excerpt from Os Guinness’ Fool’s Talk, Chapter Five—The Anatomy of Unbelief
There are four strands of unbelief — suppression, exploitation, inversion, and self-deception.
The common metaphors that view unbelief from one angle or another are — hardening, blindness, deafness, unnaturalness, rebellion, lies, deception, folly, and madness.
One way of summarizing the effect of the four features of unbelief is to focus on the inescapable tension and dynamic conflict inherent in unbelief. At the core of unbelief is ceaseless, unremitting and inescapable tension and conflict. Unbelief suppresses the truth in unrighteousness, but it is still always the truth, so it can never completely get away from it.
