While we look upon the lazy man's vineyard let us also peep into the ungodly sluggard's heart. He does not care about repentance and faith. To think about his soul, to be in earnest about eternity, is too much for him. He wants to take things easy, and have a little more folding of the arms to sleep. What is growing in his mind and character? In some of these spiritual sluggards you can see drunkenness, uncleanness, covetousness, anger, and pride, and all sorts of thistles and nettles; or where these ranker weeds do not appear, by reason of the restraint of pious connections, you find other sorts of sin. The heart cannot be altogether empty, either Christ or the devil will possess it. My dear friend, if you are not decided for God, you cannot be a neutral. In this war every man is for God or for his enemy. You cannot remain like a sheet of blank paper. The legible handwriting of Satan is upon you--can you not see the blots? Unless Christ has written across the page his own sweet name, the autograph of Satan is visible. You may say, "I do not go into open sin; I am moral," and so forth. Ah, if you would but look, and consider, and search into your heart, you would see that enmity to God and to his ways, and hatred of purity, are there. You do not love God's law, nor love his Son, nor love his gospel, you are alienated in your heart, and there is in you all manner of evil desires and vain thoughts, and these will flourish and increase so long as you are a spiritual sluggard, and leave your heart uncultivated. O, may the Spirit of God arouse you; may you be stirred to anxious, earnest thought, and then you will see that these rank growths must be uprooted, and that your heart must be turned up by the plough of conviction, and sown with the good seed of the gospel, till a harvest rewards the great Husbandman. Friend, if you believe in Christ, I want to peep over the hedge into _your heart_ also, if you are a sluggish Christian; for I fear that nettles and thistles are threatening you also. Did I not hear you sing the other day-- "'Tis a point I long to know"?
