I am glad to be told by Solomon so plainly that a slothful man is void of understanding, for it is useful information. I have met with persons who thought they perfectly understood the doctrines of grace, who could accurately set forth the election of the saints, the predestination of God, the firmness of the divine decree, the necessity of the Spirit's work, and all the glorious doctrines of grace which build up the fabric of our faith; but these gentlemen have inferred from these doctrines that they have to do nothing, and thus they have become sluggards. Do-nothingism is their creed. They will not even urge other people to labor for the Lord, because, say they, "God will do his own work. Salvation is all of grace!" The notion of these sluggards is that a man is to wait, and do nothing; he is to sit still, and let the grass grow up to his ankles in the hope of heavenly help. To arouse himself would be an interference with the eternal purpose, which he regards as altogether unwarrantable. I have known him look sour, shake his aged head, and say hard things against earnest people who were trying to win souls. I have known him run down young people, and like a great steam ram, sink them to the bottom, by calling them unsound and ignorant. How shall we survive the censures of this dogmatic person? How shall we escape from this very knowing and very captious sluggard? Solomon hastens to the rescue and extinguishes this gentleman by informing us that he is void of understanding. Why, he is the standard of orthodoxy, and he judges everybody! Yet Solomon applies another standard to him, and says he is void of understanding. He may know the doctrine, but he does not understand it; or else he would know that the doctrines of grace lead us to seek the grace of the doctrines; and that when we see God at work we learn that he worketh in us, not to make us go to sleep, but to will and to do of his own good pleasure. God's predestination of a people is his ordaining them unto good works that they may show forth his praise. So, if you or I shall from any doctrines, however true, draw the inference that we are warranted in being idle and indifferent about the things of God, we are void of understanding; we are acting like fools; we are misusing the gospel; we are taking what was meant for meat and turning it into poison. The sluggard, whether he is sluggish about his business or about his soul, is a man void of understanding.
