A chief purpose of marriage and family is to teach proper, godly government, providing an environment to learn submission to authority and how to oversee others in love. In the ideal marriage relationship, the husband has authority over his wife and family, similar to Christ's authority over His Bride, the church. Love, as outgoing concern for everyone, forms the basis of this government, with Jesus Christ governing His church through sacrificing, sanctifying, cleansing, glorifying, nourishing, and cherishing it. These actions guide the husband, the head, on how to foster a happy, successful marriage. The husband's authority is balanced by loving care, while the wife's submission is ultimately met with glorification, producing enduring, harmonious mates, happy children, and righteous character. Authority in marriage, though often disrespected, must be wielded justly and fairly, balanced with kindness and concern. A couple should establish their own household, as remaining under parental roofs confuses roles and responsibilities intended for the husband-wife relationship. A definite break from life as a child to life as an adult spouse is necessary, allowing the man to be the head of his own household and the wife to have undivided loyalty to her husband. For the marriage to work best, a couple should set up their own home as soon as practicable, enabling the man to be king of his castle and his wife, his queen, without interference from parents or in-laws. Parents may offer advice or help, but the couple should be on their own to grow and develop the character needed now and for God's Kingdom. A couple should delay marriage until the husband can support his wife financially and emotionally, ensuring they are mature enough to establish a separate household.

In the United States, marriage has faced numerous challenges over recent decades, contributing to its instability. The inherent difficulties of uniting two distinct individuals, each with unique sins and weaknesses, create potential obstacles that must be overcome. Communication problems often arise because men and women do not communicate in the same way, and they typically approach life differently—men tending to act first and think later, while women often let emotions lead. Diverse backgrounds, in-law issues, and childrearing challenges further complicate marital harmony, making many marriages prone to collapse. Marriage is not an easy proposition, yet it remains a vital part of most people's lives. Although God has not commanded everyone to marry, the majority are likely to take this route. After baptism, the decision to marry is the most significant one a person can make, requiring deep consideration both before and during the commitment. The marriage vow marks the beginning of a process of refinement and growth, binding husband and wife more closely while enhancing the development of holy, righteous, godly character. God created both men and women in His own image, establishing their equal potential before Him to be transformed into His image and inherit His Kingdom. Though equal in potential, they differ in mental, physical, and emotional makeup, with unique inclinations, skills, and abilities. Marriage, as a union of equals under God's authority, carries a spiritual and imperative quality, reflecting the God-plane nature of human relationships and the shared goal of becoming like God.

The biblical concept of husband and wife being one flesh is a profound principle originating in Genesis 2:24, where a man leaves his father and mother to be joined to his wife, becoming one flesh. Jesus Christ reinforces this in Matthew 19:6 and Mark 10:8, emphasizing that they are no longer two but one flesh, highlighting a deep unity beyond mere illustration. This one flesh principle, also mentioned in Ephesians 5:31 and I Corinthians 6:16, signifies a binding union, akin to being glued together, as the Greek word kolláo and the Hebrew word dabaq suggest, whether in marriage or illicit relations. God does not view the sexual union of man and wife as cheap; as Hebrews 13:4 states, marriage is honorable, and the bed undefiled, while fornicators and adulterers face judgment. Each intimate act further binds the spouses, making marriage precious. Beyond the physical, the focus of one flesh is on closeness and togetherness, as expanded in I Corinthians 6:18-20 and 7:2-4, where spouses are not their own but belong to each other, lacking authority over their own bodies. This unity means living, thinking, planning, and working as one, striving for absolute togetherness as the ideal. God expects married couples to work toward being so committed and in love that they function as a perfectly oiled unit. Marriage serves as a training ground to learn how to be one spirit with Him, preparing to be the Bride of Jesus Christ. Couples must pull in the same direction, like a yoke of oxen, straining for the same ultimate glory. God frowns upon a 50/50 marriage, desiring each spouse to give everything to the other, owning each other fully. As the Shulamite in Song of Songs 6:3 realizes, the ideal marriage is one where each partner is wholly committed, stating, "I am my beloved's, and my beloved is mine," striving to live according to God's will with true love and outgoing concern for the other.

