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.
