The psalm, too, breathes the very spirit of sunny confidence and of perfect rest in God. We have referred to the absence of traces of sorrow, and to the predominant tone of hopefulness, as possibly favouring the supposition of an early origin. But it matters little whether they were young eyes which looked so courageously into the unknown future, or whether we have here the more solemn and weighty hopes of age, which can have few hopes at all, unless they be rooted in God. The spirit expressed in the psalm is so thoroughly David's, that in his younger days, before it was worn with responsibilities and sorrows, it must have been especially strong. We may therefore fairly take the tone of this song of the Shepherd God as expressing the characteristic of his godliness in the happy early years. In his solitude he was glad. One happy thought fills the spirit; one simple emotion thrills the chords of his harp. No doubts, or griefs, or remorse throw their shadows upon him. He is conscious of dependence, but he is above want and fear. He does not ask, he has--he possesses God, and is at rest in Him. He is satisfied with that fruition which blesseth all who hunger for God, and is the highest form of communion with Him. As the present has no longings, the future has no terrors. All the horizon is clear, all the winds are still, the ocean at rest, "and birds of peace sit brooding on the charmed wave." If there be foes, God holds them back. If there lie far off among the hills any valley of darkness, its black portals cast no gloom over him, and will not when he enters. God is his Shepherd, and, by another image, God is his Host. The life which in one aspect, by reason of its continual change, and occupation with outward things, may be compared to the journeyings of a flock, is in another aspect, by reason of its inward union with the stability of God, like sitting ever at the table which His hand has spread as for a royal banquet, where the oil of gladness glistens on every head, and the full cup of Divine pleasure is in every hand. For all the outward and pilgrimage aspect, the psalmist knows that only Goodness and Mercy--these two white-robed messengers of God--will follow his steps, however long may be the term of the days of his yet young life; for all the inward, he is sure that, in calm, unbroken fellowship, he will dwell in the house of God, and that when the twin angels who fed and guided him all his young life long have finished their charge, and the days of his journeyings are ended, there stretches beyond a still closer union with his heavenly Friend, which will be perfected in His true house "for ever." We look in vain for another example, even in David's psalms, of such perfect, restful trust in God. These clear notes are perhaps the purest utterance ever given of "the peace of God which passeth all understanding."
Such were the thoughts and hopes of the lad who kept his father's sheep at Bethlehem. He lived a life of lofty thoughts and lowly duties. He heard the voice of God amidst the silence of the hills, and the earliest notes of his harp echoed the deep tones. He learned courage as well as tenderness from his daily tasks, and patience from the contrast between them and the high vocation which Samuel's mysterious anointing had opened before him. If we remember how disturbing an influence the consciousness of it might have wrought in a soul less filled with God, we may perhaps accept as probably correct the superscription which refers one sweet, simple psalm to him, and may venture to suppose that it expresses the contentment, undazzled by visions of coming greatness, that calmed his heart. "Lord, my heart is not haughty, nor mine eyes lofty; neither do I exercise myself in great matters, or in things too high for me. Surely I have smoothed and quieted my soul: like a weanling on his mother's (breast), like a weanling is my soul within me." (Psa. cxxxi.) So lying in God's arms, and content to be folded in His embrace, without seeking anything beyond, he is tranquil in his lowly lot.
