Is it a sin to have sex with my lover?

God’s Design for Sex

The Lord created sex as an expression of love, intimacy, sharing, unity and procreation. Jesus said, “At the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.’ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate” (Matthew 19:4-6); The Lord also said, “Be fruitful, and multiply” (Genesis 1:22). So, Sex is God’s gift of love and procreation to a married couple.

“You Shall Not Commit Adultery”

The Bible tells us that sex outside the unity of marriage is sin. It is breaking the seventh commandment which states: “you shall not commit adultery” (Exodus 20:14). This prohibition for sex covers not only adultery (voluntary sexual intercourse between a married person and a partner other than the lawful spouse) but fornication (voluntary sexual intercourse between persons not married to each other) and impurity of every act, word, and thought (Matthew 5:27, 28).

This commandment is, our third duty toward our “neighbor.” We are to respect and honor the bond upon which the family is built, that of the marriage relationship, which should be to the Christian is as precious as life itself (Hebrews 13:4).

In 1 Corinthians 6:9-10 Paul says, “Do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men . . . will inherit the kingdom of God.“ And the apostle adds, “it is God’s will that you should be sanctified: that you should avoid sexual immorality” (1 Thessalonians 4:3).

Sexual Immorality

The scriptures give many other references that teach that sex outside of marriage is a sin:

“..abstain from…sexual immorality” (Acts 15:20).

Now the body is not for sexual immorality but for the Lord, and the Lord for the body” “Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body”(1 Corinthians 6:13,18).

Nor let us commit sexual immorality, as some of them did, and in one day twenty-three thousand fell” (1 Corinthians 10:8).

I shall mourn for many who have sinned before and have not repented of the uncleanness, fornication, and lewdness”  (2 Corinthians 12:21).

Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness” (Galatians 5:19).

But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints” (Ephesians 5:3).

Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry” (Colossians 3:5).

For this is the will of God, your sanctification: that you should abstain from sexual immorality” (1 Thessalonians 4:3).

As Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the Jude 7).


In marriage, a husband and his wife are one in a lawful, holy union (Genesis 2:24), but in fornication (sex outside marriage) a man and woman become one in an unlawful union. Only when it is according to God’s law can the union of the sexes be holy. God ordained that sex should be within marriage for the happiness and well being of the family. Abstinence before marriage saves lives, protects babies and gives sexual relations the proper meaning and value.
