We live in a sex-saturated society. It smiles at monogamous marriages, encourages abortion as a means of birth control, promotes and endorses kinky sex as a means of entertainment, claims that moral absolutes don’t exist, and really believes that people can violate moral standards and escape the consequences. Fulton J. Sheen was right when he said, “The Victorians pretended sex did not exist; the moderns pretend that nothing else exists.’’
Authority (vv. 1–5). There are several reasons why the Lord gives clear instructions concerning personal sexual hygiene, sexual morality, and marriage. For one thing, we’re created in the image of God, and the Creator knows what’s best for His creation. God certainly wants married couples to enjoy the beautiful gift of sex, but He also wants them to avoid the terrible consequences that come when His laws are violated.
God had chosen Israel to be the channel through which His Son would come into the world, and it was important that the channel be sanctified. The breakdown of marriage in the Jewish society and the adopting of pagan practices could threaten the plan of God for their redemption. This seems to be the emphasis of Malachi 2:15. The Lord was “seeking godly offspring’’ (niv) that can come only from godly marriages.
A Christian marriage should be a witness to the world of the love Christ has for His church (Eph. 5:25–33), but if that marriage isn’t pure and faithful, the witness is destroyed. If husbands and wives can’t love each other as Christ loves the church, why invite their unsaved friends to be saved and share in Christ’s love?
Three times in this passage God said, “I am the Lord’’ (Lev. 18:2, 4–5). The phrase is used forty-two times in Leviticus 18—26. That’s all the authority we need for the standards that we hold! The Lord warned Israel not to look back and imitate the sins they saw in Egypt, nor to look around and imitate the sins of the Gentile nations (18:3). When the Jews entered Canaan, they would discover that the people there were unspeakably immoral; Israel would have to maintain a position of separation in order to be pleasing to the Lord. The church today must maintain that same position (2 Cor. 6:14–7:1; Eph. 5:1–14; Col. 3:1–7).
Obedience to God’s commandments brings life (Lev. 18:5). Indeed, other biblical writers often quoted this verse (see Neh. 9:29; Luke 10:28; Rom. 10:5; Gal. 3:12). If people could perfectly obey God’s law, their obedience would save them, but, of course, nobody can. Therefore, salvation is wholly by faith, totally apart from the works of the law (Rom. 3:19–31). However, after we’re saved, our obedience to the will of God, as revealed in the Word of God, is the basis for fellowshipping with God and enjoying the abundant life He wants us to have.
Standards (vv. 6–23). Since God invented sex and ordained marriage, He has every right to establish the regulations that control them, and our obedience will help protect these wonderful blessings from the defilements of the world. The laissez faire attitude of the humanistic world that says “anything goes’’ is not for the Christian. When it comes to moral standards, we’re becoming more and more of a persecuted remnant, but we dare not retreat.
The repeated phrase “uncover the nakedness’’ simply means “to have sexual relations with.’’ These laws would apply not only to marriage but also to casual contacts that were immoral. The prohibitions are listed in this chapter; the penalties are spelled out in chapter 20.
Leviticus 18:7–18 deal with incestuous relationships. These regulations are based on the fact that, in marriage, the man and woman are one flesh (Gen. 2:21–25; 1 Cor. 6:16; Eph. 5:31). A person who had relations with his stepmother, for example, would be “uncovering the nakedness’’ of his father; for the father and stepmother would be one (Lev. 18:8; see 1 Cor. 5:1ff.). Most modern societies prohibit consanguineous marriages, not because of what the Bible says but because of the consequences of such unions. There is a tendency for their children to inherit the recessive detrimental genes and bring out the worst in the family tree rather than the best.
Leviticus 18: did not prohibit what is known as “levirate marriage.’’ (“Levir’’ is the Latin word for “husband’s brother.’’) This occurred when a deceased husband’s brother married the widow so as to beget sons who would continue the family name and protect the family inheritance (see Deut. 25:5–10). The law stated in Leviticus 18: prohibited only illicit relations between brother-in-law and sister-in-law.
The seventh commandment, “You shall not commit adultery’’ (Ex. 20: nkjv), is expressly stated in Leviticus 18: (see Deut. 5:18). A man might argue, “I can enjoy my neighbor’s wife because she isn’t a relative, so it’s legal.’’ But God said it was wrong, and that settled it. The Bible repeats the stern warnings against adultery (see Prov. 2:16–19; 7:5–22; Matt. 5:28; Rom. 13:9; Gal. 5:19; James 2:11).
The warning about Molech (Lev. 18:21) will be dealt with when we study 20:1–5.
This section climaxes with prohibitions against homosexuality (18:22) and bestiality (v. 23; see Ex. 22:19; Deut. 27:21), with the warning that these sins are defiling, detestable (niv), and a perversion (niv). The best commentary is Romans 1:24–32 (see also Gen. 18:16—19:38; Judg. 19; Deut. 23:17–18, where a male cult prostitute is called a “dog’’).
That people who have committed any of these sins can be forgiven and become God’s children is clear from Matthew 12: and 1 Corinthians 6:9–11; that God expects them to repent and forsake their old lifestyle is clear from 2 Corinthians 5:21; Ephesians 5:1–10; and Colossians 3:1–7.
Consequences (vv. 24–30). The picture here isn’t a pretty one. Sexual perversions are like disease germs; they make a society and a nation sick. Then the land itself becomes sick and must vomit out its filthy people the way a human body vomits out poison. How tragic that people made in God’s image should end up as vomit! Please note that these were Gentile nations that were judged—peoples with whom God had not made any covenants, but He still held them accountable for their filthy deeds against nature (Rom. 1:18ff.).
If God so dealt with Gentile nations, to whom He’d never given His law, how much more will He hold accountable those who claim to know Him and possess His Word? There are dire consequences to sexual sins, and the judgment is greatest where the light has been the brightest. Alas, the nation of Israel disobeyed God, defiled their land, and were vomited out into captivity. Today, there are both secular and religious organizations that openly espouse an immoral lifestyle contrary to God’s Word; in God’s eyes, they’re making society sick.
