2 Peter 2:20-22

Verse 20. For if after they have escaped the pollutions of the world. This does not necessarily mean that they had been true Christians, and had fallen from grace. Men may outwardly reform, and escape from the open corruptions which prevail around them, or which they had themselves practised, and still have no true grace at heart.

Through the knowledge of the Lord and Saviour Jesus Christ. Neither does this imply that they were true Christians, or that they had ever had any saving knowledge of the Redeemer. There is a knowledge of the doctrines and duties of religion which may lead sinners to abandon their outward vices, which has no connexion with saving grace. They may profess religion, and may know enough of religion to understand that it requires them to abandon their vicious habits, and still never be true Christians.

They are again entangled therein and overcome. The word rendered entangled, (εμπλεκω,) from which is derived our word implicate, means to braid in, to interweave; then to involve in, to entangle. It means here that they become implicated in those vices like an animal that is entangled in a net.

The latter end is worse with them than the beginning. This is usually the case. Apostates become worse than they were before their professed conversion. Reformed drunkards, if they go back to their "cups" again, become more abandoned than ever. Thus it is with those who have been addicted to any habits of vice, and who profess to become religious, and then fall away. The reasons of this may be,

(1.) that they are willing now to show to others that they are no longer under the restraints by which they had professedly bound themselves;

(2.) that God gives them up to indulgence with fewer restraints than formerly; and

(3.) their old companions in sin may be at special pains to court their society, and to lead them into temptation, in order to obtain a triumph over virtue and religion.

(b) "again entangled" Lk 11:26, Heb 6:4, 10:26
Verse 21. For it had been better for them, etc. Compare Mt 26:24. It would have been better for them, for

(1.) then they would not have dishonoured the cause of: religion as they have now done;

(2.) they would not have sunk so deep in profligacy as they now have; and

(3.) they would not have incurred so aggravated a condemnation in the world of woe. If men are resolved on being wicked, they had better never pretend to be good. If they are to be cast off at last, it had better not be as apostates from the cause of virtue and religion.

(c) "better" Mt 11:23,24, Lk 12:47,48 (d) "way of righteousness" Prov 12:28
Verse 22. But it is happened unto them according to the true proverb. The meaning of the proverbs here quoted is, that they have returned to their former vile manner of life. Under all the appearances of reformation, still their evil nature remained, as really as that of the dog or the swine, and that nature finally prevailed. There was no thorough internal change, any more than there is in the swine when it is washed, or in the dog, This passage, therefore, would seem to demonstrate that there never had been any real change of heart, and of course there had been no falling away from true religion. It should not, therefore, be quoted to prove that true Christians may fall from grace and perish. The dog and the swine had never been anything else than the dog and the swine, and these persons had never been anything else than sinners.

The dog is turned to his own vomit again. That is, to eat it up. The passage would seem to imply, that whatever pains should be taken to change the habits of the dog, he would return to them again. The quotation here is from Prov 26:11: "As a dog returneth to his vomit, so a fool returneth to his folly." A similar proverb is found in the Rabbinical writers. Of the truth of the disgusting fact here affirmed of the dog, there can be no doubt. Phaedrus (Fab. 27) states a fact still more offensive respecting its habits. In the view of the Orientals, the dog was reckoned among the most vile and disgusting of all animals. Comp. De 23:18, 1Sam 17:43, 2Sam 3:8, 9:8, 16:9, Mt 7:6, Php 3:2. See also Horace, II. Epis. l, 26:--- vixisset canis irnmundus, vel arnica luto sus.

On the use of this proverb, see Wetstein, in loc.

And the sow that was washed, etc. This proverb is not found in the Old Testament, but it was common in the Rabbinical writings, and is found in the Greek classics. See Wetstein, in loc. Its meaning is plain, and of the truth of what ;s affirmed no one can have any doubt. No matter how clean the swine is made by washing, thin would not prevent it, in the slightest degree, from rolling in filth again. It will act out its real nature. So it is with the sinner. No external reformation will certainly prevent his returning to his former habits; and when he does return, we can only say that he is acting according to his real nature--a nature which has never been changed, any more than the nature of the dog or the swine. On the characteristics of the persons referred to in this chapter, (2Pet 2:9-19,) see the Introduction, & 3.

This passage is often quoted to prove "the possibility of falling from grace, and from a very high degree of it too." But it is one of the last passages in the Bible that should be adduced to prove that doctrine. The true point of this passage is to show that the persons referred to never were changed; that whatever external reformation might have occurred, their nature remained the same; and that when they apostatized from their outward profession, they merely acted out their nature, and showed that in fact there had been no real change. This passage will prove--what there are abundant facts to confirm--that persons may reform externally, and then return again to their former corrupt habits; it can never be made to prove that one true Christian will fall away and perish. It will also prove that we should rely on no mere external reformation, no outward cleansing, as certain evidence of piety. Thousands who have been externally reformed have ultimately shown that they had no religion, and there is nothing in mere outward reformation that can fit us for heaven. God looks upon the heart; and it is only the religion that has its seat there, that can secure our final salvation.
