A blunt sword will not cut; a dull sermon will not reach the conscience. The sword must be sharpened, and the sermon must be sharpened too. The preacher’s laziness or half-heartedness, want of earnest faith in Christ and earnest love to men, blunts the edge of his sermons. Ah! he needs to be sharpened himself; stirred up continually to fresh energy and communion with his Savior, and affectionate interest for his fellow-men. Nothing prevents dulness so effectually as energy and zeal. The snore from the pew is often only the echo of the snore from the pulpit.
