Jude 1:7, 10

And don’t forget Sodom and Gomorrah and their neighboring towns, which were filled with immorality and every kind of sexual perversion. Those cities were destroyed by fire and serve as a warning of the eternal fire of God’s judgment.

But these people scoff at things they do not understand. Like unthinking animals, they do whatever their instincts tell them, and so they bring about their own destruction.
