Dr. S. I. McMillen illustrates in a chapter entitled “The High Cost of Getting Even,” from his book, None of These Diseases, how physical maladies including ulcers, high blood pressure, and strokes are connected to harboring resentment and hatred toward others. He says, “It might be written on many thousands of death certificates that the victim died of ‘grudgitis.'” Dr. McMillen describes how hating a person enslaves the one who hates:
The moment I start hating a man I become his slave. I cannot enjoy my work anymore because he even controls my thoughts. My resentments produce too many stress hormones in my body; I become fatigued after only a few hours of work. The man I hate may be miles from my bedroom, but more cruel than any slave driver he whips my thoughts into such a frenzy that my inner-spring mattress becomes a rack of torture. I really must acknowledge that I am a slave to
every man on whom I pour out my wrath.
See: Rom 12:19-21; Eph 4:31
