But the Intercessor does more than secure for the sinful a space for repentance: He who obtains the respite takes means to render it effectual. The two chief applications employed in husbandry to stimulate growth and fruitfulness are digging and manuring: these accordingly the dresser of the vineyard undertakes to apply in the interval to the barren fig-tree. I think something may be gained here by descending into the particulars. One of these agricultural operations imparts to the tree the elements of fruitfulness, and the other enables the tree to make these elements its own. Digging gives nothing to the tree; but it makes openings whereby gifts from another quarter may become practically available. The manure contains the food which the plant must receive, and assimilate, and convert into fruit; but if the hardened earth were not made loose by digging, the needed aliment would never reach its destination. Similar processes are applied in the spiritual culture: certain diggings take place around and among the roots of barren souls, as well as of barren fig-trees. Bereavements and trials of various kinds strike and rend; but these cannot by themselves renew and sanctify. They may give pain, but cannot impart fertility: the spirit much distressed may be as unfruitful as the spirits that are at ease in Zion. These rendings, however, are most precious as the means of opening a way whereby the elements of spiritual life conveyed by the word and the Spirit may reach their destination. The Lord who pours in the food for the sustenance of a soul, stirs that soul by his providence, so that grace may reach the root and be taken in. As the constituents of fruit, held in solution by air and water, cannot freely reach the plant whose roots lie under a long unbroken and indurated soil, so the grace of God contained in the preached Gospel is kept at bay by a carnal mind and a seared conscience. It is when afflictions rend the heart, as a ploughshare tears up the ground, that the elements of life long offered are at length received. It is thus that providence and grace conspire to achieve the purpose of God in the salvation of men. In this work mercy and judgment meet; and saved sinners, on earth and in heaven, put both together in their song of praise (Ps. ci. 1.)
