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?
