These false teachers are springs without water, mists driven by the wind. The underworld has been reserved for them.
With empty, self-important speech, they use sinful cravings and unrestrained immorality to ensnare people who have only just escaped life with those who have wandered from the truth.
These false teachers promise freedom, but they themselves are slaves of immorality; whatever overpowers you, enslaves you.
If people escape the moral filth of this world through the knowledge of our Lord and savior Jesus Christ, then get tangled up in it again and are overcome by it, they are worse off than they were before.
It would be better for them never to have known the way of righteousness than, having come to know it, to turn back from the holy commandment entrusted to them.
They demonstrate the truth of the proverb: "A dog returns to its own vomit, and a washed sow wallows in the mud."
