Homosexuality is not the only sin mentioned in 1 Corinthians 6:9–10.
Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.
It’s not the only sin mentioned, but it is different from all the rest, at least right now. At this moment in history, contrary to the other sins listed here, homosexuality is celebrated by our larger society with pioneering excitement. It’s seen as a good thing, as the new hallmark of progress.
