It is not a strange thing, then, for the soul to find its life in God. This is its native air. God as the Environment of the soul has been from the remotest age the doctrine of all the deepest thinkers in religion. How profoundly Hebrew poetry is saturated with this high thought will appear when we try to conceive of it with this left out. True poetry is only science in another form. And long before it was possible for religion to give scientific expression to its greatest truths, men of insight uttered themselves in psalms which could not have been truer to Nature had the most modern light controlled the inspiration. "As the hart panteth after the water-brooks, so panteth my soul after Thee, O God." What fine sense of the analogy of the natural and the spiritual does not underlie these words. As the hart after its Environment, so man after his; as the water-brooks are fitly designed to meet the natural wants, so fitly does God implement the spiritual need of man. It will be noticed that in the Hebrew poets the longing for God never strikes one as morbid, or unnatural to the men who utter it. It is as natural to them to long for God as for the swallow to seek her nest. Throughout all their images no suspicion rises within us that they are exaggerating. We feel how truly they are reading themselves, their deepest selves. No false note occurs in all their aspiration. There is no weariness even in their ceaseless sighing, except the lover's weariness for the absent--if they would fly away, it is only to be at rest. Men who have no soul can only wonder at this. Men who have a soul, but with little faith, can only envy it. How joyous a thing it was to the Hebrews to seek their God! How artlessly they call upon Him to entertain them in His pavilion, to cover them with His feathers, to hide them in His secret place, to hold them in the hollow of His hand or stretch around them the everlasting arms! These men were true children of Nature. As the humming-bird among its own palm-trees, as the ephemera in the sunshine of a summer evening, so they lived their joyous lives. And even the full share of the sadder experience of life which came to all of them but drove them the further into the Secret Place, and led them with more consecration to make, as they expressed it, "the Lord their portion." All that has been said since from Marcus Aurelius to Swedenborg, from Augustine to Schleiermacher of a besetting God as the final complement of humanity is but a repetition of the Hebrew poets' faith. And even the New Testament has nothing higher to offer man than this. The psalmist's "God is our refuge and strength" is only the earlier form, less defined, less practicable, but not less noble, of Christ's "Come unto Me, and I will give you rest."
