Introduction Sex education for children and adolescents is often obtained from parenting seminars held by schools. But sex education for husband and wife that is right according to the Bible is challenging to find. Even if there are, they are usually in the form of seminars, and to attend them; a fee is not cheap. The Church should answer this need by providing sex education for married couples in discipleship classes, seminars, or retreats explicitly held for married couples (Halawa, 2020). In addition, teachers from the Church have more value than general teachers because they must have understood the truth of God's word. There is objective evidence of exemplary in the harmony of their families. Proper sexual relations, according to the Bible for married couples, significantly affect family harmony. Often divorce cases occur because of problems in the sexual relationship of married couples. One of the causes of conflict that often occurs is due to poor communication. To get a quality sex relationship, it's necessary to have good communication between husband and wife. So harmony in the family is closely related to the quality of sexual relations between husband and wife (Avianti and Hendrati, 2011). This research paper was written to answer the needs of married couples in the Church. How can they have proper sex according to the Bible? Have there been irregularities in having sex? Do both parties have sex out of love? How can they have good communication, especially when it comes to sex? How can they have a harmonious family? Abstract Currently, many family problems occur due to poor communication. If this is allowed to drag on, it can lead to divorce in the family. And if examined more deeply, married couples who want to divorce have serious problems in sexual relations between husband and wife. This research paper provides a solution for married couples to have good sex relations and have good communication to create a harmonious family. And the most appropriate solution is to provide sex education for married couples. Sex education provided must be accurate according to the Bible, described in detail, according to the needs of married couples, and answer all existing problems. The Church can facilitate sex education for married couples by opening discipleship classes. The Church as the body of Christ must solve married couples who are having problems becoming married couples who are harmonious in God.
