But it is characteristic of the large outlook of Deuteronomy that not only is the evil protested against; the universal human need which underlay it is acknowledged and supplied. Behind all the terrible aberrations of heathen soothsaying and divination the author saw hunger for a revelation of the will and purpose of God. That was worthy of sympathy, however inadequate and evil the substitutes elaborated for the really Divine means of enlightenment were. So he promises that the real need will be supplied by God's holy prophets. Nothing that savoured of ignorance or misapprehension of God's spirituality, or of unfaithfulness to Yahweh, could be tolerated; for Israel's God would supply all their need by a prophet from the midst of them, of their brethren, like unto Moses, in whose mouth Yahweh would put His words, and who should speak unto them all that He should command him. This is the broadest and most general legitimation of the prophet, as a special organ of revelation in Israel, that the Scripture contains. By it he is made one of the regularly constituted channels of Divine influence for his people. For it is evidently not one single individual, such as the Messiah, who is here foretold. That has been the interpretation received from the earlier Jews, and cherished in the Church up till quite modern times. But as Keil rightly says, the fact that this promise is set against any supposed need to have recourse to diviners and wizards, is in itself sufficient proof that the prophetic order is meant. It was not only in the far-off Messianic time that Israel was to find in this Divinely sent prophet that knowledge of God's will and purposes which it needed. Israel of all times, tempted by the customs of its heathen neighbours to go to the diviners, was to have in Yahweh's prophet a continual deliverance from the temptation. That implies that this Nabhi, or prophet like unto Moses, was to be continually recurring, at every turn and crisis of this nation's career.

Further, the direction in the end of the passage for testing the prophets, whether they were really sent of God or not, confirms this view. It would be singularly out of place in a promise which referred to the Messiah in an exclusive and primary fashion. He would never need testing of this sort, for He was to be the realisation and embodiment of Israel's highest aspirations. But if the passage means to give the prophets a place among the national organs of intercourse with Yahweh alongside of the priests, the necessity of distinguishing these true and Divinely given prophets from pretenders was urgent. The context, both before and after the promise, seems, therefore, to be decisively in favour of the general reference; and the phrases "like unto me," "like unto thee," i.e. Moses, when carefully examined, instead of weakening that inference, strengthen it. They are not used here as the similar phrase is used in Deut. xxxiv. 10: "And there hath not arisen a prophet since in Israel like unto Moses, whom Yahweh knew face to face." There the closeness of Moses' approach to Yahweh is the point in hand, and it is clearly stated that in that regard Moses was more favoured than any who had succeeded him. But here the comparison is between Moses and the prophets, in so far as mediation between Yahweh and His people was concerned. At Israel's own wish Moses had been appointed to hear the Divine voice. Israel had said "Let me not hear again the voice of Yahweh my God, neither let me see this great fire any more, that I die not." The prophet here promised was to be like Moses in that respect, but there is nothing to assert that he would be equal to Moses in power and dignity. On all grounds, therefore, the reference to the line of prophets is to be maintained.

Still, the interpretation thus reached does not exclude—it distinctly includes—the Messianic reference. If the passage promises that at all moments of difficulty and crisis in Israel's history, the will of God would be made known by a Divinely sent prophet, that would be specially true of the last and greatest crisis, the birth of the new time which the Messiah was to inaugurate. Whatever fulfilment the promise might receive previously to that, it could not be perfectly fulfilled without the advent of Him whose office it was to close up the history of the present world, and bring all things by a safe transition into the new Messianic world. That was the greatest crisis; and necessarily the prophet who spoke for Yahweh in it must be the crown of the long line of prophets. There is still a higher sense in which this promise has reference to the Messiah. He was to sum up and realise in Himself all the possibilities of Israel. Now they were the prophetic nation, the people who were to reveal God to mankind; and when they proved prevailingly false to their higher calling, the hopes of all who remained faithful turned to that "true" Israel which alone would inherit the promises. At one period, just before and in the Exile, the prophetic order would appear to have been looked upon as the Israel within Israel, to whom it would fall to accomplish the great things to which the seed of Abraham had been called. But the author of Second Isaiah, despairing even of them, saw that the destiny of Israel would be accomplished by one great Servant of Yahweh, who should outshine all other prophets, as He would surpass all other Israelite priests and Davidic kings. As the crown and embodiment of all that the prophets had aspired to be, the Messiah alone completely fulfilled this promise, and consequently the Messianic reference is organically one with the primary reference. They are so intimately interwoven that nothing but violence can separate them; and thus we gain a deeper insight into the wide reach of the Divine purposes, and the organic unity of the Divine action in the world. These form a far better guarantee for the recognition of Messianic prophecy here than the supposed direct and exclusive reference did. By not grasping too desperately at the view which more strikingly involves the supernatural, we have received back with "full measure pressed down and running over" the assurance that God was really speaking here, and that this, like all the promises of the Old Testament when rightly understood, is yea and amen in Christ.

