What does the Bible say about sexual sin?

Scripture clearly delineates the sacredness of intimacy within the marriage covenant while condemning sexual sin outside of it. In Genesis, Joseph exemplifies integrity by resisting temptation, underscoring that sexual sin leads to unimaginable consequences such as destroyed homes and lives. Paul admonishes believers to flee fornication, emphasizing that sex outside of marriage is a great sin against God. This reflects God's design for marriage, which honors the union between a man and woman, highlighting the importance of chastity and fidelity as essential aspects of Christian life.
