What does the Bible say about immorality?

Bible Topic · WEB

The Bible teaches that sexual immorality is sin flowing from the fallen human heart, and calls God’s people to flee it and pursue holiness through Christ. Jesus shows that lust itself is morally serious, while Mark 7:20-23 locates such evil in the heart. Hebrews 13:4 honors marriage and warns of God’s judgment, and 1 Corinthians 6:18 urges believers to flee sexual sin because their bodies belong to the Lord. God’s will is sanctification, expressed in self-control and honorable conduct (1 Thessalonians 4:3-5). Yet believers facing temptation may trust God’s faithful provision of a way to endure (1 Corinthians 10:13), repent, and live by the Spirit.
