When He came to it, He found nothing but leaves… – Mark 11:13

The Searcher finds nothing but leaves where fruit might have been expected. Nothing but leaves mean nothing but lies. Is that a harsh expression? If I profess faith, and have no faith, is not that a lie? If I profess repentance, and have not repented, is not that a lie? If I unite with the people of the living God, and yet have no fear of God in my heart, is not that a lie? If I come to the communion-table, and partake of the bread and wine, and yet never discern the Lord’s body, is not that a lie? If I profess to defend the doctrines of grace, and yet am not assured of the truth of them, is not that a lie? If I have never felt my depravity; if I have never been effectually called, never known my election of God, never rested in the redeeming blood, and have never been renewed by the Spirit, is not my defense of the doctrines of grace a lie? If there is nothing but leaves, there is nothing but lies, and the Saviour sees that it is so. All the verdure of green leaf to him without fruit is but so much deceit. Profession without grace is the funeral pageantry of a dead soul. Religion without holiness is the light which comes from rotten wood-the phosphorescence of decay: I speak dread words, but how can I speak less dreadfully than I do? If you and I have but a name to live, and are dead, what a state we are in! Ours is something worse than corruption: it is the corruption of corruption. To profess religion and live in sin, is to sprinkle rose-water upon a dunghill, and leave it a dunghill still. To give a spirit an angel’s name when it bears the devil’s character, is almost to sin against the Holy Ghost. If we remain unconverted, of what use can it be to have our name written among the godly? An empty profession is a practical curse; and should it not receive the censure of the Lord of truth? ~ C.H. Spurgeon
