"A new study suggests that prayer can indeed guide people away from adulterous behavior." The Economist explains that it is God who most effectively reproaches infidelity: "Infidelity is rampant in nature. Birds, mammals, amphibians and even fish all cheat if the conditions are right, forcing mates to remain perpetually vigilant. People are no different. Although cheats are publicly condemned, or in some cases impeached, infidelity is common and public disapproval does little to dissuade the sinner. The disapproval of God, however, is a different matter."
