Now the great idea that is here suggested to us connects this Divine joy with strength--the joy is an inspiration of energy. By the nature of things joy is exhilarating, while pain is depressing. Physiologists recognise it as a law of animal organisms that happiness is a nerve tonic. It would seem that the same law obtains in spiritual experience. On the other hand, nothing is more certain than that there are enervating pleasures, and that the free indulgence in pleasure generally weakens the character; with this goes the equally certain truth that men may be braced by suffering, that the east wind of adversity may be a real stimulant. How shall we reconcile these contradictory positions? Clearly there are different kinds and grades of delight, and different ways of taking and using every form of gladness. Pure hedonism cannot but be a weak system of life. It is the Spartan, not the Sybarite, who is capable of heroic deeds. Even Epicurus, whose name has been abused to shelter low pleasure-seeking, perceived, as clearly as "The Preacher," the melancholy truth that the life that is given over to the satisfaction of personal desires is but "vanity of vanities." The joy that exhilarates is not sought as a final goal. It comes in by the way when we are pursuing some objective end. Then this purest joy is as far above the pleasure of the self-indulgent as heaven is above hell. It may even be found side by side with bodily pain, as when martyrs exult in their flames, or when stricken souls in more prosaic circumstances awake to the wonderful perception of a rare Divine gladness. It is this joy that gives strength. There is enthusiasm in it. Such a joy not being an end in itself is a means to a great practical end. God's glad children are strong to do and bear His will, strong in their very gladness.
This was good news to the Jews, outwardly but a feeble flock and a prey to the ravening wolves from neighbouring lands. They had recovered hope after building their walls; but these hastily constructed fortifications did not afford them their most secure stronghold. Their refuge was God. They carried bows and spears and swords; but the strength with which they wielded these weapons consisted in the enthusiasm of a Divine gladness--not the orgiastic fury of the heathen, but the deep, strong joy of men who knew the secret of their Lord, who possessed what Wordsworth calls "inward glee." This joy was essentially a moral strength. It bestowed the power wherewith to keep the law. Here was the answer to the discouragement of the people in their dawning perception of the lofty requirements of God's holy will. The Christian can best find energy for service, as well as the calm strength of patience, in that still richer Divine gladness which is poured into his heart by the grace of Christ. It is not only unfortunate for anybody to be a mournful Christian; it is dangerous, hurtful, even wrong. Therefore the gloomy servant of God is to be rebuked for missing the Divine gladness. Seeing that the source of it is in God, and not in the Christian himself, it is attainable and possible to the most sorrowful. He who has found this "pearl of great price" can afford to miss much else in life and yet go on his way rejoicing.
It was natural that the Jews should have been encouraged to give expression to the Divine joy at a great festival. The final harvest-home of the year, the merry celebration of the vintage, was then due. No Jewish feast was more cheerful than this, which expressed gratitude for "wine that maketh glad the heart of man." The superiority of Judaism over heathenism is seen in the tremendous contrast between the simple gaiety of the Jewish Feast of Tabernacles and the gross debauchery of the Bacchanalian orgies which disgraced a similar occasion in the pagan world. It is to our shame in modern Christendom that we dare not imitate the Jews here, knowing too well that if we tried to do so we should only sink to the heathen level. Our Feast of Tabernacles would certainly become a Feast of Bacchus, bestial and wicked. Happily the Jews did not feel the Teutonic danger of intemperance. Their festival recognised the Divine bounty in nature, in its richest, ripest autumn fruitfulness, which was like the smile of God breaking out through His works to cheer His children. Bivouacking in greenwood bowers, the Jews did their best to return to the life of nature and share its autumn gladness. The chronicler informs us that since the days of Joshua the Jews had never observed the feast as they did now--never with such great gladness and never so truly after the directions of their law. Although the actual words he gives as from The Law[231] are not to be found in the Pentateuch, they sum up the regulations of that work. This then is the first application of The Law which the people have received with so much distress. It ordains a glad festival. So much brighter is religion when it is understood and practised than when it is only contemplated from afar! Now the reading of The Law can go on day by day, and be received with joy.
