We live in a time when marital fidelity is under assault. Driven by the forces of relativism, our society attacks sexual faithfulness on numerous fronts. The push for homosexual marriages, for example, comes at the end of the fall into perversion, not the beginning. Faithless husbands began the fall long ago, and our culture, with all its washed-out self-help books, fails to address the real problem -- sin. Addressed to men, Fidelity hits hard, using clear language and focusing on specific sins with specific solutions: adultery, divorce, polygamy, celibacy, pornography, and more. But in the end, the antidote to all sexual temptation is simple -- the godly honoring of the marriage bed: "Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge" (Heb. 13:4).
