What does the Bible say about sexuality in marriage?

The Scripture teaches that human sexuality is designed by God and is not inherently sinful, dirty, or gross. It is meant for the joy of married couples and serves as an illustration of the spiritual relationship between Christ and the Church. The Song of Solomon, while overtly sexual, uses this aspect of human experience to convey deeper spiritual truths. Furthermore, the text highlights that sexual relationships are confined to the context of marriage, emphasizing fidelity between one man and one woman as the rightful boundary of sexual engagement.
