2 Peter 2:12-14, 20-22

These people are nothing but brute beasts, born in the wild, predators on the prowl. In the very act of bringing down others with their ignorant blasphemies, they themselves will be brought down, losers in the end. Their evil will boomerang on them. They’re so despicable and addicted to pleasure that they indulge in wild parties, carousing in broad daylight. They’re obsessed with adultery, compulsive in sin, seducing every vulnerable soul they come upon. Their specialty is greed, and they’re experts at it. Dead souls!

If they’ve escaped from the slum of sin by experiencing our Master and Savior, Jesus Christ, and then slid back into that same old life again, they’re worse than if they had never left. Better not to have started out on the straight road to God than to start out and then turn back, repudiating the experience and the holy command. They prove the point of the proverbs, “A dog goes back to its own vomit” and “A scrubbed-up pig heads for the mud.”
