There are many verses in the Bible relating to sex. Unfortunately because of our sin nature most of these verses deal with sexual immorality or impurity. God designed sex as a gift for married couples to enjoy within their marriage. The Bible clearly states that sex outside of marriage is sin.
“The book Song of Songs gives a detailed description of the love two people shared. It describes not only their emotional love, but also their sexual attraction. This book of the Bible is a description of pure romantic love as the Lord intended it.”
God’s plan for sex is clearly defined in Genesis. Genesis 2:24 says that a man will leave his parents to be united with his wife. This verse says that “they will become one flesh.” One flesh refers to the uniting of two monogamous people through sex. This verse makes it clear that the Lord wants us to wait to have sex until we are married. In Genesis 1:26-31 the Lord tells Adam and Eve to be fruitful and multiply. His intention was for them to enjoy their sexual relationship as they populated the earth. The book Song of Songs gives a detailed description of the love two people shared. It describes not only their emotional love, but also their sexual attraction. This book of the Bible is a description of pure romantic love as the Lord intended it.
If sex was designed for marriage, and marriage only, we can conclude that any sexual acts that occur outside of marriage are sinful. This would include having sex before marriage or having an adulterous relationship while married. The Bible refers to this as sexual immorality. Galatians 5:19-21, Ephesians 5:3, and Colossians 3:5-7 warn against sexual immorality. These verses describe sexual impurity as sinful and displeasing to God. The Bible states that sexual immorality and impurity are obvious acts of the sinful nature (Gal. 5:19).
“All other sins a man commits are outside of his body, but he who sins sexually sins against his own body.”
I Corinthians 6:12-20 also warns against sexual immorality. This passage implores its readers to flee from sexual sin. I Corinthians 6:18 says that “All other sins a man commits are outside of his body, but he who sins sexually sins against his own body.” This is a strong warning because it makes a distinction between sexual sin and all other sin. I Thessalonians 4:3-5 says that God’s will is for us to learn to control our own bodies in order to avoid sexual sin. According to these verses learning to control our own bodies is holy and honorable.
The Bible is clear when it comes to sex. Hebrews 13:4 says that the marriage bed should be kept pure, and that marriage should be honored by all. God created the gift of sex for married couples to enjoy within their marriage. The Bible gives clear warning against violating God’s plan for sex. There is no more precious gift than to be able to present yourself as a virgin to your spouse on your wedding day and to commit yourself to that person, and that person only, for the rest of your life.
