Marriage failure stems from deep spiritual causes, primarily the breakdown of faithfulness to God's teaching on the permanency of marriage. Unfaithfulness, hypocrisy, and violence are key sins that profane the marriage covenant. Unfaithfulness manifests as treachery, where one spouse deceives or breaks vows, dishonoring the sacred agreement of marriage. Hypocrisy occurs when individuals commit sins against the marriage, yet seek God's blessing without true repentance or change of heart, profaning the covenant with insincere actions. Violence, not limited to physical abuse, includes any mistreatment—whether verbal, attitudinal, or through actions like adultery—that harms the spouse and destroys trust, staining the purity of the marriage bond. Hostility and hardness of heart further contribute to the defilement of marriages, often leading to irretrievable damage. God abhors divorce due to the destructiveness and pain it causes, viewing it as an act of violence in a relationship meant for tenderness and love. Despite allowing divorce in cases of serious defilement, God's original intent remains a lifelong union, reflecting His desire for permanence in the sacred bond of marriage.

Marriage failure in the United States has been a growing concern over the past several decades, marked by various societal shifts. The erosion of family values began with influences like the sexual freedom movement of the early 1960s, characterized by premarital cohabitation, adultery, and the spread of venereal diseases. The easing of divorce laws, allowing for no-fault divorces in many states, further contributed to marital breakdown. Feminism shifted dynamics by encouraging women to pursue equality outside the home, while abortion diminished the consequences of illicit sexual behavior. The emergence of AIDS in the early 1980s and the increasing visibility of homosexuality added to the challenges, alongside the proliferation of other sexually transmitted diseases. More recently, the concept of homosexual marriage has been introduced, which is seen as contradictory to the fundamental idea of marriage. Beyond societal factors, inherent difficulties in marriage arise from the complexities of uniting two distinct individuals. Communication problems often surface, such as a husband being too preoccupied with work to listen to his wife. Financial struggles, whether due to scarcity or abundance, create tension. Interference from in-laws can meddle in the relationship, and issues with children, such as favoritism or neglect, can cause division between spouses. Each partner brings unique sins and weaknesses that must be navigated, adding to the challenges of maintaining a successful marriage. Even in favorable times, marriage remains a difficult endeavor, with the odds often seeming stacked against those who are married or aspire to be.

Marriage failure is often rooted in a variety of societal and personal influences that undermine the sanctity and stability of the marital bond. Premarital cohabitation, widely practiced as a means to test compatibility, is associated with an increased risk of divorce, lower marriage quality, poorer communication, and higher incidences of domestic violence. This approach, driven by lust rather than patience or decency, often overwhelms moral considerations, leading to decisions that prioritize immediate desire over long-term commitment. The pervasive influence of mass media exacerbates these issues by using sexual allure to promote materialism and glorify fleeting pleasures, thus eroding the value of fidelity within marriage. This cultural emphasis on hedonism, where pleasure becomes the primary life goal, intertwines with sexual immorality, further degrading the marriage relationship by equating trivial choices with the profound decision of choosing a spouse. Additionally, a new moral code centered on self-fulfillment and situational ethics poses a significant threat to marital stability. This philosophy, which prioritizes personal circumstances over established norms, fosters a relativistic view where actions are justified if they seem harmless in the moment. However, such decisions often lead to unforeseen negative consequences, including guilt and broken families, as individuals lack the foresight to predict the true impact of their choices. The sexual instinct, distorted by cultural overstimulation, frequently operates against reason, clouding judgment in critical moments and leading to premarital sex or adultery. This emotional and physical drive often overrides rational decision-making, contributing to marital discord. Moreover, marriages based solely on physical attraction are inherently weak, likely resulting in indifference, divorce, or infidelity when the initial allure fades without deeper emotional or intellectual bonds to sustain the relationship. Inadequate understanding of marriage as a divine institution also contributes to its failure. Without a firm grasp of its sacred purpose and value, couples face serious challenges. Marriages lacking a union of body, soul, and spirit struggle to achieve the depth intended by God, often leading to joyless and unfulfilling relationships. Furthermore, marrying someone who does not share the same spiritual beliefs can result in a compartmentalized life, where the most meaningful aspects cannot be shared, leading to substantial unhappiness. Finally, the lack of mutual submission, love, and respect within marriage, as well as failure to fulfill roles with understanding and nobility, creates discord. When husbands and wives do not prioritize each other's needs or treat each other with consideration, the bond weakens. This is compounded when external pressures or personal failings, such as allowing children to dominate family decisions or letting love grow cold, are not addressed through submission to God's guidance, resulting in marriages that fall short of their potential for blessing and happiness.

