this all knowing god, changes the rules about religion

Simultaneous belief in the irreconciliable tenets expressed in the Old and New Testaments cannot help but produce cognitive dissonance.

Cognitive dissonance can be briefly described as holding two contrary attitudes, beliefs, emotions or thoughts simultaneously. The effect of cognitive dissonance is increased tension.

"People who are involuntarily exposed to information that increases dissonance are likely to discount that information, either by ignoring it, misinterpreting it, or denying it."
