doors locked, and using my alarm system, it would take a very serious effort to circumvent that security, and where I live, it is completely absurd to think that a person would take such steps - especially since I have nothing of any true value, like all of the homes in my neighborhood.
Anyway, I do understand that irrational thinking can grip humans at times. But this God of the universe stuff is so hard for me to understand. It is much more likely that Bigfoot will crash through my door, than some god smiting me for not thinking he is real.
