Once Saved Always Saved vs. II Peter 2:20-22

II Peter 2:20-22 reads For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.The people in this passage had become Christians, as they had escaped the pollutions (footnote says “sins”) of the world through the knowledge of Christ. Only a Christian has escaped sin through Christ. Notice also that in verse 22's analogy of the pig, the pig had been washed from the mud. That means the person being depicted in the analogy had been washed from his sins.That person had now become entangled again in sin, had gone back into living the ways of the world. The passage says the result is that such a person is worse off than if had never known Christ (become a Christian) to begin with. Worse than lost couldn’t mean saved, could it?II Peter 2:20-22 then is another clear passage that teaches that a Christian can fall from grace.