Marriage failure, as a critical concern, stems from several fundamental causes that disrupt the unity and purpose intended for the relationship between husband and wife. The primary reason for failure in marriage is the self, with its various manifestations of selfishness. Selfishness, characterized by an inordinate self-love, prompts one to disregard the rights or feelings of others, leading to a deficiency in justice and goodwill toward one's spouse. This self-centeredness inevitably causes clashes and conflicts, as two autonomous selves oppose each other, creating discord at every level of the relationship. Another significant cause of marriage failure is the lack of thoughtful understanding. Many enter marriage driven by feelings and impulses rather than reasoned consideration, failing to think through the challenges and realities of daily life. Without a foundation of understanding, couples have no arguments or principles to fall back on when faced with difficulties, resulting in relationships that cannot withstand the stresses and strains of life. Additionally, a negative or worldly conception of marriage contributes to its failure. When marriage is viewed merely as a partnership or contractual arrangement, rather than a profound unity where two become one flesh, it lacks the positive, inspired perspective necessary for endurance. This perspective fails to reflect the ideal relationship of mutual submission and love, leading to a higher likelihood of breakdown. Neglect and abuse further exacerbate marital discord. Neglect, such as a husband spending excessive time away from his wife or failing to engage in meaningful interaction, breeds anxiety and destructive conditions. Abuse, whether physical or mental, inflicts damage not only on the spouse but also on the abuser, as it violates the fundamental unity of marriage where harming one is akin to harming oneself. Both neglect and abuse reflect a failure to nourish and cherish, essential components of a lasting bond. Lastly, taking a spouse for granted undermines the active, positive relationship required in marriage. When a husband views his wife merely as a housekeeper or stops considering her needs and pleasures, the relationship stagnates. Without continuous effort to think from a right perspective and to build up and protect each other, the marriage deteriorates under the weight of thoughtlessness and selfishness. These causes collectively highlight the necessity of mutual care, understanding, and a rejection of self-centeredness to prevent the failure of marriage.

Many marriages fail because young people marry outside the church, creating irreconcilable differences over teaching children, tithing, observing feasts, avoiding unclean foods, controlling drinking and smoking, and maintaining moral and sexual standards. Such unions often end in divorce or remain unhappy, as one partner lacks understanding of or commitment to God's way of life. Marrying outside one's race or ethnic roots produces similar strains, as differing cultures, holidays, and religious training divide the couple and leave children feeling unaccepted by one or both sides of the family. Failure also stems from inadequate dating practices that prevent proper evaluation of a prospective mate. Passive activities such as attending movies reveal little about personality, while going steady limits exposure to a variety of people and heightens the temptation to become physically involved before marriage. Without observing the other person when tired, hungry, stressed, or tempted, couples overlook signs of selfishness, disrespect, laziness, short-sighted goals, poor money management, or dishonesty. These character flaws surface later in conflicts over finances, fidelity, or child-rearing and destroy trust. Misuse of sex before marriage introduces guilt, shame, jealousy, and immature emotions that damage the relationship permanently. Couples who focus only on physical attractiveness rather than mental and emotional compatibility discover after a few years that gorgeous eyes or rippling muscles provide no foundation for resolving serious disagreements. Marrying without shared backgrounds, values, interests, energy levels, or views on children compounds these problems, since blending two dissimilar lives proves far more difficult than uniting similar ones. Finally, entering marriage without patience and faith in God during the present distress leads young people to rush into unions that prove unsustainable amid escalating division and persecution.

