The Bible teaches that sex is reserved for marriage between one man and one woman. It doesn’t use the exact phrase “premarital sex,” but condemns it as sexual immorality (Greek: porneia, including fornication).

• 1 Corinthians 7:2 — “But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.”
(Marriage is the God-given solution to avoid immorality.)

• Hebrews 13:4 — “Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.”
(The marriage bed is pure; all other sexual activity is immoral.)

• 1 Thessalonians 4:3-5 — “For this is the will of God, your sanctification: that you abstain from sexual immorality; that each one of you know how to control his own body in holiness and honor…”

• 1 Corinthians 6:18 — “Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body.” The Bible views sex as a beautiful gift for the lifelong covenant of marriage (Genesis 2:24; Matthew 19:4-6). Anything outside that—including before marriage—is sinful, but forgiveness is available through Christ (1 Corinthians 6:9-11).
