Sexual Sins

Those who neither honor nor thank God refuse to recognize God’s attributes of eternal power and divine nature. They suppress these things with their living. They exchange God to worship images of people and creatures. Therefore, they are given to desires of sexual stimulation and using their bodies among themselves (Rom 1:18–28).

Should each person decide what is sexually right according to one’s own sexual desires or should society choose what is legal sexuality via common law? Society without an absolute standard is sexually fluid flowing in and out of abuses from one era to the next.

The Defining Standard

Many justify sexual sins and irrationally explain away the definition of sexual sins. People rationalize their lack of self-control and justify their personal situation rather than seeking answers to overcome such sins. However, this rationalizing keeps many from seeing how evil sin is and the state of the evil opposing them. By His nature, God is the moral standard, and God has given an objective moral standard in His creation. God gave sexual desires for marriage between one man and one woman to become one flesh (Gen 2:24; 1 Cor 7:1–9).

Christians need to have an awareness and strong conviction, so that believers abhor this evil (Rom 12:9). Without recognizing, thanking, and glorifying God, people will pervert natural desires into strange lusts (Rom 1:20–28). Humanity often corrupts morality, and so they need a moral corrective outside of themselves. The only selfless moral corrective is God and His Word. All other moral convictions come from a self and, or society.

Fornication and Adultery

When Jesus spoke of adulteries, fornications, and lewdness, He called these behaviors “evil things” that defile people (Mark 7:20–23). The definition of fornication is from the Greek word porneia. This behavior is any sexual intercourse outside of marriage between one man and one woman (1 Cor 6:16Eph 5:31Heb 13:4). Adultery is sex with another’s spouse or when the married has intercourse with anyone who is not one’s spouse. Jesus revealed that adultery includes divorcing and marrying another person unless the divorce was because one’s spouse committed fornication — extramarital sex (Matt 5:3219:9Mark 10:11–12Luke 16:18; cf. 1 Cor 7:10–11).

Jesus condemned all sexual sins. He did not need to specify that rape, incest, and homosexuality are sexual sins, because these behaviors are outside the natural union of marriage between a man and a woman (Mark 7:20–23). However, Jesus did infer condemnation of pedophilia when He opposed the abuse of children and alluded to sexual abuses against them (Matt 18:7–10Mark 9:42–50).

Jesus did not have to specify what He meant by fornication with a descriptive list. Jesus used the definition of fornication according to the Law of Moses when He spoke. Within the Law of Moses, immoral sexual behavior included all extramarital sex specifically adultery, premarital sex, incest, rape (pedophilia), sex during menstruation, homosexuality, bestiality, prostitution, and uncovering nakedness (Lev 1819:2920Deut 22:522–30). Jesus’s standard is stricter than the Law (Matt 5:28).

Lewdness and Lust

Christ spoke against sexual sins like lewdness. Some translation of the Bible use the world “sensuality” that is synonymous for lewdness. The apostle Peter defined lewdness as to “entice by sensual passions of the flesh” (2 Pet 2:18; cf. Luke 17:1Jas 1:13–14). To cause others to lust through tempting speech, revealing clothing, and nudity is lewdness. The Bible reveals that those who continue in lewdness will not inherit God’s kingdom (Gal 5:19–21; Eph 5:3–6).

On the other side, Jesus also taught not to look to lust (Matt 5:28). Looking at another person with lust is adultery in the heart. Jesus revealed, “But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart” (Matt 5:28 ESV). Lust is a heart problem that the sin of sexual impurity feeds. Jesus revealed that out of the heart proceed evil behaviors and evil thoughts such as adulteries, fornications, sexual covetousness, and sensuality (Mark 7:20–23).

Sexual Impurity

The Scriptures describe sexual impurity or “uncleanness” as a work of the flesh that keeps one from entering the kingdom of God (Gal 5:19–21; Eph 5:3–6; Col 3:5–7). The New Testament lists impurity or “uncleanness” as a distinct action among sexual sins. Holiness is the opposite of practicing sexual impurity and other sexual sins like fornication (1 Thess 4:7). The Scriptures set sexual impurity apart from fornication, adultery, lewdness, and lust (2 Cor 12:21; Eph 4:19). The practice of impurity involves the use of the members of one’s body (Rom 6:19). The Bible describes “impurity” to include sexual emissions (Lev 15:32; cf. Gen 38:6–10Lev 15:1618Deut 23:10). In the New Testament, this impurity is an intentional sexual sin.

People personally satisfy and fulfill lust by the sin of impurity with the members of one’s body (Rom 6:19). To this diligent student of Scripture, sexual impurity must be self-stimulation, masturbation. Self-stimulation is not a “natural outlet,” but an action that leads to more sins and stirs up lusts (Rom 6:19). The sin of sexual impurity comes from the heart and can occur by looking to lust (Matt 5:28; Rom 1:24). Sexual impurity is distinct from the heart. Those looking to lust struggle with this sexual impurity as lust and sexual impurity links with sexual sins of the heart. As the apostle Paul explained, God gives those who do not thank or honor Him over to the sexual impurity that leads to dishonoring bodies with others (Rom 1:24). These dishonorable passions can lead into the penalty of homosexuality (Rom 1:26–28).

Sexual impurity is opposed to self-control. The apostle Paul instructed Christians how to reject this sin of sexual uncleanness and become holy in Romans 6–8. Paul instructed giving one’s members to holiness for freedom from the slavery of sexual impurity to live in holiness (Rom 6:191 Thess 4:7). One must become holy and sexually pure by repenting of sexual impurity to overcome looking to lust for others and other sexual sins.

Conclusion

People will reject the definition of sexual sins when they reject the standard given by God in His holiness. However, the Christian must embrace holiness for salvation (Heb 12:14–16). The definition of the sexual sins is set according to the standard of marriage as the created institution for sexual union. God created man and woman in His image and for each other. God did not create humanity to go against their moral conscience. Sexuality is for marriage.