But for our present purpose the primary reference of this passage to the prophetic line is even more important than the secondary but most vital reference to the Messiah. For it sets forth prophecy as the most potent instrument for the growth and furtherance of the religion of Israel. The prophet is here declared to be the successor of Moses, to be the inspired declarer of the Divine will to His people in cases which did not come within the sphere or the competency of the priest. The latter was, as we have seen, bound to work within the limits and on the basis of the revelation given by Moses. He was to carry out into execution what had been commanded, to keep alive in the hearts of the people the knowledge of their God as Moses had given it, to give "Torah" from the sanctuary in accordance with its principles. But here a nobler office is assigned to the prophet. He is to enlarge and develop the work of Moses. The Mosaic revelation is here viewed as fundamental and normative, but, in contrast to the views of later Judaism, as by no means complete. For the completion of it the prophet is here declared to be the Divinely chosen instrument, and he is consequently assigned a higher position in the purpose of God than either king or priest. He is raised far above the diviners by having his calling lifted into the moral sphere; and he excels both the other organs of national life in that, while they are largely bound by the past, he is called of God to initiate new and higher stages in the life of the chosen people. The ascending steps of the revelation begun by Moses were to be in his hands, and through him God was to reveal Himself in ever fuller measure.

Viewed thus, the prophetic order in Israel has a quite unique character. It is a provision for religious progress such as had no parallel elsewhere in the world; and this public acknowledgment of its Divine right is almost more remarkable. Wherever elsewhere in the world religion has been supposed to be Divinely given through one man, though modifications have indeed been made in later times, yet they have never been anticipated and provided for beforehand. Save in the case of Mohammedanism, which borrowed its idea of the office of the prophet from Judaism, there has never been a deliberate admission that God had yet higher things to reveal concerning Himself, still less has provision been made for the coming of that which was new to fulfil the old. And in modern times the revealer of new aspects of truth finds nowhere a welcome. Instead of being received as a messenger of God, even in the Christian Church he has always to face neglect, often persecution, and only if he be unusually fortunate does he live to see his message received. But in Israel, even in such ancient days as those we are dealing with, the progressive nature of God's Revelation of Himself was acknowledged, the reception of new truth was legitimised and looked for, and the highest place in the earthly kingdom of God was reserved for those whom God had enlightened by it. It is true of course that the nation as a whole never acted in accordance with this teaching. They did not obey the command given here, "Unto him shall ye hearken," and reiterated still more solemnly in the words, "And it shall come to pass, that whosoever will not hearken unto My words, which he shall speak in My name, I will require of him." The prophets for the most part spoke to their contemporaries in vain. Where they were not neglected they were persecuted, and many sealed their testimony with their blood. But the thought that Yahweh was educating His people step by step, and that at all times in their history He would have further revelations of Himself to make, is familiar to this writer. Therefore he welcomes the thought of advance in this region of things, and here solemnly enrols those who are to be the instruments of it among the ruling powers of the nation.

