Dear friends, I wanted very much to write to you concerning the salvation we share. Instead, I must write to urge you to fight for the faith delivered once and for all to God's holy people.
Godless people have slipped in among you. They turn the grace of our God into unrestrained immorality and deny our only master and Lord, Jesus Christ. Judgment was passed against them a long time ago.
I want to remind you of something you already know very well. The Lord, who once saved a people out of Egypt, later destroyed those who didn't maintain their faith.
I remind you too of the angels who didn't keep their position of authority but deserted their own home. The Lord has kept them in eternal chains in the underworld until the judgment of the great day.
In the same way, Sodom and Gomorrah and neighboring towns practiced immoral sexual relations and pursued other sexual urges. By undergoing the punishment of eternal fire, they serve as a warning.
Yet, even knowing this, these dreamers in the same way pollute themselves, reject authority, and slander the angels.
The archangel Michael, when he argued with the devil about Moses' body, did not dare charge him with slander. Instead, he said, "The Lord rebuke you!"
But these people slander whatever they don't understand. They are destroyed by what they know instinctively, as though they were irrational animals.
