As for a sluggard in soul matters, he is indeed void of understanding, for _he trifles with matters which demand his most earnest heed_. Man, hast thou never cultivated thy heart? Hast the ploughshare never broken up the clods of thy soul? Has the seed of the Word never been sown in thee? or has it taken no root? Hast thou never watered the young plants of desire? Hast thou never sought to pull up the weeds of sin that grow in thy heart? Art thou still a piece of the bare common or wild heath? Poor soul! Thou canst trim thy body, and spend many a minute at the glass; dost thou not care for thy soul? How long thou takest to decorate thy poor flesh, which is but worm's meat, or would be in a minute if God took away thy breath! And yet all the while thy soul is uncombed, unwashed, unclad, a poor neglected thing. Oh it should not be so. You take care of the worse part and leave the better to perish through neglect. This is the height of folly! He that is a sluggard as to the vineyard of his heart is a man void of understanding. If I must be idle, let it be seen in my field and my garden, but not in my soul. Or are you a Christian? Are you really saved, and are you negligent in the Lord's work? Then, indeed, whatever you may be, I cannot help saying you have too little understanding; for surely, when a man is saved himself, and understands the danger of other men's souls, he must be in earnest in trying to pluck the firebrands from the flame. A Christian sluggard! Is there such a being? A _Christian_ man on half time? A Christian man working not at all for his Lord; how shall I speak of him? _Time_ does not tarry, DEATH does not tarry, HELL does not tarry; Satan is not lazy, all the powers of darkness are busy: how is it that you and I can be sluggish, if the Master has put us into his vineyard? Surely we must be void of understanding if, after being saved by the infinite love of God, we do not spend and be spent in his service. The eternal fitness of things demands that a saved man should be an earnest man.
