We must take heed to our doctrine about the total corruption of human nature. The corruption of human nature is no slight thing. It is no partial, skin-deep disease, but a radical and universal corruption of man's will, intellect, affections, and conscience. We are not merely poor and pitiable sinners in God's sight: we are guilty sinners; we are blameworthy sinners: we deserve justly God's wrath and God's condemnation. I believe there are very few errors and false doctrines of which the beginning may not be traced up to unsound views about the corruption of human nature. Wrong views of a disease will always bring with them wrong views of the remedy. Wrong views of the corruption of human nature will always carry with them wrong views of the grand antidote and cure of that corruption.
