And some of you have come to this point, that you positively rather like the titillation and excitement, slight though it may be, which is produced by coming in contact now and then with a good, wholesome, rousing Christian appeal. Not that you ever intend to do anything, but it is pleasant to see a man in earnest, and preaching as if he believed what he was saying. And so perhaps some of you are feeling here to-night. Ah! my dear friends, it is possible for a man to live by the side of Niagara until he cannot hear the cataract; and it is an awful thing for men and women to live under the sound of Christian teaching until it produces no more effect upon their wills and natures than the ringing of the church bells, to which they pay no attention. You do not know the despair that comes over us preachers time after time, as we look down upon the faces of our congregations, and feel, 'What _shall_ I do to put a sharp enough point upon this truth to get it into the heart of some man that has been sitting there as long as I have been standing here, and is never a bit the better for it?' Our most earnest preaching is like putting a red-hot iron into a pond: the cold water puts it out and closes above it, and there is no more heard nor seen of it. Our old Puritan forefathers used to talk about 'gospel-hardened hearers.' I believe that there are people listening to me now who have become so inured to Christian preaching that, like artillery horses, they will not move a muscle or quiver if a whole battery of cannon is fired off under their noses. God knows I despair sometimes, many a time, when I think of the hundreds of people to whom I speak, year after year, and how there seems next to nothing in the world to come of it all. III. Now lastly, notice here the rebuke of this negligence of the light. 'He began to upbraid the cities.' But oh! we shall misunderstand Him and His purpose if we think that that upbraiding was anything but the sorrowful expression of His own loving heart, which warned of what was coming in order that He might never need to send it. '_Woe_ unto you; _woe_ unto you,' and His own lips quivered and His own heart felt the woe, as He laid bare the sin and foreannounced the retribution.