Marriage failure stems from unconversion, or hardness of heart, which produces violence against the marriage covenant by violating one or more of the three principles stated by Adam in Genesis 2:23-24. These principles require each partner to leave parents and form a new unit, to cleave unwaveringly to the spouse, and to bond sexually to the exclusion of all others. Such violence may take the form of sexual immorality under the broad Greek term porneia, which encompasses adultery, incest, pederasty, homosexuality, and other perversions, or it may appear in nonsexual expressions such as physical abuse, habitual lying that destroys trust, theft of love and care, drug addiction, refusal to work or support the family, constant anger, depression and whining that prevent communication, refusal of sexual relations, controlling behavior through fear, failure to separate from parents, or involvement with demons. In mixed marriages one converted partner and one unconverted, the unconverted spouse often refuses to adapt, creating stressful, warlike conditions without peace that undermine God's purpose. The converted partner may also contribute to the failure by failing to uphold responsibilities, yet God holds the converted person to a higher standard of accountability. Ezekiel 16 illustrates how spiritual harlotry, or idolatry in its many forms, likewise destroys the relationship. Although God hates divorce and intends permanence from the beginning, these failures render some marriages untenable, and He therefore permits divorce with the possibility of remarriage as an act of mercy so that His people may live in peace and pursue His Kingdom.

Marriage fails because Satan, the unseen author of moral decline, has mounted a sustained assault on the institution God created for human oneness and family stability. By first undermining faith in the sovereign Creator and the authority of His Word, the adversary persuades people that they are uncreated and therefore free to define right and wrong for themselves. This mindset elevates human opinion above divine command and opens the way for every subsequent attack. Humanists, operating from positions of influence in education, media, government, and entertainment, advance the deception that sex and love are equivalent and that moral standards are irrelevant. These claims contradict God's explicit limits: sexual intimacy belongs solely to one's legal spouse, and love is defined as keeping His commandments through sacrificial loyalty and outgoing concern. When sex is treated as the foundation of marriage rather than one expression of love, emotional frustration, adultery, and eventual separation follow. A second line of assault promotes rank immorality and hedonism throughout the culture. Churches often accommodate the shift by redefining sin as acceptable provided no one appears hurt, while statistics show fornication and adultery so widespread that out-of-wedlock births exceed those within marriage in some areas. The third prong simplifies divorce through no-fault laws and authorizes abortion on demand, removing both legal and moral restraints that once protected the marriage covenant. These measures echo earlier communist strategies that deliberately weakened Christian loyalty to spouse and God in order to advance state control. At root, every failure traces to the pattern first displayed by Adam and Eve. Their single act of disobedience instantly altered their hearts, damaged their relationship with God, distorted their regard for each other, and cost them the blessings of Eden. Sin never remains private; it produces shame, blame-shifting, and generational consequences that erode the oneness God intended. Thus marriage, designed to reflect the voluntary unity between Father and Son, collapses wherever carnal self-interest replaces sacrificial devotion to God's revealed will.

Sociologists identify the decline of marriage and the family as the root of many American cultural problems and trace this decline to five principal causes. The introduction of reliable pharmaceutical contraceptives removed the risk of unwanted pregnancy and thereby eliminated a strong practical incentive for couples to marry. The growing social acceptance of cohabitation further reduced marriage rates by presenting informal unions as a legitimate alternative, especially among the young. No-fault divorce laws converted marriage from a binding vow into a contract with an easy exit clause, which both cheapened the institution and encouraged its dissolution on a wide scale. The disappearance of civil remedies for alienation of affection eliminated another deterrent to infidelity, since an injured spouse could no longer seek monetary damages from a third party who had seduced his or her partner. Finally, the large-scale entry of women into the workforce conferred economic independence that lessened the financial necessity of marriage, facilitated divorce, and produced a strong inverse correlation between a woman's educational attainment and the number of children she bears. All five developments draw strength from the cultural emphasis on autonomy, understood as the freedom of individual choice. This emphasis, rooted in American individualism, consistently favors personal preference over the requirements of societal stability. Conservatives, who claim to defend traditional institutions, have offered little effective resistance to any of these trends, allowing the forces undermining marriage to advance largely unchallenged.