Now in religious thought this is quite unparalleled. Tenacious conservatism, based on the conviction that full truth has already been attained, has always been the mark of religious thinking. That a religious teacher should be able to see that the light of revelation, like the natural light, must come gradually, broadening by degrees into perfect day, and that he himself was standing only in the morning twilight, is a thing so remarkable that one is at a loss to account for it, save on the ground of the special nature of prophetic enlightenment. It was part of the office of the prophets to foresee and foretell the future. Smend is certainly in the right, as against those who have been teaching that the prophet was merely a preacher of genius, when he says that "in Amos and his successors prophecy is the starting-point of their whole discourse and action," and that "all new knowledge which they preach comes to them from the action of Yahweh which they foretell.... Consequently the greatness of a prophet is to be gathered from the measure in which he foresees the future."[95] This statement gives us the truth that lies between the two other extremes; for according to it the prophet proclaims and preaches religious truth, but he does so on the basis of what he perceives that God is about to do in the future. In other words, he proclaims new truth on the ground of the revelation God is about to make of Himself, which he is inspired to foresee and to interpret. His business is neither all foreseeing nor all teaching; it is teaching grounded upon foresight. Consequently it was impossible for the prophet to believe that change in religion was in itself evil. He knew to the contrary. Only change which should remove men from the Divinely given basis of the faith was evil; and such change, whatever credentials might accompany it, even though they might be miraculous, every faithful Israelite had been already warned most sternly to reject (Deut. xiii. 5). But when the impulse to advance came from Yahweh's manifestation of Himself, change was not only good, it was the indispensable test of faithfulness. They were not the true followers of Isaiah who, on the ground of his prophecy that Zion, as Yahweh's dwelling-place, should be delivered from destruction, rejected the prophecy of Jeremiah that Zion would fall before the Chaldeans. The really faithful men were those who had taken to heart the lessons Yahweh had set for His people in the century that lay between these two prophets; who saw that the time when the deliverance of Zion was necessary to the safety of the true religion was past, and that now the capture of Zion was necessary to its true development. And that is not a solitary case; it is an example of what was normal in the religious history of this people.

This did not escape the quick eye of John Stuart Mill. He says the religion of Israel "gave existence to an inestimably precious unorganised institution—the order (if it may be so termed) of prophets.... Religion, consequently, was not there, what it has been in so many other places, a consecration of all that was once established, and a barrier against further improvement." There always was the movement of pulsing life within it, and under the Divine guidance that movement was always upward. At some times it was comparatively shallow and slow, at others it was a deep and rushing tide. But it was always moving in directions which led straight to the great consummation of itself in the coming of Christ, who gathered up into His own life all the varied streams of revelation, and crowned and fulfilled them all. At no point in the progress from Moses to the Messiah do we touch rounded and completed truth; nor, according to the teaching of Scripture in this passage, were we meant to do so. The faithful among Israel had as their watchword the disio and pace of Dante. They saw before them a world of Divine "peace," which they knew lay still in the future, and the "desire" and yearning of their souls were always directed towards it. With inextinguishable hope they marched onward with uplifted faces, to which light reflected from that future gave at times a radiant gladness; and always they kept an open ear for those who saw what God was about to do at each turning of the way.

But granting that religion was thus progressive before men were spoken unto "by the Son," can we say or believe that, now that He has spoken, progress in this way is still possible? At first sight it would seem necessary to answer that question in the negative. The progressive revelation of God has come to its perfection in Jesus Christ; what then remains to us but to cling to that? Are we not bound to make resistance to progress, to any new view in religion, our first duty? Many act and speak as if that were the only possible course consistent with faithfulness. But we must distinguish. The revelation of God has, according to our Christian faith, reached not only its highest actual point, but also its highest possible point in Christ. God can do nothing more for His vineyard than He has done. As a manifestation of God, revelation is completed and closed in Christ. For it is impossible to manifest God to men more fully than in a man who reveals God in every thought and word and act.

But it is quite otherwise with the interpretation of the manifestation. In the earlier days this was provided for by a special inspiration of God, which made the holy men of old infallible in their interpretation of the revelation received up to their day, and that continued till the establishment of the Church. Since then the Holy Spirit is to be the guide of faithful men into all truth. Now in the way of interpreting Christ and His message progress is as much open to us as it was to Israel. A complete revelation of God must necessarily, at any given time up till the consummation of all things, contain in it a residuum of significance which, at that point of their experience, mankind has not felt the need of, nor has had the capacity to understand. As the world grows older, however, new outlooks, new environments, new circumstances continually appear, and they all insist upon being dealt with by the Church. In order to deal with them adequately and worthily, a faithful Church must turn to Christ to see what God would have it do; and if Christ be what we take Him to be, there will issue from Him a light, unseen or unnoticed before, to meet the hitherto unfelt need. Moreover, while our Lord Jesus Christ reveals God completely as the God of Redemption, and throws light upon all God's relations to man, a light which needs and admits of no supplementary addition, there are other aspects of the Divine character which He does not so entirely reveal. For example, God's relations to the world of nature, which are now being unveiled in a most striking manner, are dealt with comparatively rarely in the Gospels. Are we to shut our eyes to these as of no importance, and to allow them no influence upon our thoughts? Surely that cannot be demanded of us; for, to speak plainly, it is impossible. No one can remain unmoved when God and man are revealing themselves in the wondrous panorama of the world's life.
