The will of natural man is the worst part about him. The worst thing he has, the greatest enemy he has, is his own heart and will. It is the corrupt will of a man that keeps him under the power of his sins, and keeps him off the power of an ordinance that would procure his everlasting good. I speak it the rather to dash that dream of wicked men, when they do ill, and speak ill, yet (say they), “my heart is good.” No, truly, if thy life be naught, thy heart is worse. It is the worst thing thou hast about thee… The deceitfulness of the heart is above all; the masterfulness of the heart is beyond all that we can conceive. A man may discern a man’s life, “but the heart is deceitful above all things and beyond cure.” The will of man is uncontrollable, it will stand out against all reasons and arguments, and nothing can move the will except God work upon it.
