\v 3 Beloved, while I was making every effort to write to you about our common salvation, I had to write to you to exhort you to struggle earnestly for the faith that was entrusted once for all to God's holy people.
\v 4 For certain men have slipped in secretly among you. These are men who were marked out for condemnation. They are ungodly men who have changed the grace of our God into sensuality, and who deny our only Master and Lord, Jesus Christ.
\v 5 Now I wish to remind you—although once you fully knew it—that the Lord saved a people out of the land of Egypt, but that afterward he destroyed those who did not believe.
\v 6 Also, angels who did not keep to their own position of authority, but who left their proper dwelling place—God has kept them in everlasting chains, in utter darkness, for the judgment on the great day.
\v 7 So also Sodom and Gomorrah and the cities around them gave themselves over to sexual immorality and perverse sexual acts. They serve as an example of those who suffer the punishment of eternal fire.
\v 9 But even Michael the archangel, when he was arguing with the devil and disputing with him about the body of Moses, did not dare to condemn him for slander, but he said, "May the Lord rebuke you!"
\v 10 But these people insult whatever they do not understand; and what they do understand naturally, like unreasoning animals, these are the very things that destroy them.
\v 12 These people are dangerous reefs at your love feasts, feasting with you fearlessly—shepherds who only feed themselves. They are clouds without rain carried along by winds; autumn trees, without fruit—twice dead, uprooted.
\v 15 He is coming to execute judgment on everyone. He is coming to convict all the ungodly of all the works they have done in an ungodly way, and of all the bitter words that ungodly sinners have spoken against him."
