I. This is illustrated here by a comparison, v. 8. When a vine is so blasted and withered that there seems to be no sap nor life in it, and therefore the dresser of the vineyard is inclined to pluck it up or cut it down, yet, if ever so little of the juice of the grape, fit to make new wine, be found, though but in one cluster, a stander-by interposes, and says, Destroy it not, for a blessing is in it; there is life in the root, and hope that yet it may become good for something. Good men are blessings to the places where they live; and sometimes God spares whole cities and nations for the sake of a few such in them. How ambitious should we be of this honor, not only to be distinguished from others, but serviceable to others!
