Scripture does not lie about human nature. It does not soften the wickedness of Nabal, rehabilitate Judas, or offer a sympathetic backstory for Jezebel. It names what happened, names what it was, and lets the weight of it sit. That unflinching honesty is not cruelty toward those figures — it is honesty in service of our healing. Mirrors of Iniquity moves through fourteen biblical lives and fourteen distinct sins — not vague moral categories, but specific, diagnosable conditions of the soul. Cain's envy. Balaam's mercenary gift. Eli's passive complicity. Haman's genocidal pride. Jehoiakim's methodical contempt for the Word of God. Each sin is anatomized with precision, because a misdiagnosis could cause death, and most people are misdiagnosing themselves. Against the monastic tradition of the seven deadly sins, this work returns to the three Bible categories of sin — avon, peshach, hattat — and to an understanding of sin that penetrates intention, thought, and the hidden architecture of the will. Among the world's religions, only the biblical framework traces sin to a cosmic origin, diagnoses it to the level of thought (Matthew 5:28), and provides a singular external remedy. But this is not a book of despair. It is a gallery of mirrors on the way to a door. Every chapter ends where Scripture always ends: not with the sinner, but with the Savior. For every soul honest enough to look.
