The Unwashed Heart and the Vain Purposes Cherished in it
Jeremiah 4:14
O Jerusalem, wash your heart from wickedness, that you may be saved. How long shall your vain thoughts lodge within you?


There are here an exhortation and a question which, taken together, pierce very deep, and suggest once more the true cause of all the terrible calamities which are to befall Israel; for though Jerusalem is addressed, the repentance and remedy for all the evils in question must come from the action of a united people. Jeremiah's words in ver. 10 are in a measure representative words; they indicate the way in which the nation would conclude that Jehovah had promised one thing; whereas unite another thing had happened, and that evidently by his disposition. And so Jehovah meets Jeremiah with this word, so that he shall not persist in a mistaken attempt to harmonize Jehovah's predictions. Further, he is to declare the same thing to Jerusalem, that being the great center where kings and princes, priests and prophets are gathered together. Instead of looking outward and ignorantly complaining of God, let them look inward, with practical intent, and see what they can do by way of heart-reformation. These stupendous perils can all be removed, but Jehovah by himself cannot remove them. In one sense, of course, he could do so. The wind might be made to subside, the lion be driven back to his thicket, the destroyer of the Gentiles annihilated. But there would be no permanent putting right in this if Israel remained the same. Israel indeed might think that, if only the enemies vanished, then the sword would indeed be withdrawn from the soul. The hearts of the king and princes did not perish simply because of the hosts that were gathered against them. This was a reason so far; but in another sense no reason at all, seeing it did not go to the root of the matter. But now Jehovah does go to the root of the matter; his Word is indeed a sword reaching deeper than the superficial thoughts of the people.

I. THE EXHORTATION.

1. The heart is to be cleansed. The heart. Persistently does God drag these people to look within. Either they were not willing to do so; or not able to do so, or, what is perhaps a more correct way of putting it, they lacked both willingness and ability. They would look anywhere but to the true cause of all their ills and to the true sphere where redemption and security were to be worked out. If they would only attend to their hearts and see in their hearts what God saw in them, all the seeds of peril, corruption, and everlasting shame, then they would get on to the right way, and being delivered from fundamental errors in their thoughts, they would come to the apprehension and practice of fundamental truths. They had already been told of the mockery of a mere outward circumcision, and enjoined to circumcise their hearts. Now the figure is varied, and they are told to cleanse their hearts. It is because the heart of the king and the prince is so polluted that it perishes. If it were a clean heart it would be a strong heart, invincible against panic and despair.

2. The filth that is to be taken out of the heart is wickedness. It takes a long time to work the conviction into the minds of many people that wickedness is as filth. These very people loathe the waifs and strays who think nothing of being constantly begrimed with dirt. To such the impurity of the great unwashed is a loathsome thing; it nauseates them to come within sight or scent of it. But let such recollect that even if, as far as their bodies are concerned, they have daily changes of fine linen, white and clean, that is a mere trifle if the consciousness within be habitually defiled by inhuman and degrading thoughts. There is, of course, a very practical truth in the common saying that "Cleanliness is next to godliness;" but cleanliness of the conscience, removal of every slimy stain of self, is but one of the aspects, of perfect godliness. If only we are laboring to cleanse our hearts from wickedness, all other cleanliness will assuredly follow. In proportion as wickedness is cleansed out, there will follow all outward decencies, courtesy of manner and refinement of tastes. The right inwardly grows to the comely outwardly; but if that inward right be lacked, then all apparent comeliness is but the whited sepulcher.

3. The mode of cleansing. The word chosen to indicate this is a very significant one. The mere general term for cleansing is not sufficient; nor even the more restricted but still general term for cleansing with water. The washing to be done is that sort which in the literal instance is to be done by a vigorous trampling of the feet. The Hebrew word is the same one in which the profoundly penitent David prays that God would wash him from his iniquity, and again to wash him so that he should be whiter than snow (Psalm 51.). And so here we have another instance of the unremitting thoroughness which marks this chapter. It is the heart that is to be cleansed, and that by the most vigorous kind of washing. The accumulated filth of years has entered into the very texture of the fabric. The truth is that the only way of carrying out the exhortation is to submit the heart to him in exactly the same spirit as David did. God is the Cleanser, and only when our nature has passed through all his purifying agencies shall we really know what perfect human nature is. We do indeed see that perfection in Jesus, but with such distorted vision that the seeing cannot be called seeing as we ought to see.

II. THE QUESTION. The thoughts with respect to which the question is asked are really purposes. This will come out more clearly on considering some of the expressions in which the same Hebrew word is used; e.g. when the woman of Tekcah spoke to David of God devising means to bring back his banished (2 Samuel 14:14); so Eliphaz tells Job that God disappoints the devices of the crafty (Job 5:12). Several of the Proverbs contain the word. The thoughts, i.e. counsels, of the righteous are just (Proverbs 12:5). Where there is no deliberation, purposes are disappointed (Proverbs 15:22). There are many devices in a man's heart, but the counsel of God shall stand (Proverbs 19:21). Purposes are established by counsel, i.e. there must be wisdom in forming them, and prudence in carrying them out. A comparison of these selected passages will amply suffice to show what God means by vain thoughts, and what sort of practical thoughts he would wish us to put in their place. Man is meant to live wish definite ends in view, on which he may expend his strength and faculties. But when these ends are his own - self-originated and self-gratifying - then they are emphatically vain. They can only continue by deceiving the mind that proposes them and holds to them. The question therefore is as to when our eyes shall be opened to perceive the right purposes of life, the solid and attainable ones, the purposes that are not vain, because they are God's purposes and because he provides all resources needed for carrying them out. Jerusalem wished these terrible troubles from outside to be at an end, just that it might resume its own projects. On the other hand, God wished it from the very heart to adopt his projects in order that then he might take all obstacles and enemies completely out of the way. - Y.
