There is hope and forgiveness for every sexually immoral person. Paul mentions in verse 11, after describing sexual sins, “And that is what some of you were.” But they were cleansed and forgiven. There is no confessed and forsaken sin beyond God's redeeming grace.

What does God say about immorality?

1 Corinthians 6:9–10 -
