"Return ye, I pray you, each from his evil way, And make good your ways and your doings!"
If the prophetic warning fulfil its purpose, and the nation repent, then as in the case of Nineveh, which repented at the preaching of Jonah, the sentence of destruction is revoked, and the doomed nation is granted a new lease of life. The same truth holds good reversely. God's promises are as conditional as His threats. If a nation lapse from original righteousness, the sure consequence is the withdrawal of Divine favour, and all of blessing and permanence that it confers. It is evident that the prophet directly contradicts the popular persuasion, which was also the current teaching of his professional opponents, that Iahvah's promises to Israel are absolute, that is, irrespective of moral considerations. Jeremiah is revealing, in terms suited to the intelligence of his time, the true law of the Divine dealings with Israel and with man. And what he has here written, it is important to bear in mind, when we are studying other passages of his writings and those of his predecessors, which foreshow judgments and mercies to individual peoples. However absolute the language of prediction, the qualification here supplied must usually be understood; so that it is not too much to say that this remarkable utterance is one of the keys to the comprehension of Hebrew prophecy.
But now, allowing for antique phraseology, and for the immense difference between ancient and modern modes of thought and expression; allowing also for the new light shed upon the problems of life and history by the teaching of Him who has supplemented all that was incomplete in the doctrine of the prophets and the revelation granted to the men of the elder dispensation; must we pronounce this oracle of Jeremiah's substantially true or the contrary? Is the view thus formulated an obsolete opinion, excusable in days when scientific thinking was unknown; useful indeed for the furtherance of the immediate aims of its authors, but now to be rejected wholly as a profound mistake, which modern enlightenment has at once exposed and rendered superfluous to an intelligent faith in the God of the prophets?
Here and everywhere else, Jeremiah's language is in form highly anthropomorphic. If it was to arrest the attention of the multitude, it could not well have been otherwise. He seems to say that God changes His intentions, according as a nation changes its behaviour. Something must be allowed for style, in a writer whose very prose is more than half poetry, and whose utterances are so often lyrical in form as well as matter. The Israelite thinkers, however, were also well aware that the Eternal is superior to change; as is clear from that striking word of Samuel: "The Glory of Israel lieth not nor repenteth; for He is not man, that He should repent" (1 Sam. xv. 29). And prophetic passages like that in Kings, which so nobly declares that the heaven and the heaven of heavens cannot contain God (cf. Jer. xxiii. 24), or that of the second Isaiah which affirms that the Divine ways and purposes are as much higher than those of His people, as the heavens are higher than the earth (Isa. lv. 9), prove that the vivid anthropomorphic expressions of the popular teaching of the prophets ought in mere justice to be limited by these wider conceptions of the Divine Nature and attributes. These passages are quite enough to clear the prophets of the accusation of entertaining such gross and crude ideas of Deity as those which Xenophanes ridiculed, and which find their embodiment in most mythologies.
There is indeed a sense in which all thinking, not only thought about God, but about the natural world, must be anthropomorphic. Man is unquestionably "the measure of all things," and he measures by a human standard. He interprets the world without in terms of his own consciousness; he imposes the forms and moulds of his own mind upon the universal mass of things. Time, space, matter, motion, number, weight, organ, function,--what are all these but inward conceptions by which the mind reduces a chaos of conflicting impressions to order and harmony? What the external world may be, apart from our ideas of it, no philosopher pretends to be able to say; and an equal difficulty embarrasses those who would define what the Deity is, apart from His relations to man. But then it is only those relations that really concern us; everything else is idle speculation, little becoming to creatures so frail and ephemeral as we.
