In the context of human relationships, compatibility is a vital principle that God established from the beginning. God declared it is not good for man to be alone, and thus intended to create a helper comparable to him. This helper, as described, is one like himself, standing opposite to him, embodying both similarity and difference. The woman is made of the same essence as the man, sharing similar intelligence, skills, and potential, yet she is distinct in perspectives, emotions, strengths, weaknesses, aims, and needs. God designed her to be a complement and supplement to the man, compatible enough to ensure harmony, yet different enough to fill areas where he lacks, making them exponentially better together. This compatibility is reflected in the mutual need and interdependence between a man and a woman. A suitable companion brings unique strengths and talents to the relationship, addressing the other's deficiencies. The union of a man and his wife transforms a state of "not good" into a blessed and beneficial partnership, one that God desires and often orchestrates by bringing together those He deems fit for each other. Such a relationship, built on trust and loyalty, is of immense value, surpassing even precious stones, and is meant to endure for life. The concept of a helper does not imply inferiority but rather a role of supplying strength where it is needed. Just as God helps without being inferior, a wife supports her husband in areas of weakness, enhancing their unity. This mutual reliance fosters a partnership of equals, where both are essential to one another, working as a team with shared purpose. God's design for compatibility in marriage underscores the profound benefit of two becoming one, helping each other in their journey through life.

God desires compatibility and oneness among His people, emphasizing unity over division. He does not favor enforced multiculturalism or a tossed salad of differing beliefs, but rather a melting pot where unity prevails. This principle is crucial for rulers in the Kingdom of God, who must reflect oneness with God and with those they lead. A ruler must be like his followers to be effective, understanding their beliefs, laws, customs, traditions, and expectations. He must be familiar with their history, strengths, weaknesses, and hopes, being one of them to rule effectively. A foreigner ruling over a people would alter the familiar ways, potentially leading to a loss of identity for the nation. Mutual trust between ruler and people is essential, akin to a strong marriage where compatibility and shared values create the strongest bond. Christ exemplifies this rulership, striving for unity not only within the church but eventually with all humanity, unified with God. Therefore, the lesson is clear: a leader must be compatible with his followers, sharing their essence to govern with understanding and trust.

When considering marriage, compatibility in culture, character, religious beliefs, and outlook on life is essential. Disregarding these principles often leads to problems and hardships for the couple and their children. Making wise decisions about who to marry is crucial for one's future and the future of one's family. Behavior runs deep, shaped early in life, and is difficult to change, so if a characteristic is intolerable during courtship, it may remain a lifelong issue. People may stay in unhappy relationships due to a false sense of security, clinging to familiarity despite the relationship's flaws. Regarding interracial or intercultural marriage, while there is no prohibition based on race, differences in ethnicity, culture, and religion can pose challenges. Research indicates that marital breakup rates for interracial couples are slightly higher, and such unions are sometimes entered into for selfish reasons. Wisdom in choosing a partner who aligns with one's core values and beliefs is vital to building a strong, lasting marriage.
