These common blessings of Providence avail to interpret deeper mysteries. Since the world is full of happy creatures nourished by Him, it is a reasonable faith that His work is all of a piece, and that in all His dealings the twin attributes of righteousness and loving-kindness rule. There are enough plain tokens of God's character in plain things to make us sure that mysterious and apparently anomalous things have the same character regulating them. In ver. 17_b_ the word rendered _loving_ is that usually employed of the objects of loving-kindness, God's "favoured ones." It is used of God only here and in Jer. iii. 12, and must be taken in an active sense, as _One who exercises loving-kindness_. The underlying principle of all His acts is Love, says the psalmist, and there is no antagonism between that deepest motive and Righteousness. The singer has indeed climbed to a sun-lit height, from which he sees far and can look down into the deep of the Divine judgments and discern that they are a clear-obscure.
He does not restrict this universal beneficence when he goes on to lay down conditions on which the reception of its highest forms depend. These conditions are not arbitrary; and within their limits, the same universality is displayed. The lower creation makes its mute appeal to God, but men have the prerogative and obligation of calling upon Him with real desire and trust. Such suppliants will universally be blessed with a nearness of God to them, better than His proximity through power, knowledge, or the lower manifestations of His loving-kindness, to inferior creatures. Just as the fact of life brought with it certain wants, which God is bound to supply, since He gives it, so the fear and love of Him bring deeper needs, which He is still more (if that were possible) under pledge to satisfy. The creatures have their desires met. Those who fear Him will certainly have theirs; and that, not only in so far as they share physical life with worm and bee, whom their heavenly Father feeds, but in so far as their devotion sets in motion a new series of aspirations, longings, and needs, which will certainly not be left unfulfilled. "Food" is all the boon that the creatures crave, and they get it by an easy process. But man, especially man who fears and loves God, has deeper needs, sadder in one aspect, since they come from perils and ills from which he has to be saved, but more blessed in another, since every need is a door by which God can enter a soul. These sacreder necessities and more wistful longings are not to be satisfied by simply opening God's hand. More has to be done than that. For they can only be satisfied by the gift of Himself, and men need much disciplining before they will to receive Him into their hearts. They who love and fear Him will desire Him chiefly, and that desire can never be balked. There is a region, and only one, in which it is safe to set our hearts on unattained good. They who long for God will always have as much of God as they long for and are capable of receiving.
But notwithstanding the universality of the Divine loving-kindness, mankind still parts into two sections, one capable of receiving the highest gifts, one incapable, because not desiring them. And therefore the One Light, in its universal shining, works two effects, being lustre and life to such as welcome it, but darkness and death to those who turn from it. It is man's awful prerogative that he can distil poison out of the water of life, and can make it impossible for himself to receive from tender, universal Goodness anything but destruction.
The singer closes his song with the reiterated vow that his songs shall never close, and, as in the earlier part of the psalm, rejoices in the confidence that his single voice shall, like that of the herald angel at Bethlehem, be merged in the notes of "a multitude praising God and saying, Glory to God in the highest."
