What does the Bible teach about sex before marriage? Sex before marriage is clearly a sin, according to the Bible. Below are several Scripture passages that speak on the topic of sex before marriage.
2 But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.1 Corinthians 7:2
Here, we learn that a man should have a wife and a woman should have a husband to avoid sexual immorality. The implication is that a sexual act outside of the marriage relationship is considered sexually immoral.
These passages again uses the term, “sexual immorality,” which we have determined from 1 Corinthians 7:2 to refer to sexual thoughts and acts outside of the marriage relationship.
20 but should write to them to abstain from the things polluted by idols, and from sexual immorality, and from what has been strangled, and from blood.Acts 15:20
5 It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife.1 Corinthians 5:1
13 “Food is meant for the stomach and the stomach for food”—and God will destroy both one and the other. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body… 18 Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body.1 Corinthians 6:13, 18
8 We must not indulge in sexual immorality as some of them did, and twenty-three thousand fell in a single day.1 Corinthians 10:8
