Jude 1:4, 10-12

Some people have secretly entered your group. Long ago the prophets wrote about these people who will be judged guilty. They are against God and have changed the grace of our God into a reason for sexual sin. They also refuse to accept Jesus Christ, our only Master and Lord.

But these people speak against things they do not understand. And what they do know, by feeling, as dumb animals know things, are the very things that destroy them. It will be terrible for them. They have followed the way of Cain, and for money they have given themselves to doing the wrong that Balaam did. They have fought against God as Korah did, and like Korah, they surely will be destroyed. They are like dirty spots in your special Christian meals you share. They eat with you and have no fear, caring only for themselves. They are clouds without rain, which the wind blows around. They are autumn trees without fruit that are pulled out of the ground. So they are twice dead.
