The Lord's people are spoken of here as at once "springing up" under the influence of the water poured and of the floods given. We cannot mistake the spiritual meaning of the figure, as it is so clear and certain. In those burning regions where rain does not fall at all seasons from the skies, as in our dripping clime, the effect of copious showers falling upon the parched vegetation is almost miraculous. A few days completely reverse the scene, and on every side vegetation springs up as if it started with gigantic growth out of the bosom of the heated soil. To this the figure in the text alludes, "They shall spring up," that is, Zion's children, "as among the grass," with all that young and active growth which so clearly manifests the power and the blessing of God.
But what may we understand by the expression "grass?" May we not interpret it as emblematic of the flesh, according to the words of the prophet, "All flesh is grass!" (Isa. 40:6.) All the pride, pomp, and beauty of the flesh are but as grass, for "all the glory of man is as the flower of grass" (1 Peter 1:24), which, when cut down by the scythe, soon withers, is gathered into heaps, and swept away out of the field. In this point of view we may consider the children of God to spring up amongst the sons of men as flowers among the grass, bedecking it with beauty—the only beautiful objects among the green blades. O how blessed it is to see children of God springing up here and there amongst the grass which everywhere so thickly covers the mead!
Time may have been when you were hidden beneath the grass—when, though a flower in God's sight, your root was in the dust, and you lay undistinguished amidst the thick herbage. But being a flower, one of the Redeemer's own lilies, among whom he feeds (Song Sol. 6:3), when the rain of heaven dropped upon you, you sprang up amid the crowded blades which before hid you from view.
