Compatibility is the evidence of the oneness God designed for a husband and wife. Compatibility includes our: physical relationship, values, spiritual maturity, moral issues, how we spend our time and money, children issues, and every other area of life together. Your spiritual compatibility is foundational in defining the roles and responsibilities each have. In order to maintain compatibility, we must accept our spouse's strengths and weaknesses. The Bible gives us several instructions about how husbands and wives should relate to each other.
