The analogy being true to nature is instantly recognised and easily appreciated. There is a condition of heart which corresponds to the smoothness, hardness, and wholeness of a frequented footpath, that skirts or crosses a ploughed field. The spiritual hardness is like the natural in its cause as well as in its character. The place is a thoroughfare; a mixed multitude of this world's affairs tread over it from day to day, and from year to year. It is not fenced like a garden, but exposed like an uncultivated common. That secret of the Lord, "Enter into thy closet," and "shut the door," is unknown; or if known, neglected. The soil, trodden by all comers, is never broken up and softened by a thorough self-searching. A human heart may thus become marvellously callous both to good and evil. The terrors of the Lord and the tender invitations of the Gospel are alike ineffectual. Falling only upon the external senses, they are swept off by the next current; as the solid grain thrown from the sower's hand rattles on the smooth hard road side, and lies on the surface till the fowls carry it away. The parallel between the material and the moral here is more close and visible in the original than it appears in the English version. But our language is capable in this instance, like the Greek, of expressing by one phrase equally the moral and the material failure: "Every one that hears the word of the kingdom and does not take it in" (μὴ συνιέντος). The cause of the failure in both departments is, that the soil, owing to its hardness, does not take the seed into its bosom. The seed is good: "The word of God is quick and powerful;"--that is, it "is living, and puts forth energy."[9] Like buried moistened seed it swells and bursts, and forces its way through opposing obstacles. A heart of clay, smoothed and hardened on the surface, may hold it out for a lifetime; but a heart of stone could not keep it down, if it were once admitted, for a single day. [9] Ζ͂ῶν γὰρ ὁ λόγος τοῦ Θεοῦ, καὶ ἐνεργὴς.--HEB. iv. 12. "Behold the Lamb of God, which taketh away the sin of the world;" "If any man thirst, let him come unto me and drink;" "Believe on the Lord Jesus Christ, and thou shalt be saved;"--these and many such great solid seed-grains rain from heaven upon us in this land: shall we close all the avenues to our hearts and so leave that seed lying on the surface till the enemy carry it away? or shall the groanings which cannot be uttered, the convictions of sin in the conscience, rend at length the seared crust, that the seed may enter and occupy the life for God?