Adultery and related sexual sins cause marriage failure by violating the exclusive covenant between husband and wife that God established from creation, allowing sexual relations only within that bond. These acts break trust, as infidelity toward a spouse mirrors and fosters unfaithfulness toward God, often manifesting as idolatry that places other desires above Him. On a practical level, such breaches frequently produce divorce and shattered families, leaving children emotionally damaged and predisposed to repeat patterns of distrust and relational instability across generations. Pre-marital and extra-marital relations further erode marital foundations by introducing instability and hidden consequences that eventually surface, drawing in wider circles of people and institutions while weakening society as a whole through widespread faithlessness. The root cause lies deeper than physical acts, originating in the heart through lustful thoughts and a lack of self-control that defiles a person from within. Human nature resists the necessary heart transformation, making change a profound struggle, yet overcoming these impulses through divine power purifies motivations and prevents the transgressions that destroy marriages.

Sexual sins, particularly adultery, constitute a primary cause of marriage failure because they inflict wounds that can never be wholly healed or atoned for, leaving the betrayed spouse unable to be fully appeased. This principle is illustrated by the certainty that a person who takes fire into his bosom or walks on hot coals will be burned, just as one who seduces a neighbor's wife will be found guilty. Biblical accounts demonstrate the pattern: Reuben's act with his father's concubine cost him his birthright and branded him unstable; Israel's harlotry with Moabite women brought a plague that killed twenty-four thousand; and David's lust for Bathsheba resulted in the deaths of Uriah and their son, the disgrace of his house and God, the later defilement of his concubines, and the death of another son, Absalom. These failures arise from disobedience to the standard God established in Eden, where a man leaves his father and mother to become one flesh with his wife, intending the physical relationship to bind marriage in tenderness and love while producing children trained in His truth. Satan, unable to reproduce, targets the family through sexual perversions to destroy this plan, flooding society with pornography, unwed motherhood, sex-education programs that promote activity over abstinence, commonplace perversions, and divorce rooted in misconduct. The resulting broken homes and fatherless children stem directly from yielding to the lust of the flesh, the lust of the eyes, and the pride of life rather than fleeing immorality, removing every source of temptation from the mind, submitting to God, and resisting the devil through humility and cleansing of heart.

Marriage failure arises when individuals reject God's ordained covenant between one man and one woman, allowing society to unravel as morality and family structures collapse. Single men and women grow frustrated because the battle of the sexes, fueled by decades of feminist indoctrination and sexual revolution propaganda, has altered expectations. Women raised to compete with and surpass men often abandon modesty, high standards, and self-respect, approaching sex casually and signaling that they need neither husbands nor commitment, which leads men to view them as shallow and materialistic while many men themselves refuse to mature into trustworthy leaders. This dynamic intensifies when people marry without first becoming the right kind of person themselves, entering unions based solely on physical attraction or mismatched visions rather than shared emotional, intellectual, and spiritual compatibility. God established the pattern in Genesis by creating Eve from Adam as a helper comparable to him, making her for him, from him, and given to him, so that true union requires both partners to be Christians who submit to one another under Christ's headship. Marrying a non-Christian violates this order, producing only partial unions of body or mind while preventing the essential spirit-with-spirit bond and inviting years of heartbreak. Further causes include hedonism that treats sex as recreational pleasure outside marriage, sophisticated justifications for adultery that destroy trust, the ease of divorce that discourages working through difficulties, and abortion laws that exclude fathers from protecting their offspring and dissolve family cohesion. These attacks parallel ancient idolatry such as sacrificing children to Molech and stem ultimately from self-love and enmity against God. Without repentance, humility, and service modeled on Christ, marriages remain weak and headed for dissolution, confirming that failure originates in departing from the divine design that alone sustains lasting covenant relationships.