Marriage is presented as a divine institution established by God at creation, in which a man and a woman become one flesh through a covenant bond that encompasses companionship, romantic love, sexual union, joint livelihood, parenting, and a shared relationship with the Father and Jesus Christ. God Himself joins husband and wife, pronouncing the union in Eden and ordaining it as the foundational human relationship that precedes family and society. This joining carries permanent weight, as the two are no longer separate but one flesh, and what God has joined man must not separate. The relationship serves a larger divine purpose: it functions as a type and training ground for the eternal marriage between Jesus Christ and His church. Faithfulness within human marriage prepares believers for the never-ending covenant with Christ, while unfaithfulness, especially through divorce and remarriage, contradicts the sanctity and permanence God requires. God hates divorce because it violates the covenant and leads to further sin, though allowances exist in cases of sexual immorality or violence. Throughout Scripture the husband-wife bond mirrors God's relationship with Israel and Christ's relationship with the church, with the husband called to love, nourish, and cherish his wife as Christ loves the church, and the wife called to submit to and respect her husband as the church submits to Christ. Practical principles for sustaining this relationship include choosing to commit for better or worse, speaking or refraining from speech with gentleness, making the house a home through shared care, marrying the whole family with patient forbearance, living in selfless love that never fails, and remaining together until death. These choices cultivate the unity, peace, and service that reflect the coming divine marriage. By maintaining such faithfulness now, couples learn the sacredness of covenant love that will characterize their eternal union with Christ.

In the beginning God formed man and woman as complementary parts of one flesh, naked and unashamed, their physical differences intended to foster unity rather than division within His very good creation. After they ate from the tree of the knowledge of good and evil, their eyes were opened to those differences in a new way, prompting them to cover themselves with fig leaves in the first act of selfish division. God then declared the resulting curse upon the woman: her desire would be toward her husband and he would rule over her. This pronouncement describes an ongoing power struggle in which each seeks dominance, a self-inflicted consequence of relying on human wisdom instead of revealed truth. The same relational fracture extends beyond marriage into all human interactions, yet it appears most sharply in the husband-wife bond. Only where true Christianity flourishes does the curse begin to ease, as husbands and wives are instructed to emulate the relationship between Christ and the church. Wives are to submit rather than contend, and husbands are to love rather than dominate, each practicing the self-sacrifice that restores the original unity. This pattern is reinforced by the command to walk worthy of the calling through lowliness, longsuffering, and the bond of peace, nourishing and cherishing one another as one flesh so that the marriage reflects the banner of truth under which all division is overcome.

The significance of comfort, or the lack thereof, profoundly impacts human relationships, particularly in the context of husband-wife dynamics. Experiences with comfort during childhood create lasting imprints that shape how individuals connect and love in adulthood. A lack of affection in early years can lead to self-reliance and emotional closure, making it challenging to bond deeply with a spouse and potentially stifling marital intimacy. Conversely, growing up in an environment filled with anxiety, due to overprotection or criticism, may result in a tendency to appease and avoid conflict, which can foster resentment over time and hinder honest communication in marriage. Additionally, unpredictable parental affection can instill fears of abandonment, causing individuals to idealize relationships and react with anger or rejection when expectations are unmet, thus straining spousal connections. In environments of chaos or abuse, responses may vary between becoming controlling and aggressive or submissive and tolerant of mistreatment, both of which can obstruct the development of a healthy, balanced partnership in marriage. These imprinted styles can hinder the ability to truly cleave to a spouse, affecting the depth and stability of the relationship. However, regardless of past experiences, there is hope for healing and growth. As individuals are comforted by the God of All Comfort, they can become conduits of that same comfort to their spouse. Through drawing closer to God, fears and anxieties can be conquered, allowing for vulnerability and trust in marriage. God's constant nature provides security, teaching forbearance and the ability to maintain connection even when expectations are not met. By experiencing God's love and comfort, individuals learn to relate to their spouse in healthier ways, fostering stronger, more supportive marital bonds.
