If the devil lied every time, then the gig would be up b/c he'd be predictable and nobody likes a liar. So there has to be enough truth so as to at least give a seeming likelihood of truth overall. So he won't f you every time, and on those few occasions that he does, its every true Christian's duty to forgive him, and love him. LOL, it had to be the devil who taught people to love their enemies. The Christians don't think so, and this is one basis of the cognitive dissonance that makes them neurotic.
