How God destroyed three groups illustrates that he will destroy these ungodly people in your midst.

Jude 5-8

5 Although you previously knew all these things, there are certain things about which I desire to remind you. Do not forget that although the Lord rescued his people from Egypt, he later destroyed most of those same people, ones who did not believe in him. 6 And there were many angels to whom God assigned/gave positions of authority in heaven. But many did not continue to rule with authority in those positions. Instead, they abandoned the place that God gave them to live in heaven. So God has put those angels in chains forever in the darkness in hell. They will stay there until the great day when God will judge and punish them. 7 Similarly, the people who lived [MTY] in Sodom and Gomorrah cities and the nearby cities committed sexual immorality. They sought all kinds of sexual relations that differ from what God permits. So God destroyed their cities. What happened to those people and those angels shows that God will punish people, such as the ones who teach false doctrine, in the eternal fire of hell. 8 Similarly, these ungodly people in your midst also defile their own bodies by living immorally, because they claim/say that God revealed in visions that they should act that way. They refuse to allow anyone to have authority over them, and they ◄revile/speak evil about► God’s glorious/wonderful angels.
