Sexual sin in the Bible encompasses a range of immoral behaviors that deviate from the divine standards set for human sexuality. The biblical text often refers to sexual sin using terms such as "fornication," "adultery," and "uncleanness." For instance, in 1 Corinthians 6:18, Paul instructs believers to "flee from sexual immorality," indicating that such actions are not only sinful but also detrimental to one's body and spirit. The Bible presents sexual relations as sacred and designed within the context of marriage (Hebrews 13:4), where it is celebrated as a gift from God. The Old Testament laws, particularly in Leviticus 18, outline various sexual sins, including incest, bestiality, and adultery, emphasizing the need for holiness among God's people. Sexual sin is often portrayed as a rebellion against God's created order and can lead to severe consequences, both spiritually and socially. In the New Testament, Jesus reinforces the sanctity of marriage (Matthew 19:4-6) and warns against lustful thoughts, equating them with the act of adultery itself (Matthew 5:28). Overall, sexual sin in the Bible is viewed as a serious transgression that impacts one's relationship with God and the community.
