2. How he illustrates it by a comparison taken from a sick and diseased body, all overspread with leprosy, or, like Job's, with sore boils, v. 5, 6. (1.) The distemper has seized the vitals, and so threatens to be mortal. Diseases in the head and heart are most dangerous; now the head, the whole head, is sick—the heart, the whole heart, is faint. They had become corrupt in their judgment: the leprosy was in their head. They were utterly unclean; their affection to God and religion was cold and gone; the things which remained were ready to die away, Rev. iii. 2. (2.) It has overspread the whole body, and so becomes exceedingly noisome; From the sole of the foot even to the head, from the meanest peasant to the greatest peer, there is no soundness, no good principles, no religion (for that is the health of the soul), nothing but wounds and bruises, guilt and corruption, the sad effects of Adam's fall, noisome to the holy God, painful to the sensible soul; they were so to David when he complained (Ps. xxxviii. 5), My wounds stink, and are corrupt, because of my foolishness. See Ps. xxxii. 3, 4. No attempts were made for reformation, or, if they were, they proved ineffectual: The wounds have not been closed, not bound up, nor mollified with ointment. While sin remains unrepented of the wounds are unsearched, unwashed, the proud flesh in them not cut out, and while, consequently, it remains unpardoned, the wounds are not mollified or closed up, nor any thing done towards the healing of them and the preventing of their fatal consequences.
