We have committed ourselves, in our mode of dealing with the subject of these lectures, to the guidance of Scripture; and I have already, in the opening lecture, alluded to the doubt, which might arise in some minds that this method might carry us away from the living questions of the present age. But long experience has taught me to be very confident in this method of study. It is astonishing how directly, when trusting to the leading hand of Scripture, one is conducted to the heart of almost any subject, and how frequently one is thus compelled to take up delicate aspects of present questions which one would otherwise timidly avoid; while there is, besides, this other great advantage, that one can always go forward with a firm step, having at one's back a Divine warrant and authority. To-day we shall have an illustration of this; for the method which we are obeying will carry us straight into the midst of the burning questions of the hour; and the example of the prophets will press on our attention an aspect of ministerial duty which the times are urgently clamouring for, but which it is by no means easy to face. In our last lecture we were occupied with the call of the prophet to the service of God; to-day we have to study wherein consisted this service itself. * * * * * Here we are at once confronted with a contrast between the work of Old Testament prophets and that of modern ministers, to which it is by no means easy to adjust the mind. Our message in modern times is addressed to the individual; but the message of the prophets was addressed to the nation. The unit in our minds is always the soul; we warn every man to flee from the wrath to come; we reason and wrestle with him in the name of Heaven; we watch over the growth of his character; and we estimate our success by the number of individuals brought into the kingdom. In the prophets there is a complete absence of all this. They are no less in earnest; their aim is equally clear before them; but the unit in their minds is different: it is the Jewish state, or at least the city of Jerusalem, as a whole. A recent commentator[16] on Isaiah has raised the question, whether Isaiah has a gospel for the individual. He makes out that he has; but it is in a somewhat round-about way; and it is not done without, to some extent, attributing to Isaiah a point of view which was not his. It was Christ who introduced the modern point of view. He was the discoverer of the individual. It was He who taught the world to believe in the dignity and destiny of the single soul; and He trained His ministers to seek and save it.
