The lesson reviews the biblical foundation of marriage as a covenant established by God in Genesis, emphasizing that a husband and wife become one flesh and that parents must release married children to form their own household. It then addresses divorce through passages in Deuteronomy, Matthew 19, Malachi, and 1 Corinthians 7, arguing that divorce is serious, painful, and never to be treated casually, but also that there is no “one size fits all” rule, especially in cases involving abuse, abandonment, or other weightier violations of marriage. The teacher stresses that while God hates the damage caused by divorce, God can forgive repentant people, and the church should not treat divorced believers as second-class Christians.
