Biblical Answer

The question of why God created sex only for marriage is a complex one, and it requires an understanding of God's design for human relationships and the purposes of sex. At the foundational level, we need to understand the basic principle of the Biblical sex ethic, which is why God confine sexual activity exclusively to married couples. According to the Bible, sex is a gift from God, created for human flourishing, and it is meant to be a source of joy and intimacy in marriage. However, sex outside of marriage is not only a violation of God's design but also a source of harm and damage to individuals and relationships.

The Bible teaches that God created sex to fulfill something basic in human nature, which is the desire for intimacy and connection with another person. Sex is meant to be a way of expressing love and commitment between two people who have pledged to spend their lives together. When sex is confined to marriage, it is a way of deepening intimacy and commitment, and it is a source of joy and happiness for the couple. However, when sex is taken outside of marriage, it can lead to harm and damage to individuals and relationships. This is why God prohibits sex outside of marriage, not because he is opposed to sex itself, but because he is concerned with the value of keeping sex unique to one special relationship.

The ultimate reason why God created sex only for marriage is because he is concerned with the value of keeping sex holy and pure. Sex is a sacred gift from God, and it is meant to be a source of joy and intimacy in marriage. When sex is taken outside of marriage, it can lead to a loss of what is best, and it can cause harm and damage to individuals and relationships. God's design for sex is not just about biology, but about relationships and intimacy. He created sex to be a way of deepening commitment and intimacy between two people, and he prohibits sex outside of marriage because he is concerned with the value of keeping sex holy and pure.
