With Him all that the past generations "had willed, or hoped, or dreamed of good" came actually to exist. He made what had been aspiration only the basis of an actual Kingdom of God. As one of its primary moral foundations He laid down the radical indissolubility of marriage, and made visible to all men the breadth of the law given in the Decalogue by forbidding even wandering desires. In doing this He completely surpassed all Old Testament teaching, and set up a standard which Christian communities as such have held to hitherto, but which from lack of elevation and earnestness they seem inclined in these days to let slip. That such a standard was ever set up was the work of a Divine revelation of a perfectly unique kind, working through long ages of upward movement. Humanity has been dragged upwards to it most unwillingly. Men have found difficulty in living at that height, and nothing is easier than to throw away all the gain of these many centuries. All that is needed is a plunge or two downwards. But if ever these plunges are taken, the long, slow effort upwards will only have to be begun again, if family life is to be firmly established, and purity is to become a permanent possession of men.
With the commands we now have to consider, we leave altogether the region of strict law, and enter entirely upon that of aspiration and of feeling. Kindness, by its very nature, eludes the rude compulsion of law, properly so called. It ceases to be kindness when it loses spontaneity and freedom. Precept, therefore, not law, is the utmost that any lawgiver can give in respect to it; and this is precisely what we have in Deuteronomy, so far as it endeavours to incite men to gentleness, goodness, and courtesy to one another. The author gives his people an ideal of what they ought to be in these respects, and presses it home upon them with the heartfelt earnestness which distinguishes him. That is all; but yet, if we are to do justice to him as a lawgiver, we must consider and estimate the moral value of these precepts; for, properly speaking, they are the flower of his legal principles, and they reveal in detail, and therefore, for the average man, most impressively, the spirit in which his whole legislation was conceived. In the abstract no doubt he had told us that love--love to Yahweh--was to be the fundamental thing, and we have seen how deep and wide-reaching that announcement was. But a review of the precepts which indicate how he conceived that love to God should affect men's relations with men, will give that general principle a definiteness and a concreteness more impressive than a thousand homilies. For the conception that a relation of love is the only fit relation between man and God, could not, if it were sincerely taken up, fail to throw light upon men's true relations to each other. Consequently the great declaration of the sixth chapter was bound to re-echo in the precepts to guide conduct, giving new sanctity and breadth to all man's duty to his fellows.
Of course the risk of great failure was nigh at hand: for men may be intellectually convinced that love is the element in which life ought to be lived, and may proclaim it, who are far from being actually penetrated and filled with love, tested and increased by communion with God. As a result, much talk about love and kindly human duty has fallen with but little impulsive power upon the hearts of men. When, however, it is felt to be the expression of a present experience, such exhortation has power to move men as no other words can do. And the author of Deuteronomy was one of those who had this divinely given secret. In all parts of his book you find his words becoming winged with power, wherever love to God and man is even remotely touched upon. If our hypothesis as to the age in which he lived and wrote be correct, his must have been one of those high and rare natures which are not embittered by persecution or contemptuous neglect. Long before our Lord had spoken His decisive words on our duty to our neighbour, or St. Paul had written his great hymn to love, this man of God had been chosen to feel the truth, and had suffused his book with it, so that the only principle which can be recognised as binding together all his precepts is the central principle of the New Testament. Of course that made his ideal too high for present realisation; but he gained more than he lost; for, from Jeremiah and Josiah downwards through the years, all the noblest of his people responded to him. The splendour of his thought cast reflections upon their minds, and these glowed and shone amid the meaner lights which Pharisaism kindled and cherished, till He came whose right it was to reign. Then Deuteronomy's true rank was seen; for from it Christ took the answers by which He repelled Satan in the temptation, and from it, too, He took that commandment which He called the first and greatest. Of course the humanity of the book had not, in expression at least, the imperial sweep of Christian brotherhood which makes all men equal, so that for it there is neither Jew nor Gentile, neither wise nor unwise, neither male nor female, neither bond nor free. But _all_ the chosen people are included in its sympathy; and in this field, without undue interference with private life, the author sets forth by specimen cases how the fraternal feeling should manifest itself in loving, neighbourly kindness.
