From creation, God instituted sex as a good gift, reserved for the union of a man and a woman within marriage (Genesis 1:27; 2:24). Jesus himself confirms this original design, reminding us that the two become "one flesh" (Matthew 19:5). Far from being shameful, sexual intimacy within marriage is celebrated throughout Scripture as a place of closeness, shared pleasure, and mutual faithfulness between husband and wife.
Because this gift is precious, the Bible calls us to honor its boundaries: sex outside marriage wounds both the body and one's relationship with God (1 Corinthians 6:18). The believer's body is the temple of the Holy Spirit, called to glorify God with it rather than misuse it (1 Corinthians 6:20). God wants his children sanctified, which means abstaining from sexual immorality (1 Thessalonians 4:3), and he calls everyone to honor marriage (Hebrews 13:4).
Many carry wounds connected to sexuality: sins committed, abuse suffered, desires at odds with God's Word. The gospel offers neither crushing condemnation nor easy indifference, but a real path of grace: in Christ, the repentant sinner is washed, sanctified, and declared righteous (1 Corinthians 6:11). Purity is therefore never a solitary performance, but the fruit of a living relationship with a God who forgives, restores, and gives strength to walk in holiness.

Frequently asked questions about sex
Is sex before marriage a sin according to the Bible?
The Bible reserves sexual intimacy for marriage and calls believers to flee any sexual relationship outside that context (1 Corinthians 6:18; 1 Thessalonians 4:3). This isn't because God despises the body, but because he wants to protect the intimacy and commitment that marriage alone can provide. For anyone who has already crossed that line, forgiveness and a fresh start are fully available in Christ.
What does the Bible say about masturbation?
The Bible doesn't address this topic explicitly; no specific rule is given. The biblical principle to keep in mind concerns the heart: whatever feeds lust or becomes an enslaving habit works against the purity God desires (Matthew 5:28). Everyone is invited to honestly examine before God whether their heart is free or enslaved.
What does the Bible say about homosexuality?
Yes, the Bible presents sexuality as a gift designed for the union of a man and a woman (Genesis 2:24; Matthew 19:4-5), which excludes homosexual practice. This isn't a judgment on anyone's worth or an excuse for contempt: every person is loved by God and called, like everyone else, to holiness and to the grace offered in Christ.
Is sexual pleasure allowed within marriage according to the Bible?
Absolutely: the Song of Songs beautifully celebrates desire and shared pleasure between husband and wife, and Paul encourages married couples not to deprive one another (1 Corinthians 7:3-5). Within marriage, sexual pleasure isn't merely tolerated - it's a good gift that God approves and blesses.
How can someone recover from sexual sin or pornography addiction?
The Bible never traps anyone in their failure: whoever confesses their sin finds forgiveness and cleansing in God (1 John 1:9). Healing often comes through confessing to a trusted person, the support of a church community, and a daily dependence on the Spirit to renew one's desires. God restores what sin has damaged, with no condemnation for those who come to him in Christ (Romans 8:1).
