We are told in Scripture that it is possible for people, by repeated sins, to lose the capacity for embarrassment and shame. The Bible frequently speaks of the hardened heart, which causes a person no longer to feel remorse for his or her transgression. It is dangerous for us to rely totally on our guilt feelings to reveal to us the reality of our guilt itself because we can quench the pangs of conscience.
