St. Peter has in mind the parable of his Master (Matt. xii.; Luke xi.) which was spoken prophetically of the Jewish people. There Christ tells of the evil spirit which has been cast out, but no attempt made to fill his place with a better tenant. Soon finding no rest, he returns, and beholds his former home swept, and garnished, and unoccupied. Then he goes and takes seven other spirits more wicked than himself, who enter with him and dwell there. With what solemn meaning come those words which follow the parable, "Blessed are they that hear the word of God and keep it!" (Luke xi. 28). To have heard, and not to have kept, indeed makes the last state worse than the first.

For it were better for them not to have known the way of righteousness, than, after knowing it, to turn back from the holy commandment delivered unto them. These words of the Apostle point out the fear and care which should possess the hearts of those whom God blesses with large opportunities: fear lest they receive them amiss and fail to value them; care lest they pervert them to a wrong use. Our Lord's own words form the mightiest homily thereon when He spake to those cities of Galilee upon whom a great light was shining as He dwelt in their midst, but He could not do His mighty works there because of their unbelief. "He came unto His own, and His own received Him not." Hence the solemn denunciations of woe upon them: "It shall be more tolerable in the judgement for Tyre and Sidon, for Sodom and Gomorrah, than for them"; "The queen of the south shall rise up in the judgement against them and condemn." And more sorrowfully still He speaks to Jerusalem: "If thou hadst known in this thy day the things that belong unto thy peace, but now they are hid from thine eyes."

Christ went away unto the Father, but He left the Apostles their commission to teach the way of righteousness as He had taught it. "Teach them," He says, "to observe all things whatsoever I have told you; and lo, I am with you always." By the ministrations of St. Paul and his fellow-labourers the feet of these Asian converts had been set in the right way. They had made a profession of faith in Christ's sacrifice, and thus had been reckoned among the righteous, among those called to be saints. But the journey unto righteousness is made by daily steps in keeping God's law; and if these be not taken, the road may lie open, the traveller may see it, but he comes no nearer to the goal. Nay, in this road there is no standing still. They who fail to press forward inevitably slide back. It was here that these false teachers had failed. The command of God checked their evil appetites and greed; and so they set it at defiance and turned aside, and taught their deluded followers that God's freedom in its highest sense meant a licence to sin.

Here one of the Apostle's words is very significant. He says, not holy commandments, but holy commandment, telling us thus that the Divine law is all comprehended in the right ordering of the heart. In principle all God's laws are one. If that inward source of all our right and wrong be kept pure, from it are the issues of life; and every action flowing from it will then have a righteous aim. Thus men lead holy lives; thus they keep God's commandments in every relation. They do not in this life become free from offence; they stumble, because they are compassed by infirmity. But they act from a right motive; and this, and not the sum-total of results, is what the loving Father of men regards. Thus the Divine law is the law of true freedom, supplying a principle, but leaving the particular actions to develop according to the circumstances of each man's life. This is the freedom of which the Psalmist sings: "I will walk at liberty, for I seek Thy precepts" (Psalm cxix. 45); and one of our own poets extols a life so ordered by Divine law as the truest, grandest freedom:—

"Obedience is greater than freedom. What's free?

The vexed straw on the wind, the tossed foam on the sea;

The great ocean itself, as it rolls and it swells,

In the bonds of a boundless obedience dwells."

It has happened unto them according to the true proverb, The dog turning to his own vomit again, and the sow that had washed to wallowing in the mire. To describe in all its horror the abysmal depth to which these false teachers have sunk, the Apostle makes use of two proverbs, one of which he adapts from the Old Testament (Prov. xxvi. 11), while the other is one which would impress the Jewish mind with a feeling of utter abomination. The dogs of the East are the pariahs of the animal world, while everything pertaining to swine was detestable in the eyes of the Israelite. But all the loathing which attached to these outcasts of the brute creation did not suffice to portray the defilement of these teachers of lies and their apostate lives. It needed those other grosser features—the return to the disgorged meal; the greed for filth, where a temporary cleansing serves, as it were, to give a relish for fresh wallowing—these traits were needed ere the full vileness of those sinners could be expressed.

Solomon spake his proverb of the fool who goes back to his folly; but of how much grosser lapse is he guilty who, having known the mercy of Christ, having tasted the Father's grace, having been illumined by the Holy Spirit, turns again to the world and its pollutions, goes back into the far country, far away from God, and chooses again for his food the husks that the swine did eat!
